This research aims to study the shear strength of species-adhesive-moisture-waterproofing combinations and delamination of Glued Laminated Timber (Glulam) made with Paricá (Schizolobium amazonicum Herb) and Lyptus Wood species, using two different adhesives, the bicomponent resorcinol-formaldehyde based adhesive (CASCOPHEN RS-216-M) with catalyst FM-60-M and the bicomponent melamine-urea based adhesive with catalyst AkzoNobel MUF 1242/2542, both in a proportion of 100 parts/adhesive mass and 20 parts/catalyst mass and waterproofed by the commercial product ProtectGuard. Shear strength tests in adhesion line were performed according to North American Standard AITC 190: 2007 and delamination tests were carried out obeying Canadian Code CSA 0177: 2006. The results show that average values of great shear strength were obtained in tests on the glue line of the specimens treated with the waterproofer, however, within them, the timber was dry. Lyptus Glulam beams did not present a performance in delamination that was compatible to external applications, but Paricá beams are fit to this use, once they are previously treated.
