Usage Guidelines Surface preparation
Concrete surfaces shall be cured for a minimum of 28 days.
Surface should have light steel trowel finish followed by a fine hair broom or equivalent finish.
Substrate should be free from dust, oil, curing agent resi- dues and other contaminants.
All shrinkage and non moving structural cracks under 1.5mm shall be filled with not less than 1.5mm (1500 wet microns) of TREMproof 60R extending 75mm to both sides of the crack.
Cracks wider that 1.5mm should be routed to 6mm width and 13mm depth. Install a closed cell polyethylene backing rod and seal with TREMproof 60R extended to 75mm either side of the joint.
Wherever a vertical penetration exists (eg parapet walls, columns, stacks etc.) install a 25mm fillet of TREMproof 60R at the point where the vertical and horizontal surfaces intersect. The TREMproof 60 membrane should then be applied over the fillet to a height of approximately 75mm to form an overflashing.
Voids and honeycomb must be patched with a non-shrinking, quick setting grout. Allow the patched area a minimum of 7 days to cure.
To reduce blisters caused by air entrapment on rough and porous concrete, use TREMproof 60H thinned 20% with Xylol as a primer.
PVC plumbing shall be primed with TREMCO Primer No. 6 and shall receive a preparatory coating of TREMproof 60.
All metal surfaces to receive TREMproof 60 shall be primed with TREMCO Primer No. 6.
TREMproof 60 preparatory work shall be cleaned with Xylol. To join fresh applications of TREMproof 60 to those that are more than 48 hours old, apply TREMCO Primer No. 17 at the interface. Recommended overlap is 150mm.
Method of application
Install TREMproof 60R by trowel and TREMproof 60H by squeegee, directly to the clean substrate.
Apply at a minimum thickness of 1.5mm (1500wetmicrons) This 1.5mm is in addition to the preparatory work.
A slip sheet of heavy duty builders plastic must be installed between the membrane and any solid topping.
Store in original unopened packaging in dry conditions between +5oC
