Non-Porous Primers

Prime & prepare non-porous surfaces for mastic sealant application  Primers play a key role in assisting the effectiveness and longevity of mastic sealants. Non-porous primers are specially formulated to be compatible with most smooth, non-porous surfaces such as glass, glazed ceramics and certain plastics. These specialist type of primers are made using special adhesion-promotion agents that penetrate the non-porous surface, creating a slightly rough texture that greatly enhances the bond strength of the sealant. Non-porpous primers work by preparing the surface, promoting adhesion, improving performance and in some cases (particularly when using silicone) work as a barrier ...

Prime & prepare non-porous surfaces for mastic sealant application  Primers play a key role in assisting the effectiveness and longevity of mastic sealants. Non-porous primers are specially formulated to be compatible with most smooth, non-porous surfaces such as glass, glazed ceramics and certain plastics. These specialist type of primers are made using special adhesion-promotion agents that penetrate the non-porous surface, creating a slightly rough texture that greatly enhances the bond strength of the sealant. Non-porpous primers work by preparing the surface, promoting adhesion, improving performance and in some cases (particularly when using silicone) work as a barrier to prevent staining or discoloration of the substrate where the silicone sealant often reacts. The use of non-porous primers is highly recommended by manufacturers for certain applications and care should always be taken to test a small area before carrying out a large application. Always check with the manufacturer before the use of a non-porous primer.
