Stone surfaces add character to any yard, but they’re more delicate than they appear. Left unprotected, your patio or walkway could end up cracked or stained. Luckily, with the right products and a few simple steps, you can keep them in great shape. Here’s your friendly guide to everything you need to know about sealing concrete, brick and masonry with Thompson’s® WaterSeal®.
 

Stone surfaces may seem rock-solid, but they’re naturally porous. That means they can absorb water, which may cause problems down the line—especially during the freeze/thaw cycles that many parts of the country experience. When water seeps into the tiny cracks and crevices and then freezes, it expands, leading to cracks, spalling (flaking) or white, chalky residue known as efflorescence. Sealing prevents all that, acting like an invisible barrier that keeps moisture out and your stone surfaces looking their best.

Want to keep your outdoor stone looking its best? Follow these steps with Thompson’s WaterSeal for results that last.
 

A clean surface makes all the difference, so give your stone a good wash to get rid of dirt, mildew or any grime that’s built up. Dirt, mildew or efflorescence can prevent the sealer from properly coating the surface. A deep wash using Thompson’s WaterSeal Heavy Duty Deck Cleaner will do the trick. Don’t forget to rinse thoroughly and allow the surface to dry completely.

If you notice cracks or any signs of damage, patch them up before moving on. And if you’ve just had new concrete put down, give it time to fully cure—about 30 days should do the trick. You don’t want to seal it too soon and trap moisture inside.
 

Not all sealants are the same, so it’s worth taking the time to find one that fits your project and your needs. Whether it’s a natural look you’re after or a glossy finish, make sure you’re picking the right product for the job.

For most outdoor surfaces, Thompson’s WaterSeal Clear Multi-Surface Waterproofer is a versatile option that provides moisture protection without changing the surface’s natural look. If you’re wanting a product made specifically for stone, brick and masonry, use Thompson’s WaterSeal Clear Masonry Protector Waterproofer.
 

Whether you use a brush, roller or sprayer, make sure you’re working out of direct sunlight to control the drying process. Spread it evenly, working in sections (~60 sq. ft.). One light coat is usually enough, but if you want extra protection, wait for the first coat to dry (usually 12 hours) before applying a second.

If you’re using a sprayer, be cautious around plants or grass, as the sealant can harm them. Consider using a tarp to protect surrounding areas.
 

After application, allow the surface to cure for at least 24 hours before heavy use. If you’re sealing a patio or pathway, keep foot traffic to a minimum during this time to avoid smudging or uneven drying.

Think of sealing as the start, not the finish. If you want your stone to stay in top form, giving it some occasional TLC is a must.
 

Sweeping away dirt and debris will help keep your sealed stone looking fresh. Stick to nonacidic cleaners if you want to keep your sealant in good shape. Thompson's WaterSeal Heavy Duty Deck Cleaner is a great choice—it keeps your surfaces looking clean and shiny without compromising the protective barrier.
 

Winter can be tough on stone, so take some extra care when the cold hits. Steer clear of deicing salts—they may keep ice at bay, but they can also wear down your sealant and undo all your hard work. Instead, go for sand or other noncorrosive options to keep your walkways safe and slip-resistant without harming the protective barrier.
 

Even the best sealant needs a little love now and then. Thompson’s WaterSeal can handle a lot, but if you want to keep your stone surfaces in great shape, it’s smart to reapply every couple of years. Pay attention—when you see water soaking in instead of beading up, give your stone the attention it needs. 

A little time and effort now can make a world of difference when it comes to keeping your patios, pathways and porches looking their best. With Thompson’s WaterSeal, the whole process is a cinch, and the rewards speak for themselves. No more stressing over water damage or stubborn stains—just a beautiful, well-protected surface you can enjoy year after year. Just follow these steps, steer clear of the common mistakes, and your stone will stay in great shape all year.

Remember: “Protect now, enjoy later.” When you seal your stone surfaces today, you’re setting yourself up for a more beautiful and durable outdoor space tomorrow!
