    1. Stop any water coming from behind the face first.
    2. Remove loose mortar, flaking material and old sealer, and dry-brush any salt.
    3. Repoint open joints and seal wider cracks.
    4. RAINCARE WR: dilute 1:10 with clean water and apply generously by brush, roller or low-pressure spray, with the second coat while the first is still wet.
    5. RAINCARE SWR: apply undiluted on a completely dry surface, let it penetrate 5 to 10 minutes, then the second coat wet on wet.
    6. Keep rain off for 24 to 48 hours.

    A repellent keeps rain out of the face but does not stop ground moisture or a leak from behind.

    The silicone lines the pores so rain is shed while the wall stays breathable and can go on drying, without changing its look.
