Rotted wood stabilizer composition and methods of making and using same
View Patent ↗A rotted wood stabilizer composition is provided, the composition comprising: from about 75 to about 90 weight percent of a crosslinking polymer; from about 1.5 to about 0.5 to about 1.5 weight percent of a film forming agent, and from about 8 to about 15 weight percent water, and optionally further comprising a biocide and a defoamer. The composition preferably has a pH in the range of from about 2.8 to about 3.0. Further the composition preferably has a viscosity of between about 750 to about 1250 cps as measured on a BROOKFIELD RV viscometer (helipath on) with a #2 T/E spindle at about 12 rpm and about 25° C. The invention further provides for methods of manufacturing the composition, as well as for methods of repairing a rotted area of a wood component by applying the composition of the present invention.
