Primero Pro Deck Waterproofing Membrane

PRE-STRIPPING:

Pre-striping of cracks and joints: clean surface and remove old waterproofing that has been separated or unbundled. Cracks and expansion joints and areas where floor and wall meet should be filled by pre striping. Apply Primero Pro-Deck by brush by filling areas with joints and cracks 3” to 4" wide. Allow to dry and follow application instructions.

APPLICATION:

Apply 1 coat of Primero Pro-Deck horizontally. If paint is too thick; you may add up to 25% water to make paint into primer. Let it dry for 2 to 3 hours before recoating. 

Apply 1 coat vertically. Let it dry then apply second coat horizontally. For areas with substantial movement such as roof decks with (AHU) or other machinery, apply with waterproofing fiber cloth. 

Apply 1 coat of Primero Pro Deck vertically. While still wet, lay fiber cloth into the paint. Use the brush to push fiber cloth firmly onto the paint, squeezing out air bubbles to eliminate creases. Let it dry for 2 to 3 hours then reapply second coat horizontally. You may apply a third coat vertically for better coverage and protection. It is recommended to apply 1 to 2 square meters at a time so that paint will not dry while applying fiber cloth. This will increase tensile strength. 

Allow 12 to 24 hours for foot traffic and 3 days for full cure. For old walls, remove any loose or flaking paint. Sand surface to rid of efflorescence and apply wall putty or new cement plaster for areas with deep cracks. Let it dry and apply Primero Pro-Deck with the same instructions above.
