Product
Birch plywood (Riga Ply) overlaid with multi-layer phenol film on both the sides. The wear side has a smooth wire mesh pattern (WH); the reverse side normally is smooth, although it can have wire mesh pattern, too. Riga Smooth Mesh wire mesh overlay is decorative and withstands hard wear.

Applications
For walls and applications where high wear resistance and/or decorativeness is required.

Advantage
The smooth wire mesh surface has high resistance to wear, it is decorative, weather and waterproof, resists to commonly used chemicals, it is easy to be cleaned. Environmentally friendly.

Gluing classes
Plywood is glued with waterproof phenol formaldehyde resin adhesive. Bonding is resistant to weather and boiling water. It meets requirements of the following standards:

EN 314 / 3rd class;
BS 1203 / H4 (previously WBP); 
DIN 68705 Part 3 /
type BFU 100.

Formaldehyde emission
In accordance with the standard EN 13986 formaldehyde emission meets the Class E1 requirements. Test method EN 717 Part 2.

Overlaying
The panels are overlaid with a phenol film and have smooth wire mesh pattern imprinted during hot pressing process. The unit weight of Riga Smooth Mesh plywood film is 120g/m2 or 220g/m2.
On special request, panels can be overlaid with multi layer phenol film thus giving superior wear resistance of overlay. The overlaying film can be the same on both sides or it can differ. Wire mesh pattern can be of two kinds:
          Large Mesh - 2.5 mesh per 1cm;
          Small Mesh - 4.5 mesh per 1cm.

Edges sealing
Edges of the panels are matched with the face against absorption of moisture by using acrylic paint.
Other colours are available and the edges may be unsealed at customers' request.

Overlaying characteristics
Overlaying surface is smooth, glossy and hard. It withstands abrasion, it is weather and moisture proof and resists commonly used chemicals, dilute acids and alkalis. The surface is easy to clean with water or steam wash.
Abrasion resistance according to the Taber test (EN 438-2): depends on applied film, surface texture*, conditions of product storage and application, thickness of film (see below) a.o.

Small mesh resistance to wear parameters are better than Large mesh ones. It is possible to obtain overlaid plywood resistance to wear even above 10 000 revolutions.
