ROOFGARD

USES
BITUMAT ROOFGARD is designed to waterproof and protect built-up roofs, metal roofs, modified bitumen roofs, exterior foundation walls, concrete decks and walls, valley gutters, etc.
BITUMAT ROOFGARD can be used to restore and waterproof either existing roofs or new cold applied roofs. Roofgard can withstand only normal structural or thermal expansion and contraction.

OUTSTANDING FEATURES

  • BITUMAT ROOFGARD has the ability to resist oxidation, high heat and ultraviolet light.
  • The special chemical additives allow the product to penetrate existing surfaces and form a durable bond resistant to peeling and separation.
  • Flexible and pliable. Can withstand normal roof stresses, expansion and contraction.
  • Prolongs the life of both old and new roofs.
  • Waterproofs existing roofs economically.
  • Single component and cold applied, minimizing labour costs.

APPLICATION
The surface must be thoroughly cleaned and should be free from dirt, debris, loose gravel, scale, etc. It should also be dry. If the surface is brittle asphalt  , prime with BITUMAT BITUPRIME and allow to cure to tack free. Repair all blisters, cracks, splits, torn-up flashing or any other defects prior to coating. Apply with roofing brush, squeegee, or airless spray equipment at the recommended coverage rates.
Used for application in conjunction with membrane as Built-up-roofing or capsheet. 

DESCRIPTION
BITUMAT ROOFGARD is a high quality, cold applied, fibrated waterproofing coating formulated with select ductile bitumen, blended with pure petroleum solvents and compounded with reinforcing fibers, gelling agents, mineral stabilizers and a special adhesion additive.

CLEANING
Tools : Clean with kerosene
Hands : Use a hand cleaner or kerosene followed by soap and water.
