Beading vs. Sheeting
|
TThe Beading Myth: The more beading you see, the better your
Twood surface is waterproofed and protected. |
The truth is more beading indicates the applied product is sitting on top of the surface. It tells you it has not permeated. That is why all leading brands of clear and tinted waterproofers suggest you reapply every year. The product does not permeate the surface and is washed away by the elements, or bleached out by the sun.
Products that create beading use wax or wax silicone derivatives that typically last 3 to 12 months. The formation of beads will collect dust and hold a larger volume of water on horizontal and vertical surfaces. Over time this will wear down the surface of a horizontal board due to abrasion. In seams and cracks the beading material will have the same effect with the collection of debris. Later the beading material will retain moisture far longer than the sheeting method of a repellent. This will cause more damage by creating conditions which will optimize bacteria and fungus growth.
Beware of the claim made by most manufacturers that their product penetrates the surface. How can this be so when the wax covering the surface causes beading? Seal-Once is a sheeting type product unlike beading materials. It acts like a car polish maintaining a cleaner surface longer as it sheds water in thin sheets which will not suffer the accumulating effect of beading. For this reason Seal-Once does not contain any beading additives.
