Generally speaking, exotic wood does not require any particular product to be washed. Probois uses conential shampoos and soaps in the majority of its projects. Indeed, since exotic wood often has very small pores, dirt and other impurities often have a more difficult time penetrating them. Cleaning it with a pressure washing machine is very effective since the dirt is often found on the surface of the wood and not within it.
An all-purpose brightener is used during the neutralization process. A ratio of 10% is always respected to make sure we do not alter the characteristics of the wood and its colors. Afterwards, we leave the wood dry for a day to make sure all surfaces have dried adequately. Note that, the smaller the pores of the wood the faster it will dry since water has a more difficult time penetrating it.
Since the exotic woods that are used in Quebec to design all manner of structures are often imputrescible, it is necessary to use a large grit during the sanding process. Thus, PROBOIS uses grits between 40 and 60 in the majority of its projects. In this way the pores of the wood are opened in the most efficient and optimal way.
Note that if the surfaces are inadequately sanded it will immediately show once the oil or stain is applied. Indeed, since the oil or the stain will not penetrate the wood uniformely some parts of the wood will be darker while others will be paler. Once again, a good prepartion is the secret to a good finish and a job well done. Once the surfaces are sanded we clean them with acetone or methyl hydrate.
