Tremco Sealant Products
Does anyone know the difference between Tremco acoustical sealant and Tremco TREMPRO JS-773? I know the Tremco accoustical sealant is the black death that is known to have properties which make it good for air sealing. The Tremco TREMPRO JS-773 is quite a bit cheaper and is described to be non-skinning and non drying like the acoustical sealant, but I don’t really hear of anyone using it. The TREMPRO JS-773 also seems more readily available online. Would the TREMPRO JS-773 be suitable for sealing the sill plate if used in conjunction with an EPDM gasket?
