United Gilsonite Laboratories manufactures over 80 waterproof masonry paint and other specialty and home maintenance products which are sold nationally and internationally under the Drylok™ and Zar™ brand names.  UGL has come a long way since 1932; meeting new and changing challenges and demands have kept them profitable along the way. By maintaining their emphasis on keeping with the latest technology and market trends they have been able to grow their product lines and uphold their quality.  This was apparent when in 2002, DRYLOK™ Masonry Waterproofer was rated again, for the second time, as America's #1 Masonry Waterproofer by a leading consumer ratings publication.
