Sandstone Adherence in Building Construction
This study analyzes bonding properties of porous sandstone to conclude that adherence between porous sandstone panels and their background supports, in building construction, can be substantially improved by applying adhesive primers at the rear of the panels. Two types of primers have been studied: styrene-butadiene latex and epoxy-resin. Laboratory tests have shown a bonding strength increase by applying both products. However, styrene-butadiene latex primers have shown better performance than epoxy-resins, mainly after accelerated ageing cycles. Bonding joints based on styrene-butadiene present higher strength than natural sandstone under tensile pull-off and shear tests; this higher strength was retained after ageing cycles of wet-dry and cold-heat on the samples. This new technique offers an innovative use of natural porous sandstone in building construction and in architectural heritage restoration, allowing for thinner veneers, substituting today's heavy thick panels. Commonly used epoxy-based mortars and latex-based mortars were discarded in this research as described in text.
