Application

Surface preparation

A minimum of preparation is required; a good sweep to remove surface dust and dirt is often sufficient. The surface must be dry and porous to allow the Universal Sealer Dustproofer to penetrate. Oil and grease can be removed using Watco Bio D (or similar degreasant), the floor must then be rinsed with water and allowed to dry. If there is doubt that the subtrate is absorbent, pour some water onto the surface. If the water is easily absorbed, the surface is suitable for treating with Watco Universal Sealer Dustproofer. New concrete should not be treated until the surface is sufficiently dry to absorb the solutions (usually at least 7 days in good drying conditions). For more information click here. 

Application

Apply between 10°C – 30°C only. Pour directly onto the floor from the container. Use a soft broom to distribute the solution, working it well into the surface. Ensure that the surface has absorbed as much solution as it can. Avoid ponding, i.e. do not allow any surplus unabsorbed solution to remain and subsequently dry on the surface. Use the broom to sweep any excess solution onto adjacent areas. One coat is normally sufficient on average quality concrete. A second coat may be required on exceptionally porous substrates. Allow the surface 12 – 16 hours to dry before making a second application.
