How do I use SILRES® WH?
SILRES® WH is usually diluted 1:4 to 1:9 with water for direct application to wood. SILRES® WH can also be added undiluted to waterborne stains in concentrations of up to three percent.
Does SILRES® WH allow for reduced use of biocides?
Yes. Using SILRES® WH provides long-lasting protection from water and from the damage it causes. That allows for reduced use of biocides, especially fungicides. In the case of many biocides, it eliminates their use entirely.
Can wood be painted after it has been impregnated with SILRES® WH?
Wood treated with SILRES® WH can, in principle, be painted if some weathering of the impregnated substrate is allowed first. However, one thing needs to be remembered: smooth wooden surfaces will absorb only some of the silicone – the rest remains on the surface. As a result, and especially in the case of highly concentrated wood preservatives, paint adhesion may be restricted and leveling impaired. For this reason, SILRES® WH should not be employed as a primer.
Will beading be visible right away?
Yes, but the beading effect becomes best visible after the treated surface has been exposed to the elements for a while. With SILRES® WH, however, beading will then be visible for an unusually long time.
Does SILRES® WH keep wood from graying?
No. SILRES® WH does not prevent graying, because this is caused by UV radiation, and silicones are transparent to UV radiation. SILRES® WH does, however, help make graying uniform.
