Silic8 PS1

Our PS1 primer is a ready-to-use liquid designed to soak in and control suction in many backgrounds whilst still remaining breathable. PS1 can also be used to consolidate and stabilise problematic surfaces and backgrounds and provide additional bond strength before you apply the next coat. Unlike most primers, PS1 contains no plastics  or resins; it is completely mineral, so you wont' smell any odours or breathe in any VOC's.

We know breathability is vital, so PS1 is independently tested for vapour diffusion to reassure you that water vapour will not be trapped in the fabric of your building.
