How to Prepare for Applying Basement Waterproofing Paint

Before you apply basement waterproofing paint, there are several steps you should take to prepare the surface properly. 

  • The first step in the process is to clean and tape your walls. You will want to remove any debris and clean the surface so that the waterproofing paint can adhere properly. Ensure that the surface is free from any magnesium deposits or efflorescence. We also offer a wide range of detergents to clean off any dirt.
  • Once your walls are clean, use a putty knife to create a smooth surface by taping off the edges. This will give you a nice, clean edge when you apply the paint. 
  • Next, you’ll want to fill in any cracks and holes in the wall with a filler. This will create a smooth and even surface for the waterproofing paint to adhere to. 
  • When you’re ready to apply the paint, be sure to choose a high-quality product that will last for years to come.

Applying Basement Waterproofing Paint

There are a few steps to follow when applying basement waterproofing paint: 

  1. First, you’ll want to cover the floor and equip yourself with the appropriate safety gear. You don’t want to get paint on your hands, so you’ll want to use gloves and a drop cloth, too.
  2. Next, load your paint roller with the appropriate amount of paint. 
  3. You’ll want to apply a thin coat of paint to ensure a proper seal. You don’t want to apply too much paint, as this can create a sticky and difficult-to-clean surface and this would also cause delays in drying and re-coating times.
  4. Once you’re ready to apply the paint, roll it along the wall in smooth, even strokes. Make sure to apply the paint to all areas, including corners and edges.
  5. Apply 2-3 coats to any vertical surface for optimal results.
