Timber is a living, breathing organism and has to be maintained for its lifetime, especially in our harsh South African climate. Luckily looking after you mouldings, skirting, beams, shelving, doors, frames, decking, flooring, etc. is easy.

Always store the material in a cool, dry, well ventilated area where it will be protected from the elements such as damp, rain and direct sunlight.

Never lay the products flat on the ground as it will cause twisting, warping and bending as the timber absorbs the moisture from the ground if untreated. Instead raise it with dunnage (loose material) to protect it from rising damp?.

Turn stock frequently (every 2 weeks – max) to prevent cupping. This is especially true for shelving.

Mouldings, specifically pine, should be kept in bundles for as long as possible to prevent bending and warping.

Doors should be stacked on a flat surface with dunnage and not directly on the ground. Avoid storing them on their edges/ends. Treat all six sides as soon as possible.

Once an item has been installed, make sure to treat it with a reputable treatment. Refer to manufacturer's recommendations and intervals of treatment.

Breadboards should routinely be treated with vegetable or olive oil to keep it from cracking or splitting.

Disclaimer: RSB (Pty) Ltd. cannot accept any returns where the products have not been stored as above or looked after according to our recommendations. All stock has to be returned within two weeks of delivery.
