Overlaying

Riga Preprime is overlaid with a preprimed painting film, which is hot-pressed onto the panel surface. The reverse face can be overlaid with the same painting film, phenol film or raw plywood in various grades.

Painting instructions

The Riga Preprime surface is created with the application of a thermoset acrylic latex primer topcoat that is compatible with the use of standard latex, alkyd and oil-based paint

Surface properties

The surface is homogeneous and even, paint consumption is reduced, and paint cracking is avoided.

Edge sealing

The edges are sealed with colour-matched moisture-resistant paint.

Other colours are available upon request.

Gluing classes

Riga Wood birch plywood is glued with weather and boil-proof phenol-formaldehyde or lignin phenol formaldehyde resin adhesive according to EN 314/Class 3 Exterior. Bonding with moisture-resistant low-emission melamine-urea-formaldehyde resin is possible according to EN 314 / Class 1 and BS 1203 / H1.
