BARR Waterproofing Mastic for Roof Repair, Waterproofing, Plaza Deck Sealing & More.

BARR™ is a liquid cold applied single component waterproofing membrane that cures by exposure to the
atmospheric and or substrate moisture to form a continuous, tough, reinforced elastic waterproof seal. BARR is also available in calking tubes for flashing and patch work. BARR Flash & Patch is an elastomeric waterproofing material for use in repairing roof leaks, shingles, roof valleys, seams, chimneys, flashing's and emergency repairs. BARR Flash & Seal Tubes are perfect for use in green applications.

Unlike many waterproofing membranes BARR Bonds to asphalt and concrete. BARR is Solvent free, 100% solids and will not shrink. Another advantage to BARR is that it will skin over in about 10 minutes which greatly reduces dirt pick up. BARR has Superior adhesion to most construction materials

BARR can be used to waterproof planter boxes, sealing and repairing parapets, plaza decks
and many roofing systems, including “green”. BARR is also a versatile roof repair product which can even be used to line and waterproof gutters and a horizontal joint sealer.

BARR can be used below grade! BARR is perfect to use as a positive-side waterproofing for sealing foundations. A positive side waterproofing membrane is a membrane which is applied on the outside of the system. Coating the exterior foundation wall would be a good example of positive side waterproofing which BARR is perfect for. Coating the inside basement wall, to keep the water from getting in would be negative side waterproofing. BARR would not be suited for negative side waterproofing.

BARR is also used in between slab waterproofing, equipment wells and other underground construction. BARR is solvent free and compliant with all known environmental and OSHA requirements. It can be used in confined spaces without respiratory protection.

BARR forms an elastomeric rubber that is resistant to thermal shock. It will not crack in extreme cold or slump due to softening at high temperatures like conventional asphalt or coal tar based coating.

Coverage: BARR will cover about 55 Sq. Ft. Per gallon/ per coat. Two coats is recommended.

BARR is generally trowel applied in a two coat minimum application rate of 30 mils per coat.  Due to the fast tack-free time, the second coat of BARR can usually be applied within thirty minutes of the first coat.
Math Extension for Application Rate
10’X10’ area = 120”X 120”= 14,440 sq. inches
14,400 sq. inches X 0.60 mils (total)= 864 cubic inches
864 cubic inches divided by 231 cubic inches per gallon = 3.74 gallons per square (3.75 gallons)

This application rate is calculated for a smooth substrate.  Rough substrates will require additional material.
