4. Keep your eye on the forecast. You will need 24 – 48 hours of dry weather after applying the sealant. Make sure the forecast doesn't call for rain.
Curing Time
Customers must also allow at least a 24-48 hours of dry weather after sealer has been applied. If the sealer is not cured correctly, water can cause white marks or stains on your pavers and can even be trapped beneath the layer of sealer.
If you experience any dew, accidental sprinkling of water or rain as the sealant dries, the sealant can become stained, cloudy, blotchy, or discolored and it will no longer be aesthetically pleasing. Simply don't seal your paver if there is even a remote chance of rain, fog, or a drizzle.
How long do I have to stay off my pavers after they are sealed? Vehicles must stay off the sealed areas for 48 hours minimum. Foot traffic is generally ok after 3-4 hours.
A heavy downpour will devastate a freshly-sealed pavement, and a shower will often cause intense 'spotting'. Even a light drizzle can, and often does, cause a milkiness to the finished result, and there have been cases where an overnight fog, mist, or dew has wreaked havoc.
You will need 24 – 48 hours of dry weather after applying the sealant. Make sure the forecast doesn't call for rain. 5.
Give the sealer at least 4 to 8 hours of drying time before rain is expected. Don't drive on your newly-sealed interlocked driveway for 24 to 48 hours after applying the seal. Give your sealed driveway or interlocking walkway at least 6 hours to dry before walking on it.
What are the ideal weather conditions for sealing? Ideal conditions would be 75 degrees and sunny; however, anywhere between 50-90 degrees is generally fine. Take note that solvent-based sealants evaporate faster, so lower temperatures are better for application.
You pressure clean the pavers, re-sand the paver joints and then apply two coats of your favorite paver sealer and the job was complete.
Decreased Drying Time: Properly sealed pavers do not allow water to absorb inside them. This significantly reduces drain time. Pavers that dry more quickly, are much less likely to support mold and algae growth or develop efflorescence.
Choosing to seal your pavers will keep your color consistent and un-faded. Not only does choosing to seal your pavers keep the color untouched, but it can also increase the vibrancy of your colors. One largely agreed upon benefit of sealers is that they limit stains.
Efflorescence is also known as calcium hydroxide or free lime. The phenomenon of efflorescence occurs when water soluble salts migrate to the surface of the paver with the help of water (i.e., condensation, rain).
Remove the tarp as soon as the rain is done so the air can assist in the curing process since PolySweep needs to dry fully to be cured. A hard rain on polymeric sand that has not set up properly could result in sand all over the tops of the pavers.
After your pavers have been sealed, it's a good idea to let the sealer fully cure before walking/driving over it. If your sealer was in a driveway it's best not to drive over it for at least 48 hours. You'll know the pavers are ready for activity when the sealer is no longer sticky or tacky.
Black Diamond Coatings recommends a combination of both a sprayer and a roller. To truly be a Paver Whisperer, you must make sure the sealer is applied evenly to the surface. Using the spray technique and back rolling any puddles will result in a smoother application and a smoother finished product.
Pressure Washing: Start by having the whole area pressure washed before sealing pavers. Grime and dirt can inhibit the paver sealant from penetrating. As a result, the paver stones may start pitting, and discoloration can happen. You are also likely to seal dirt beneath the coating.
Never Too Late to Seal Pavers
It's always best to seal soon after a new installation. But, our proven system of repairing, cleaning and sealing will also bring back the original luster to old, dirty and fading pavers. Sealing is the final step in a comprehensive process.
There are three ways to darken your pavers: sealing, staining, and painting, with the first being the less invasive option. The first thing you need to do before starting any process of darkening pavers is to clean them.
If your pavers have been sealed, which is a service that we offer, it's a lot easier to maintain and it does slow down mold growth for the simple fact that when your pavers are unsealed, that moisture will sit in the joints and make mold grow. Mold likes damp, dark areas.
Sealers make bricks shine. Last, but not least is the sheen. Our sealers that we use at Paver Protectors offer a nice sheen and most companies have additional sheens available as do we. Our water-based sealers that enhance the color, they also enhance the sheen.
If it rains and the acrylic hasn't had a chance to cure, it will delaminate, and you will end up with white blushing and hazing throughout the sealed area. If you used a water-based acrylic, the delaminated coating would have to be removed using a coating remover like the Armor CR100, and then re-applied.
This usually goes away in a few days, but the bigger problem is that the product will take on a milky white appearance every time the sealer gets wet. The sealer will turn back to clear once the moisture has evaporated, and this oddity seems to have no effect on durability.
A: Most sealers dry fairly quickly and are usually touch-dry after 4 hours. This is true of both penetrating and topical sealers. Penetrating sealers usually fully cure in 24 hours with topical sealers generally taking up to 48 hours to fully dry.
