PenSeal is a solventborne,water repellent, penetrating sealer designed to protect and treat masonry and cementitious structures for the prevention of water absorption. PenSeal impregnates the concrete to protect ingress of salts and chlorides. It protescts reinforced concrete from waterborne chloride ions making it an ideal protective surface treatment. PenSeal is designed to impregnate the concrete surface and permanently bond to the molecular structure of the concrete, thus changing its absorption characteristics.

Feature and benefits.

  • Clear, non-staining liquid.
  • Reduces salt and water intrusion by up to 90%.
  • Penetrates into pourous surfaces.
  • Prevents corrosion of reinforcement bars.
  • Prevents dampness inside buildings thereby reducing rising damp.
  • Repels water.
  • Able to miniminise efflorescence, alkali, silica reactions and freeze thaw problems.
  • Breathable, will not trap moisture, allowing water vapour to escape the structure.
  • Suitable for indoor and outdoor applications (UV stable).

Recommended substrates.

  1. In-situ concrete and masonry.
  2. Stone.
  3. Terrazzo.
