Preparation of wood before painting
| Properly preparing the substrate is absolutely essential if we want to avoid the appearance of problematic areas on the surface of the wood which could subsequently lead to defects in the durability of the coating.|
The condition of the surface has an influence on the adhesion of the coating - and on the quantity of product consumed.
| Rough sawn timber|
The fibrous structure of the surface of the rough sawn supports provides excellent adhesion. The coating then ages uniformly and exhibits low surface tension and cracking.
| Planed wood|
Coating smooth and planed surfaces consumes little product, although the latter adheres less well. If they have not been properly prepared, the coating tends to flake and crack. Tip: sand the surface before applying the coating.
