It is recommended that SAM® MDF mouldings are allowed to remain in the fixing environment for approximately 24 hours before use. It is recommended not to fix SAM® MDF mouldings to damp plaster or any other damp materials and to avoid high humidity conditions.

SAM® MDF Mouldings should be stored on dry bases and under cover. They should be fully supported on a flat level surface with ample ventilation provided to reduce the risk of absorbing moisture. Any protective wrapping should be left in place until time of use.
Please note that exposure to direct sunlight can (as with solid woods) lead to discolouration.

Before being fixed in place, any cut edges or other unsealed areas should be carefully sealed by the fixer with at least one coat of proprietary wood primer complying with BS 5358 or one coat of polyurethane or acrylic varnish.
When cutting or mitring wrapped product, use a fine tooth saw and cut from moulded face into the profile to avoid excessive rough edges and fibres occurring on the visible surface.
SAM Mouldings recommends the use of adhesives and as with primed MDF, most modern glues and panel adhesives work well, but manufacturers' recommendations should be followed in cases of porous damp surfaces. Caution is advised to avoid overspill of adhesive onto the face of the moulding as the veneer could be stained.
If using nails for fixing, they should be punched in below the surface and not inserted nearer than 12mm from any edge and at maximum 900mm centres. For nailing through a moulded profile, lost head pins are recommended and caution is advised to avoid danger of surface damage when nailing . For door framing, It is helpful, but not essential, to drill prior to fixing.
Linings should be fixed at maximum 600mm centres.

Any visible nail or counter-sunk screw fixings should be filled using a good proprietary quality shrink resistant non-water based filler suitable for the wood species being used. Alternatively, solid wood plugs again matching the wood species may be used. The filled area should then be sanded smooth with a fine abrasive paper (grit range 320-600) prior to staining / finishing.

When varnishing, check with a finish manufacturer. Polyurethane or an acrylic woodstain varnish / lacquer are a good choice when finishing your mouldings as they have excellent moisture and vapour resistance. Water based stains and finishes are not recommended for finishing wrapped veneer product.
Please note that when varnishing / lacquering, the veneered surface may darken substantially in colour.

Please note that real wood veneers are a natural timber product therefore colour variations may occur between batches of veneers
Due to the high level of tanic acids in some woods such as oak or cherry etc, a black stain may be formed when the veneered surface gets wet or damp or reacts to detergents.
