United Gilsonite Laboratories has been in the market since early 1932 and prides itself to be among the pioneers of waterproofing technology. Their products are sold products both nationally and internationally at hardware stores, home centers, paint stores and lumberyards.

DRYLOK Extreme Latex Water proofer is the US market’s number 1 rated water proofer. It can be used to stop water leaking through any bare masonry surface, vertical or horizontal (not subject to foot traffic). It is tested to stop hydrostatic pressure, up to 15 PSI (a wall of water 33 ft. high) or wind driven rain (up to 98 mile per hour). DRYLOK Masonry Waterproofed is versatile; it can be used on retaining walls, stucco, fountains, swimming pools, waste water management structures, elevator shafts and more.

With over 15,000 dealers nationally and internationally, there is always a UGL salesperson nearby. Their sales team consists of direct salespersons who work one-on-one to provide their dealers with the best products and service available in the market.

They also produce ZAR Deck & Siding Solid Color Exterior Stain which is specially formulated using Dual Resin technology. Containing 100% acrylic resin and a unique alkyd blend, ZAR Deck & Siding Stain is ideal for use where the natural texture of wood is to be accentuated. It shields and protects against the damaging effects of sun, rain and salt air.

What sets them apart from their competitors is that they consider proper preparation and application instructions when manufacturing and in the usage of their products. These products hold up to heat extremes, UV rays, and tropical storms.
