The 6 Best Pool Plasters

This wiki has been updated 23 times since it was first published in March of 2019. Damage to your swimming pool's surface isn't just unsightly; it can also cause bigger problems down the line, as cracks expand or chips continue to flake away. Fortunately, you can usually perform repairs yourself with one of these handy pool plasters. They're relatively inexpensive, especially compared to the cost of a full refinishing, and they don't require years of experience to use. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.

1. Sider-Crete 20 Pound

A container of Sider-Crete 20 Pound (around $49) should last you quite some time. This beefy bucket has enough product inside to cover 10 square feet, and do it with strength, since it is made with genuine marble for durability. All you have to do is add water and trowel it on.

Dries very smoothly
Won't shrink or crack
Manufactured in the usa

2. Pool Patch Plaster Repair

Each batch of Pool Patch Plaster Repair (appx. $22) features a blend of liquid bonder and pozzolan white cement, a mixture that is specifically formulated for strength. It cures fully in about 12 hours, so your repairs shouldn't keep you out of the water for too long.

Good for covering delamination
Moderately sized 3-pound jug
Easy to work with

3. EZ Products 1 FS

If you're in a hurry, you might opt for EZ Products 1 FS (appx. $28). It boasts a fast-set formula that is ready in just four hours, even in cold weather, so you can refill your pool relatively quickly. Not only that, but you can use it underwater, as well.

Bright white color
Covers a third of a square foot
Simple but effective

4. Atlas Epoxy Putty Set

Technically, this Atlas Epoxy Putty Set (around $12) is not plaster, but if you have small cracks and chips that need attention, it can do the job. You aren't required to do any draining, as it conveniently cures even when completely submerged.

Also for fixing tile
Molds well by hand
Some find it too gray

5. Sider-Crete Combo Pack

You can address a variety of woes with the Sider-Crete Combo Pack (around $49), which includes 3 pounds each of plaster patch, tile grout repair, and tile thin set. To use them, you'll have to lower the water level, but for the quality, it's worth that minor inconvenience.

Packaged well for storage
For divots up to half an inch wide
Homeowner or professional use

6. CGM Perma

Although CGM Perma (appx. $59) comes only in white, you can safely add cement colorants if you need something more lively. And because it uses a high-strength formula with strong bonding properties, you can expect your repair to last for a long time.

Freeze and thaw stable
Great price for the amount
Tough to find in smaller sizes
