Installation Guidelines
The full manual for Petrotac, the peel and stick repair and waterproofing membrane: primer, mastic, surface preparation, placement, carrying temporary traffic, and paving over it. Includes guide specifications for pavement and for bridge decks.
The appendices are the reason to keep this one. There are two guide specifications in the back, one for pavement and one for bridge decks, written to be dropped into a contract. If you are specifying a self-adhering strip membrane and starting from a blank page, start from there instead.
Primer is not optional and it is not the same thing as tack. Petrotac bonds to the primer, the primer bonds to the pavement, and skipping it because the surface “looks clean enough” is the standard way to get a membrane that lifts at the edges within a season. Appendix C names the primers and mastics that are recommended, which saves an argument with whatever is on the truck.
Temporary traffic gets its own section, and it is worth reading before you plan a phased job. There are limits on what the membrane will take before the overlay goes on.
Petrotac and MTK cover similar ground. If you are choosing between them for a particular repair, call us and we will tell you which one we would put down. Road Fabrics installs interlayers as well as supplying them.
