Most concrete sealers when properly installed and cured will be completely chemically compatible with Seal Bond 95 and Seal Bond 220 Adhesives. The real question is how will the system (which is comprised of the actual concrete floor, sealer, adhesive and specific pedestal) perform relative to the engineering specification of a particular project. If sufficient force is applied (Overturning Moment Test) will the adhesive be stronger than the coating to the concrete and pull the sealer off the floor? Since there are literally hundreds of sealers on the market the only answer is to test the actual components for each job (yes, concrete varies). In many cases, adhesion of the Seal Bond Pedestal Adhesive can be improved by scuffing the floor sealer. This activity will modify the surface of the sealer and promote anchoring of the adhesive.

Common concrete sealers used in Access Flooring can be divided into at least three categories. The first, “film forming” sealer form a continuous membrane on top of the concrete. A lot of concrete sealers are “penetrating” meaning that they go down into the concrete rather than form a film on the surface. When Seal Bond™ Adhesive is applied over a penetrating sealer it can bond to the surface of the concrete (preferred) rather than to the membrane which is present with a film forming sealer and be dependent on the sealers bond strength to the concrete. A third category would be two-part epoxy coatings. Seal Bond 95 adheres well to most but not all epoxy coatings and Seal Bond 220 should always be tested when using Epoxy.
