  • all-weather-box-of-12

    Bond-It Rain Mate All Weather Sealant – Box of 12


    Bond-It Rain Mate All Weather Sealant is a superior and highly flexible, water repellent, general purpose sealant that has excellent adhesion to all surfaces, even when damp.


    It suitable for use on brick, concrete, stone, all metals, painted or bare wood, glass, vinyl and most plastics. Also, it is compatible with bitumen and asphalt for roof repairs in damp conditions. Finally, it is ideal for sealing doors, windows, roofs, cladding and vehicle bodies.


    Primers are not usually required. For application in damper conditions, disburse any standing water and residual dirt from the substrate.  Dry the surface as well as possible with either a cloth or paper towel prior to applying sealant. All RAIN-MATE colours will adhere to bitumen and asphalt but we only recommend black for this purpose as unsightly discolouration can occur with white and clear.


    Not for use on polystyrene, polycarbonate, plastic roof lights or other surfaces sensitive to solvents. Do not apply at over 60o C or on surfaces which exceed 80o C in use.

    Health & Safety

    • High Adherence
    • Cure Time 20 to 30 mins.

    Cure Time

    The life of the tin is 20 to 30 minutes at 25C, this is affected, but the outside temperature and the sealant temperature. Final cure, when full working properties are developed, occurs within two days at 25C, although the sealant will normally bear traffic within 2 hours of application. Higher temperature will result in a faster cure time; low temperatures will result in longer cure time. Do not apply at temperatures below 4C.


    Ensure that the joint is clean, free from dust and dirt. The joint should also be dry; any contaminant should be removed, the previous sealant, if re-sealing is taking place, must all be removed. If you are backing the joint with backer foam strip, ensure the backer strip is bonded to the base of the joint and proceed to apply. Priming of the surface should be done once the joint is cleaned, the joint faces should be primed with the appropriate primer. CM Primer C is recommended.

    CM 200 PF Mixing and Application

    Open Pack B and empty the contents into Pack A – Stir for five minutes, preferably using a slow speed electric drill with a mixer paddle, the mix is one. Take care to avoid including excess air. Pour or gun apply immediately into the primed joint. Current practice requires that the sealant shall be poured to a level between 3mm (Summer) and 6mm (Winter) below the wearing concrete surface.
