Monneli Primer A 16

Synthetic Resin Primer

Uses
PRIMER A16 is used for the preventive treatment prior to laying of ceramic tiles with the cement adhesive on gypsum boards. Such application on the supports avoids the chemical reaction between the gypsum sulphates and the cement aluminates contained in the adhesives for ceramic tiles, which in case of humidity presence could provoke breakaway of tiles.
It can be also used at gypsum or very porous supports before painting with acrylic or vinyl paints, to avoid too fast drying.
PRIMER A16 is used on light weight plaster and other porous surfaces such as asbestos boards, on wood, hardboard, chipboard, and so on, before fixing ceramic wall and floor tiles in the usual way.

Technical Information
Product Description

PRIMER A16 is a water based synthetic resin with high penetrating power. Once applied on the surface it dries forming a transparent and compact film. The film has a function of protective barrier, which improves the support's absorption against liquid and it improves the adhesion of ceramic tiles, paints, wallpapers, plasters, etc. to the surface.

Advantages
  • As an anchoring coat over gypsum plaster
  • Improves adhesion of smoothing compounds, paints, adhesives for wall papers, adhesives for tile mortar, and mortars for render

Consumption: 0.1 – 0.2 Liter / m² depending on the porosity of the surface.
