- Sandwiching between existing and new concrete substrates
- Liquid vapour barrier between toppings and slabs
- General tiled areas to prevent moisture ingress
Surface suitability
- Concrete (cured at least 28 days, primed with Gripset GP Primer)
- Render (cured at least 7 days, primed with Gripset GP Primer)
- Masonry (pointed flush, defects filled and levelled, primed)
- Compressed fibre cement sheet (primed)

- Plywood (external grade, primed)
- Aerated concrete (highly porous, 2 primer coats recommended)
Gripset 38FC is not to be used as a trafficable surface and not to be used as a finished membrane exposed to UV. It must be covered over with toppings, tile beds or overlay finishes. Do not apply when rain is imminent, or when surface or ambient temperatures are below 5C or above 30C. Not to be used in areas subject to rising damp or negative hydrostatic pressure; damp substrates and substrates with high residual moisture must be primed with Gripset E60 or Xpress H20 Primer Plus, not the GP Primer supplied in this kit. All finish coatings over the membrane must be water based and solvent free. The BRW PF Tape must not be left as an exposed flashing or exposed joint seal, must not be used over expansion joints, must not be used in negative hydrostatic applications, and is not compatible with solvent based materials applied directly over it. Elastoproof Collars are not compatible with solvent based materials, adhesives or sealants and must be bedded into a wet film of membrane before it skins. Gripset 38FC contains isothiazolinones and may cause an allergic skin reaction.
