Under thasa conditions, bonding should not ba attempted unless special slow-drying solvents ara used. Water-based adhesives are not recom mended for usa under these conditions. X Bonding Whan Surfaces Ara Over-dry or Under-dry--Cara should bo taken to follow tha manufacturer's recommenda tions concerning the usable tack range of the adhesive. If assembly is made before the adhesive is dry or after the allowable open time is exceeded, an unsatisfactory bond will result 1-21-1964. LD1-7.03 COKES There are a variety of core materials which are satislaetory for use under decorative laminates. Some acceptaoie materials include plywood, ftakeboero. wood composition board, inorganic fiber board and metal. These have a wide variation in physical properties and every precaution ahould be taken to insure proper selection for the intended use. P/eifer board, gypsum board, plaster and similar mstsrisis are noi recommended beesuss f/ieir imsrnsi bond strengm is nor sufficient lor this service. When plywood is usad. it should have a face of close-grained wood to avoid tne reproduction (telegrapning) of a pro nounced wood gram effect on the surface of tne laminata. Urea-bonoed plywood >s sufficiently waier resistant lor ordinary service. Exterior-grade plywood should be used for applications where moisture may bo prevalent (drainbosrds. ate.). All wood-type core materials should nave the optimum moisture content (depend ing upon local conditions) in order to minimize telegraphing and warping tendencies.

LD 1-7.04 WATERPROOFING In conatructiona where the cere material Is exposed and water ia encountered (e.g.. around sinks), it is recommended that the matching surfaces and edges of the decorative laminate and eora be given a waterproofing treatment prior to installation of the trim.
