floorsaver Waterproof Roof Paint is a bitumen based coating reinforced with rubber and fibre. This makes it flexible, unlike ordinary bitumen coatings, meaning it won't sag in the summer sun, or split as the roof naturally flexes and moves. It can be used as an emergency leak stopper or to coat and extend the life of existing roofs.

      How to Use

      Step 1 - Preparation:

      • Preparation is quite minimal. Sweep off any moss, algae or dirt. If there has been a heavy fungal infestation use a fungicide and wash off.
      • You can use floorsaver Waterproof Roof Paint in the rain as an emergency repair. For long term repairs the surface should be as dry as possible. When coating large areas, we recommend that they are dry as trapped moisture can delay drying.


      Step 2 - Repairs:

      • Holes, cracks and splits can be filled using floorsaver Waterproof Roof Paint mixed with dry sand to form a stiff mortar. Prime the repair with a coat of the Waterproof Roof Paint, then trowel in the mortar.


      Step 3 - Application:

      • No need to stir.
      • Easiest using a brush, but a roller is possible on flat, felted surfaces or flat concrete.
      • Aim to use 1kg per 1m².
      • Clean equipment with White Spirit.
      • Drying time approximately 24 hours.


      Tip - If there are 'suspect' areas of the roof such as panel overlaps or felt joints but you are intending to coat the whole roof, we recommend just running a brush line of floorsaver Waterproof Roof Paint along the join, allowing it to dry and then coating the whole roof the following day.
