Adhering Membrane With Water Based Bonding Adhesive

RUBBERALL® EPDM Water Based Bonding Adhesive is to be used only for bonding RUBBERALL® Membrane and Flashing to underlying roof surfaces, i.e. decking or insulation, walls, penetrations, etc. RUBBERALL® Water Based Bonding Adhesive is not to be used for field seaming of RUBBERALL® Membrane or Flashing. The application of this adhesive should be as follows:

  • Apply adhesive at temperatures of 40 degrees F (4 degrees C) and rising with no chance of freezing in the next 48 hr.
  • Water Based Bonding Adhesive comes in 3-1/2 gallon containers

Application to Non-Porous Surfaces Horizontal Surfaces (isocyanurate insulation) and Vertical Walls

Figure 10

Fold the membrane back so that half of the sheet is exposed. Apply 5-6 mils of adhesive to both surfaces and allow it to turn transparent and it is dry to a finger touch. The membrane can then be folded over the insulation or up the wall. Broom or squeegee the membrane surface to insure intimate contact of the membrane to the substrate. Coverage rate is approximately 100-120 sq. ft. / gallon but may very depending job site conditions. Remove Water Based Bonding Adhesive from seam area with damp cloth.

Application to One Porous Horizontal Surface (wood fiber board, gypsum board, plywood ,OSB)

Fold the membrane back so that half of the sheet is exposed. Apply 10-12 mils of adhesive to the porous substrate only with a roller. Immediately lay the membrane into the adhesive while wet. If the adhesive has turned transparent, a thin coat of adhesive must be applied to the membrane. Laminating onto one surface while the adhesive is wet will allow for some repositioning of the membrane prior to the adhesive taking a set. Immediately broom or squeegee the membrane after it is laid into the adhesive to insure intimate contact. Coverage rate is approximately 120 sq. ft/gallon but may vary depending on job conditions.Remove Water Based Bonding Adhesive from seam area with damp cloth.
