What Are The Drying And Curing Times For Drylok?

Most Drylok formulations have the same drying and curing times. Drying is the solvent evaporating the water and becoming ready for another coat. Curing time is the recommended length of time before the formulation is ready for daily use.

For many Drylok waterproofer formulations, the drying time between the first and second coats will be two to three hours.

After the second coat, you should let the Drylok cure for a minimum of four hours before subjecting it to light foot traffic. It needs a minimum of 24 hours of curing time for heavy foot traffic.

In terms of subjecting Drylok to heavy machinery or vehicles, you should let it cure for at least a week before driving on it. This ensures that all fumes and volatile solvents have completely evaporated and the formulation has completely set on the masonry.

Failure to follow recommended curing times for Drylok can compromise its effectiveness and significantly decrease its longevity.

How To Get The Best Results When Applying Drylok

Achieving the best results with Drylok does not come by chance. There are proven steps that will affect the outcome of your application of the product. To use a cooking term, you should always follow the recipe when using Drylok.

Preparation Is Key

On any masonry project, preparation is critical. It can make or break the whole process.

To start, remove all the loose dirt and particles that could keep the Drylok from properly adhering. Clean the entire surface with a wire brush.

If you see a white powdery substance when preparing your wall or floor, be sure to remove it, as it is a mason's worst enemy. This powdery substance is called efflorescence.

It's a buildup of salt that emerges through the surface of concrete. In some cases, severe buildup of efflorescence can signify compromised structural integrity.

Prior to the actual application, remove all traces of efflorescence to avoid compromising the effectiveness of a product such as Drylok Masonry Waterproofer. You can use Drylok Etch to neutralize the efflorescence.

Patch Every Crevice

The second step is to patch every crack and crevice present. Any moisture that seeps into the masonry during application can compromise the overall effectiveness of the waterproofer.

Patch every wall joint and corner, as these areas are the most susceptible to water leaks and moisture. You can use Drylok's hydraulic cement for this procedure, as it sets in just five minutes after application.

Waterproof Everything

For the final step, apply your Drylok waterproofer of choice. Ensure even application on the entire surface and fill in every nook and cranny.

Depending on the waterproofer formulation you choose, you can apply it to the floor for a complete masonry seal.

As it cures and dries, Drylok expands into the pores of the masonry, creating a complete seal while also becoming part of the wall.

Is A Second Drylok Coat Necessary?

Applying a second coat is essential for Drylok to work correctly. It covers and reinforces all areas of the first coating. It acts as a seal and barrier while also making the final product as even as possible.

Also, a minimum of two coats is required for the limited warranty of Drylok waterproofer to be applicable. So, be sure to follow the recommended coating application procedure to get your money's worth from Drylok. 

How Long Will Drylok Last?

According to Drylok, when the correct procedure is followed during the application process, Drylok can last for more than five years. Effectiveness will vary depending on what type of Drylok you apply.

Drylok works well with porous materials often invaded by moisture, leading to cracks and deterioration. Terra cotta is often left outdoors to face the elements, and Drylok can help limit damage due to differing weather conditions.

Outdoor Fire Pits And Ovens
