Frequently Asked Questions
What type of surfaces can your products be installed on?
The ideal subsurface for our products is AC sanded plywood, however some lower grade woods and concrete can be accommodated depending on circumstances and intended usage. Please submit an inquiry via our contact page if you have any questions regarding adhesion to your surface.
What type of preparation/finishing needs to be done in advance of an installation?
For roofs or decks, a minimum of ¼” per linear foot of pitch to be built into the surface to allow for proper water runoff.
When building 16” on center, a minimum of ¾” exterior plywood must be installed as sub-flooring.
At walls/tie in points, any stucco, vinyl or other siding must be removed at least 12” from surface to be coated in our waterproofing membranes. This allows for maximum waterproofing and proper water runoff. Siding or counter-flashing may then be installed over waterproofing membranes after project completion.
Through-posts for rails are to be installed prior to arrival so that there is no need to drill holes or cut into the membrane to insert a rail system. Please submit an inquiry via our contact page prior to your job regarding what type of railings you intend to install.
Doors leading to the surface must be removed prior to arrival in order that door thresholds may be sealed with a continuous sheet of waterproofing.
Railings must not be fastened until color coat layer is complete (polyurea coatings only).
During and after the job, do not penetrate the waterproofing membrane as this will compromise the integrity of the surface. This includes any threshold and wall space within 4” of the horizontal deck surface. If you have any questions or concerns regarding surface penetrations, please submit an inquiry via our contact page.
