It is designed to be applied before Mapei Mapesil AC Silicone when using it on concrete, wood, metal, painted surfaces, plastic and rubber or in case of joints subject to prolonged immersion into water, to promote adhesion of the silicone to the substrate and enhance longevity of the joint.
Mapei Primer FD Silicone Bonding Enhancer is a one component, silicone resin based neutral primer. It is a yellow transparent liquid. It is applied on the joint shoulders so as to obtain a transparent film (absorbent substrates require several coats).

Application: Mapei Primer FD must be applied with a small brush onto the surfaces and left to dry for several minutes to allow the solvent to evaporate. Then apply the desired Mapei Sealant as required. The sealant is to be used as soon as the primer is dry and within the same day.
