Step 1 – Moisture Test

It is important to know the condition of the floor surface. So, it is recommended to test the floor for moisture vapor transmission per ASTM D4263 standard, no less than 16 hours before you begin your project. Follow these steps:

  • Cut a 1.2 mil or 1.5 mil plastic sheeting into an 18" by 18" square

  • Assure the floor surface and plastic sheeting are within the manufacturer's recommended temperature for the coating product

  • Tape the plastic to the floor surface (do not apply in an area that receives direct sunlight)

  • Wait a minimum 16 hours and lift the plastic

  • Check the area for moisture

After waiting the recommended period, lift the plastic. Look for moisture on the underside of the plastic or for the surface of the concrete to be darkened. If either of these occur, the surface is considered too wet for a coating application. If the floor passes the moisture vapor transmission test, proceed to Step 2.

Step 2 - Cleaning the Floors

It is necessary to know how to clean basement floors properly to ensure the coating product will adhere to the floor surface. On both old and new surfaces, preliminary work may be necessary to provide a porous surface for the coating product to adhere. The proper surface will feel textured, like fine sandpaper. Follow these steps.

  • Rough up the surface with sandpaper or a grinder to prepare the floor surface

  • Thoroughly clean the floor surface with a degreaser, like PPG DuraPrep Concentrated Degreaser

  • Tape areas to be protected with a masking tape or safe release tape, like 3M tape
