Polymeric Sand at Home Depot: What to Buy
Two brands are on the shelf, two more are a few days away online, and which one you need depends almost entirely on how wide your joints are. Here is what is actually stocked, how many bags to buy, and when the landscape yard is the better trip.

In This Guide
The polymeric sand aisle at a big-box store is genuinely small — usually two brands, two colours each — and that limited choice is fine for most patios. The decision that actually matters is not which bag, but whether your joints are inside the width range printed on it.
Our Picks at a Glance
- Best In-Store Buy: Sakrete PermaSand — Standard Joint Width, 40 lb Bag
- Best Value Per Pound: Quikrete PowerLoc Jointing Sand — Standard Joint Width, 50 lb Bag
- Best for Wide Joints: Alliance Gator Maxx G2 — Premium, Wide Joints, 50 lb Bag
- Best Colour Retention: DOMINATOR Polymeric Sand — Premium, Standard to Wide Joints
1. What Home Depot Actually Stocks
In-store, expect two names: Sakrete PermaSand and Quikrete PowerLoc, usually in the masonry or hardscape aisle near the pavers rather than with the bagged play sand. Colours are typically limited to tan and grey, which covers the majority of concrete pavers and satisfies nobody with unusual stone.
Online is a different catalogue. Alliance Gator Maxx G2 and DOMINATOR are commonly listed for delivery or store pickup even where no store within an hour has a bag on the shelf. That matters, because those are the products rated for wide joints and irregular flagstone — the exact cases where the in-store options are the wrong purchase. The catch is lead time: they need ordering days ahead, and the classic sequence of failure is discovering that on the morning the pavers are laid and buying whatever is in the aisle instead.
Availability moves around by region and season, and the honest advice is to check your own store's stock online before driving over, particularly in spring when hardscape products sell through quickly. Store apps show live inventory by location, and it is worth checking two nearby stores rather than assuming the larger one has more.
2. The Four Options, Reviewed
We have used all four on real patios and paths. The differences that matter in practice are joint width tolerance, how much haze they leave on the paver faces, and how forgiving they are if the watering is not textbook.
Sakrete PermaSand
Standard Joint Width, 40 lb Bag
PermaSand is the bag most people leave a Home Depot with, and for a straightforward patio with joints in the normal range it is a perfectly good choice. It handles gaps from roughly an eighth of an inch to an inch, cures to a firm joint that keeps weeds and ants out, and costs less per bag than the premium alternatives. What it asks in return is discipline during installation. The watering step is where PermaSand separates careful installers from disappointed ones: too little and the binders never fully activate, leaving soft joints that wash out in the first storm, and too much floods the polymer out of the joint and onto the paver faces, where it dries as a haze that is genuinely difficult to remove. Follow the bag directions on the shower setting and the number of passes rather than eyeballing it. The other point worth knowing is that PermaSand is less tolerant of dust on the paver surface than the premium sands, so the sweep-and-blow step before watering matters more here than it does with a product like Gator Maxx. On smooth, non-porous concrete pavers this is rarely an issue. On tumbled, textured or porous stone, take the extra ten minutes with a leaf blower on low before the hose comes out.
Pros
- Stocked in-store at most locations, in the masonry aisle
- Handles joints from about 1/8 inch up to an inch
- Cheapest per bag of the genuine polymeric options
- Cures firm enough to resist weeds and ants
- Easy to find in tan and grey to match most pavers
Cons
- Less forgiving than premium sands if you over-water
- Haze is a real risk on textured or porous pavers
The Bottom Line
The sensible default if you are standing in the store today. Do the sweeping and watering properly and it performs; rush either and it is the first to show it.
Quikrete PowerLoc Jointing Sand
Standard Joint Width, 50 lb Bag
PowerLoc is Quikrete's polymeric jointing sand and the value play among the in-store options, mainly because it comes in 50 lb bags where much of the competition sells 40. On a large patio that difference adds up quickly. Performance is broadly comparable to PermaSand: it fills and locks joints in the standard range, cures firm, and keeps weeds and insects out of the gaps. It flows into narrow joints particularly well, which makes it a good match for tightly laid concrete pavers where a coarser sand tends to bridge across the top of the gap instead of filling it to depth. As with every polymeric sand, the failure modes are all in the process rather than the product. The surface must be bone dry before the bag is opened, the sand must be swept in and compacted properly so the joint is filled to within a few millimetres of the paver surface, and every trace has to come off the paver faces before watering. Where PowerLoc is less suitable is very wide joints and irregular flagstone, where the manufacturer's own limits apply and a wide-joint formulation is the correct purchase instead. Check the bag for the stated joint range before buying for anything unusual.
Pros
- 50 lb bags cover more area per dollar than 40 lb competitors
- Widely stocked and easy to reorder mid-project
- Good colour range for typical concrete pavers
- Sets firm and resists washout once properly cured
- Forgiving in narrow joints where thicker sands bridge
Cons
- Heavier bags are harder to handle on a long job
- Not rated for the widest joints or flagstone gaps
The Bottom Line
The best coverage per dollar on the shelf. If your joints are standard width and your budget matters, this is the one to load onto the cart.
Alliance Gator Maxx G2
Premium, Wide Joints, 50 lb Bag
Gator Maxx G2 is the product most installers reach for when the job is not a simple grid of concrete pavers, and it is the strongest performer of the sands you can get through Home Depot — though usually through the website rather than off the shelf. Two things justify the premium. First, joint width: it is rated for gaps up to around four inches, which brings irregular flagstone and wide-jointed natural stone into range, where the standard sands are limited to roughly an inch. Second, haze resistance. The binder system is less prone to depositing on the paver surface during watering, which removes the single most common way a polymeric sand job goes visibly wrong. It is also more tolerant of a slightly heavy hand with the hose, which matters if this is your first time using the product. None of that makes preparation optional — the surface still has to be dry, the joints still have to be filled to depth, and the paver faces still have to be swept and blown clean before watering. But the margin for error is wider than with the budget bags, and on an expensive stone patio that margin is cheap insurance. If your local store does not stock it, ordering online for delivery or store pickup is usually straightforward.
Pros
- Handles joints up to about four inches — flagstone territory
- Noticeably more haze-resistant than budget sands
- More tolerant of imperfect watering technique
- Stays flexible enough to resist cracking through freeze-thaw
- Available through Home Depot's site even where stores skip it
Cons
- Frequently online-only rather than on the shelf
- Costs meaningfully more per bag than PermaSand or PowerLoc
The Bottom Line
The one to order if your joints are wide, your stone is irregular, or you have been burned by haze before. Worth the premium on anything but a simple patio.
DOMINATOR Polymeric Sand
Premium, Standard to Wide Joints
DOMINATOR sits at the premium end of what Home Depot lists, and it earns that position on appearance more than on raw performance. The colour range is broader than the mainstream bags and, more importantly, the colours hold rather than drifting towards a uniform grey after a couple of seasons — which matters when the joint pattern is a visible part of the design rather than something you want to disappear. In practice it is also among the cleanest sands to work with: haze is uncommon even on textured pavers, and the cured joints stay firm without becoming brittle through freeze-thaw cycling. The practical catch is availability. It is essentially an online product in most markets, so it needs ordering days in advance rather than being collected on the morning of the job — which is exactly the situation where people give up and buy whatever is on the shelf instead. If the patio is large, visible, and worth doing once, it is worth the planning. If it is a small utility path behind the garage, the in-store options will serve you perfectly well and save both the money and the wait.
Pros
- Strong colour range that holds up rather than fading grey
- Very low haze in practice, even on textured pavers
- Cures firm while staying flexible through freeze-thaw
- Good coverage per bag on standard joints
- Frequently available for delivery even in smaller markets
Cons
- Almost always an online order rather than an in-store pickup
- Premium pricing that is hard to justify on a small patio
The Bottom Line
The pick when the joints are part of the look rather than just a gap to fill. Order it in advance — this is not a same-day purchase.
What You Are Actually Buying
Polymeric sand is graded joint sand with binders blended through it. Swept into the gaps between pavers and then watered, those binders activate and cure, turning loose sand into a firm but slightly flexible joint. That single change solves the four problems plain joint sand has: it washes out in heavy rain, blows out under a leaf blower, offers weed seeds a perfect seedbed, and gives ants somewhere easy to excavate.
What it is not is mortar. A cured polymeric joint stays slightly flexible, which is deliberate — a paver field is supposed to move a little with the ground beneath it, and a rigid joint would crack. It is also not a structural element: the interlock between pavers comes from the joints being properly filled to depth, not from the binder holding them together like glue. That distinction explains why filling the joints only halfway produces a patio that fails even though the visible surface looks finished.
The colour question comes up more than the chemistry does. In-store bags are limited to tan and grey, which suit most machine-made concrete pavers and clash with a good deal of natural stone. Colour also shifts slightly as the joints cure and again as they weather, so the shade in the bag is not exactly the shade you end up with. If matching matters, buy a single bag first, do a small area at the edge of the patio, and look at it dry the next day before committing to the rest.
3. Joint Width Decides Everything
Every bag states a joint width range, and it is the specification that determines whether the job works. Standard sands cover roughly an eighth of an inch to an inch — the normal gap on machine-made concrete pavers. Wide-joint formulations extend to several inches, which is what irregular flagstone and natural stone need.
Use a standard sand in a wide joint and it lacks the body to hold together across the gap: it cracks, sinks, and washes out. Use a wide-joint sand in a very narrow gap and the coarser grain bridges across the top instead of filling to depth, leaving a void underneath that collapses later. Measure a few joints before you buy, and buy for the widest ones.
| Your Joints | Buy | Where |
|---|---|---|
| Under 1/4 inch | PowerLoc or PermaSand | In store today |
| 1/4 to 1 inch | Either in-store bag | In store today |
| 1 to 4 inches | Gator Maxx G2 | Order online |
| Irregular flagstone | Wide-joint formulation only | Online or hardscape supplier |
4. How Many Bags You Need
Coverage depends on joint width, joint depth and paver thickness, which is why bag figures vary so widely. As a working guide, a 50 lb bag covers 50 to 100 square feet of standard narrow joints on typical concrete pavers. Wide joints or thick flagstone can drop that to 20 to 30 square feet per bag.
Buy one bag more than the calculation suggests. Running out partway through is worse than the wasted money, because the joints you finish later cure on a different schedule and often end up looking slightly different. Our paver sand calculator will do the arithmetic from your dimensions, and covers bedding sand as well.
A related quantity question: the joints need filling to within a few millimetres of the paver surface, not to the top. Fill flush and the sand washes over the faces during watering; leave them under-filled and the joint has no strength. Sweep in, compact with a plate compactor or by tamping, then top up and sweep again before the hose comes out.
What Else to Put in the Cart
The sand is rarely the only thing the job needs, and a second trip mid-installation is how dry surfaces stop being dry. A stiff-bristled push broom does the sweeping far better than a soft yard brush, which skates the sand across the faces instead of dropping it into the joints. A leaf blower — one you can throttle down, or hold well back — is what clears the paver faces before watering, and it is the single most important tool for avoiding haze. A hose nozzle with a genuine shower setting matters more than it sounds, because a jet setting will flood the joints no matter how carefully you work.
For anything larger than a small path, a plate compactor is worth the rental. It settles the sand into the joints far more thoroughly than tamping by hand, which is what lets you top up and reach a properly filled joint rather than a bridged one. Most stores rent them by the half day, and the same machine is what you would have wanted for the bedding layer anyway.
5. Big Box vs Landscape Supplier
For a standard concrete paver patio, the big-box options are genuinely fine, and the convenience of buying sand, a compactor rental and a leaf blower in one trip has real value.
A dedicated hardscape supplier becomes worth the trip in three cases: when your joints fall outside the standard range, when you need a permeable formulation for a driveway designed to drain, or when the colour matters and tan and grey will not do. You will also get advice from people who install this material daily, which is worth more than the price difference on a large job.
The third route is ordering the premium product online for store pickup, which gets you Gator Maxx or DOMINATOR without a separate journey. It only works if you plan a few days ahead, which is the recurring theme of this whole page.
6. Getting It Right on the Day
Polymeric sand fails for process reasons far more often than product reasons, and the process is unforgiving in one specific way: the surface must be completely dry when the sand goes down, and completely clean before the water goes on.
Sweep the sand into the joints with a stiff broom, working diagonally across the pavers so it drops in rather than skating across. Compact, top up, and repeat until the joints are filled to a few millimetres below the surface. Then sweep the faces clean and go over them with a leaf blower on a low setting held at a shallow angle — this is the step that prevents haze, and skipping it is why so many first-time jobs end up with a milky film across the pavers.
Water exactly as the bag directs, usually in several passes with a shower setting rather than one soaking. Watch for water pooling on the surface, which means you are ahead of what the joints can absorb. Our full walkthrough is in how to use polymeric sand, and the failure modes are catalogued in polymeric sand installation mistakes.
When Polymeric Sand Is the Wrong Purchase
Three situations argue against it entirely, and knowing them before you are standing in the aisle saves both money and rework.
A permeable installation. If the patio or driveway was designed to drain through its joints — a permeable paver system laid over open-graded stone — a standard polymeric sand defeats the entire point by sealing the surface. There are permeable jointing products made specifically for these systems, and they are not what a big-box store stocks.
A surface that is already moving. Pavers that rock underfoot, sunken areas that hold water, or a field that has shifted out of pattern all point at a base problem. New joint sand of any kind is cosmetic there. The base has to be lifted and rebuilt, and doing that after sanding the joints means doing the sanding twice.
Very narrow, tight joints on cut stone. Where gaps are barely a joint at all, a fine plain sand often serves better than a polymeric product that cannot reach depth. The alternatives are covered in our polymeric sand alternatives guide, which is worth a look before defaulting to the standard bag.
Pro Tip: Check the Forecast, Not the Sky
Polymeric sand needs a dry surface going down and a clear window of several hours after watering. Rain during that window flushes uncured binder out of the joints and leaves soft patches you will be redoing. A dry morning with showers forecast for the afternoon is not a day to open the bag.
Common Mistakes
Buying the Standard Bag for Wide Joints
The in-store sands top out around an inch. In a wider gap they crack and wash out within a season. Measure your joints before the trip, and order a wide-joint formulation if they exceed the range on the bag.
Not Blowing the Faces Clean Before Watering
Any dust left on the pavers turns into haze the moment water hits it. A leaf blower on low at a shallow angle takes five minutes and prevents the most common visible failure.
Over-Watering
Flooding the joints washes the binder out and onto the surface. Follow the pass count on the bag, use a shower setting, and stop when water starts standing rather than soaking in.
Sweeping It Over Existing Joint Sand
The old sand has to come out to at least an inch and a half of depth first. A thin polymeric crust over loose sand cracks and lifts, usually before the first winter is out.
Buying Exactly Enough
Coverage figures are ranges, and joints are never uniform. One spare bag costs less than the mismatch you get when half the patio is finished on a different day.
Frequently Asked Questions
Does Home Depot sell polymeric sand?
Yes — most stores keep Sakrete PermaSand and Quikrete PowerLoc in the masonry or paver aisle, usually in tan and grey. Premium brands like Alliance Gator Maxx and DOMINATOR are generally listed online for delivery or store pickup rather than stocked on the shelf.
How much does it cost?
In-store bags typically run around $25 to $40 for 40 to 50 pounds, with premium brands ordered online costing more. Compare coverage rather than price per bag — a heavier bag rated for wide joints covers less area than its weight suggests.
How many bags do I need?
Roughly one 50 lb bag per 50 to 100 square feet for standard narrow joints on concrete pavers, dropping to 20 to 30 square feet per bag for wide joints or thick flagstone. Buy one more than the calculation suggests so the whole patio cures on the same day.
What is the best one they sell?
For a standard concrete paver patio bought in-store, PowerLoc edges it on coverage per dollar and PermaSand is equally capable. For wide joints, irregular flagstone, or if haze has burned you before, order Alliance Gator Maxx G2 online — it is the strongest performer in the range.
Is a landscape supplier better?
Often, yes — a hardscape supplier carries the full professional range including wide-joint and permeable formulations, plus staff who install it daily. For a standard patio the big-box bags are perfectly adequate; for irregular stone or a large paver investment, make the trip.
Can you use regular sand instead?
You can, and people did for decades, but plain joint sand washes out in heavy rain, blows out under a leaf blower, grows weeds and hosts ants. Polymeric sand costs more and solves all four. Never use play sand — rounded grains cannot lock up at all.
Can you put it over existing sand?
Not directly. Remove the old joint sand to at least an inch and a half of depth so the new material has body to bond within. Swept over existing sand it forms a thin crust that cracks and lifts within a season.
What if it rains afterwards?
Rain within the first few hours washes uncured binder out and leaves soft, patchy joints. Look for a clear 24-hour window before starting; if rain does arrive early, expect to top up and re-water the affected joints once everything has dried.

The Bottom Line
If your joints are standard width and you are going today, Quikrete PowerLoc or Sakrete PermaSand will do the job perfectly well — PowerLoc gives slightly better coverage per dollar in 50 lb bags. If your joints are wide, your stone is irregular, or you want the best odds against haze, order Alliance Gator Maxx G2 online a few days ahead.
Then buy one bag more than you think, measure your joints before you leave the house, and remember that the product is rarely what fails. A dry surface, joints filled to depth, faces blown clean, and watering exactly as the bag says will make the cheapest bag on the shelf outperform the most expensive one applied in a hurry.
