Grades & Finishes

Vis2
Visual - Appearance A

This grade is intended for use in applications where appearance of the member is important and clear or painted finishes are used. All surface voids are filled, small tight knots are permitted. The surfaces are planer machined to a high quality finish

BSF
Bandsawn

This is only supplied in the visual grade as its used for rustic visual appearance. The roughness of the bandsawn finish may vary slightly between batches.

SS
Sanded and Sealed

This is a premium finish added to a visual product, where all blemishes are filled, the whole product is sanded and then coated with a sealer that will protect the product from ingress of moisture for 6 weeks. This sealer is not a long term sealer. The product must be sealed for the long term as per our painting/sealing requirements.

PP
Preprimed

This is a primary coat that is applied in our factory as a protective coat to stop ingress of moisture until the undercoat and top coats are applied. This primer coat is not to be used as the final finish and the product must be sealed for the long term as per our painting/sealing requirements.
