Product Details, Safety, and Installation
  • Can TREMproof 260 be applied in cold weather below 40°F (5°C)?

    TREMproof 260 may be applied at temperatures below 40°F (5°), however, all substrates must be clean, dry and frost-free.  It is Tremco’s best recommendation to apply products when substrate and ambient temperatures are at 40°F (5°) and rising. Please note the following when applying these products at temperatures below 40°F (5°).

    Special Note: TREMproof 260 must be kept from freezing while in the pail and spray lines. It is also recommended to co-spray to speed the curing process and reduce the potential for washout in the face of inclement weather.

  • Does TREMproof 260 require a protection course?

    TREMproof 260 requires a protection course.  A TREMDrain drainage course may be an acceptable substitute or used as an add-on.  TREMDrain DPI (drainage, protection and insulation board) is designed for use with TREMproof 260 and may be applied while the membrane is still tacky.  The semi-rigid nature of the board acts as a protection course for the TREMproof 260 waterproofing membrane.

  • Can TREMproof 260 be applied on a horizontal deck between slabs?

    For between slab applications, only TREMproof 250GCTREMproof 201/60TREMproof 6100 Hot Rubberized Asphalt or Paraseal should be used.

  • How long does the concrete have to be cured before TREMproof 260 can be applied?

    TREMproof 260 only requires 24 hours following the removal of concrete form work.

  • What is the typical minimum dry mil thickness requirement for TREMproof 260?

    60 mils.

  • Can TREMproof 260 be spray-applied for below-grade waterproofing?

    TREMproof 260 may be suitable for spraying vertical foundation walls only.

  • What is used to co-spray TREMproof 260 and at what percent?

    Tremco recommends using calcium chloride to break the TREMproof 260 emulsion at a mix ratio of 2% by weight with water. The recommended calcium chloride flake should be a 77% test CaCL2.
