Original Abstract

The authors focus on the possibility of sealing wooden elements. Wood appears to be a problematic substrate, and in some cases it could be necessary to solve problems through the use of sealants. The research is based on the test procedure for the determination of tensile properties during maintained extension according to the European standard EN ISO 8340. Facade wood has been selected as a substrate: specifically, heat-treated Finnish pine, has been used. A group of ten commercially available industrially produced sealants, including polyurethane, silicone and MS Polymer sealants, have been selected. The aim of the research was to discover any differences that might appear in their resistance against maintained extension as well as their durability when variable temperatures are applied. The test results were evaluated and stated in a table that defines main adhesive and cohesive failures at 23 C and -20 C. The research proved the possibility of sealing wood substrates but only if the correct sealant is chosen. Also significant differences between individual sealants in the results they provide in combination with wooden cladding material were observed. Of all the tested sealants only two products passed.
