PH test

The steps for performing this test are seen below:

 

1 -. Clean the floor to remove all oil, dirt, dust or any coating / sealer soil. If the surface has a primer, sealer or old adhesive that may affect the test procedure, must be removed, either sanding or washing. Remember, the alkali is present in the cement, the removal of more than 1/8 "can give a high pH reading. This test is designed to evaluate the surface that comes into contact with the adhesive.

 

2. Pour a small amount of wash water (ca. 1 1/2 diameter) in the floor surface.
