Techno Contact Adhesive has many uses including adhering EPDM membranes to upstand, masonry and vertical surfaces and as a deck adhesive on old concrete and asphalt.
Techno contact adhesive is solvent based and used to adhere the EPDM membrane to upstands, masonry and vertical surfaces or old felt.When applying to either upstands or decks, make sure the adhesive is touch dry before securely applying the membrane. If the membrane is applied when the adhesive is still wet, you may find bubbles start to appear under the membrane itself.
Upstand ApplicationUse a paintbrush or 4-inch mini roller to apply contact adhesive to both surfaces. Ensure that the contact adhesive is touch dry before rolling the membrane onto the substrate/up-stand.
Deck ApplicationUsing a paintbrush or roller, apply contact adhesive to both the deck and underside of membrane evenly. Ensure that the contact adhesive is touch dry before rolling the membrane onto the deck.Note: it is not possible to reposition the membrane once stuck down using contact adhesive.
Membrane and substrate must be dry and dust free prior to application. Allow approximately 5-10 minutes for the contact adhesive to become touch dry dependant on weather conditions. If the membrane is bonded whilst the contact adhesive is still wet you may notice bubbles appearing under the membrane.
