Roberts understands installing a new outdoor floor covering can be challenging. Here are some key product usage points regarding the 6700 adhesive that may improve performance and satisfaction. The cure of the 6700 could be affected if the adhesive is being used over treated plywood. Treated plywood is often "wet" with the chemicals. These chemicals can also adversely affect the composition and performance of the adhesive. Roberts does Not recommend the use of this adhesive over treated wood, Painted surfaces, EDPM or any such membranes. Cure can also be effected if Open Time was not observed prior to the installation of the carpet.
