Water-repellent finishes. The early water-repellent finishes were all based on the application of a mixture of waxes, which were pliable at normal temperatures, applied to tightly woven cotton fabrics.

These were, of course, well suited to sail cloth and protective clothing, but problems were encountered when the garments were cleaned.

Preservative treated wood or naturally durable wood (eg. cedar) must be used for exposed decking, posts.Water repellents (WRs) and water-repellent preservatives (WRPs) are penetrating wood finishes that increase the durability of wood by enabling the wood to repel liquid water (Fig.

2). This ability to repel water is imparted by a wax, an oil, or a similar water-repelling substance.You can use soap and water to clean-up. WOODRx lasts times longer than traditional sealers and is durable in all climates.
