Exterior Technical Information
Whilst originally designed for interior decoration, our products have become an increasingly popular choice for external use, being impervious to moisture and rot-proof. However, all finishes tend to fade from the effects of sunlight, especially stain finishes, and our's are no exception, and whilst many customers find this 'weathered' look attractive, it is likely that the finish will need refreshment at some stage. This is more for appearances than protection, as OCR will neither rot, nor absorb or emit moisture (often the cause of peeling or cracking paintwork on real wood). As a result, maintenance should be an infrequent requirement, especially with paint finishes, and replacement due to rot, unnecessary.
(Jacobean Oak finish after 12 years of 'weathering')
OCR (Oakleaf Cellular Resin), a specially formulated resin-based moulding material. The closed cell structure of the material is inert once moulded, so neither absorbs nor emits moisture. Can withstand temperatures of up to 100 degrees centigrade, beyond which surface blistering might occur.
Our planks are supplied in approx 75, 100, 130, 150, 170, 200 widths (mm) x 15-25mm thickness, all 3m in length, with moulded/presentation face and edges, and flat, non-presentation backs.
Jacobean oak, achieved through the hand-application of wood stains to a painted surface, to which a top coat of lacquer is applied, creating an antiqued effect. All solvents used in the finishing process have fully evaporated prior to packing and despatch. Non standard finishes, including black paint, together with a matching service, are also available for a small additional charge, or orders can be supplied in a primed state, ready for painting.
The density is approximately 100kgs/m3.
Being closed cell, the moulding material is virtually unaffected by weather. However, it is important to protect the cellular core from sunlight, so cut ends should be sealed with filler or paint, or concealed by butt joint.
Sharp, small-toothed woodworking tools are recommended for use during installation, in conjunction with a pair of wall plugs and screws every metre or so, the latter counter-sunk just beneath the surface and concealed using our mock oak pegs. A solvent-cure filler adhesive is recommended in addition, to minimise any small movements. Unless securely fixed, the product will be free to bend and twist, much like real wood. As with wood, dust masks and eye protection are recommended when cutting.
A small amount of expansion/contraction should be expected from the effects of heat, but none from the effects of moisture.
