How to Use DRYLOK Wet Wall Bonding Primer

Preparing the Surface

Before applying the primer, it’s critical to thoroughly prepare the surface. To get a better result, it is important to adequately prepare the wall surface by eliminating any paint that is loose or peeling and repairing any cracks or holes that may exist. This will ensure that the surface is in good condition and as smooth as possible, to allow the bonding primer to work effectively.

Cleaning and Degreasing

Cleaning the surface is an integral part of the preparation. You must remove all dirt, grease or oils from the wall as these substances can interfere with the primer’s ability to bond to the surface. Use a mild detergent or a specialized cleaning solution and rinse thoroughly to ensure that the surface is absolutely clean.

Sanding and Smoothing

For optimal results, sanding the surface to create a smoother texture is advised. This will help the primer adhere better and will enhance its overall performance. Make sure to dust off any residues after sanding.

Application Process

Gathering Materials

Before you begin, gather all the necessary materials. This includes DRYLOK Wet Wall Bonding Primer, paint brushes or rollers, a paint tray, sandpaper, cleaning materials and protective gear such as gloves and safety glasses.

Apply the DRYLOK Wet Wall Bonding Primer

Start the application process by pouring the primer into a paint tray. Then, using a brush or roller, apply the primer evenly across the surface and ensure that all areas are adequately covered. Carefully follow the manufacturer’s instructions for best results.

When it comes to dealing with wet-wall applications, DRYLOK Wet Wall Bonding Primer has exceptional utility. The primer can be applied to a wall that is wet, but not actively leaking. However, in the case of seasonal leaking, the application should be done during a dry, rain-free period. If the wall is continually leaking, the primer can still be used following a specific procedure. 

First, drainage holes should be drilled at the bottom of the wall to release the water. Next, the holes need to be patched up with DRYLOK Fast Plug. Finally, the Wet Wall Bonding Primer can be applied to a properly prepared surface.

This product can also be applied to floors for added protection. However, the final topcoat needs to be a product that is formulated for horizontal foot traffic, like DRYLOK Latex Concrete Floor Paint.

Drying and Curing

Allow the primer to dry a minimum of 1 hour for a single coat application. Before applying a second coat, you should wait a minimum of 2 hours. Curing times may vary depending on temperature and humidity levels. Ensuring the primer has properly dried before applying your topcoat is vital for achieving a long-lasting, high-quality finish.

Clean-up and Maintenance

Clean your tools promptly after use, using soap and water. As for maintenance, it’s recommended to check the condition of the paint periodically and apply a new coat of primer and paint as necessary.
