Eternit Primer


Product description:
Eternit Primer is a water dilutable pigmented primer based on acrylic dispersions.

Product properties and use:
Eternit Primer is used as primer on fibre cement roofs. It is especially suitable for rather old, very absorbent roof plates. The primer penetrates into the fibre cement plate and ensures good adhesion of the topcoat, applied subsequently.

Eternit Primer always has to be coated with Isonit or Rubber, subsequently.
Rubber is especially recommended for degraded primed fibre cement plates.
