Henry Air Bloc 06: 5gal Barrier Membrane

Henry Air Bloc 06: 5gal Barrier Membrane

Henry Air-Bloc 06 – Water Based is a single-component, cold applied, rubberized asphalt emulsion designed for use as an air and vapor barrier on a wide variety of porous substrates including concrete, CMU, and gypsum sheathing, including Dens-Glass Gold. It is ideally suited for use on substrates with numerous projections such as masonry brick ties. Blueskin SA membrane is used in conjunction with Air-Bloc 06 WB to span the interface of dissimilar materials as a transition sheet. This product may also be used for waterproofing foundation walls and other structures.

Uses

Designed for use above grade to provide an effective air, vapor and rain barrier on construction surfaces such as masonry, concrete or gypsum board. Below grade, this product can be used for waterproofing cast-in-place concrete and CMU foundation walls and footings.

Surface Preparation

All surfaces must be clean, free of grease, dirt, or other contaminants and must be reasonably smooth. Mortar joints on masonry substrates shall be struck flush. Form tie holes and voids in poured concrete shall be filled flush
and smooth, and allowed to cure for a minimum of 24 hours. Surfaces may be slightly damp but not wet or saturated.

Application

Henry Air-Bloc 06 WB is applied by brush or spray. Do not apply when air temperature is below 40°F, or if there is a threat of rain or temperature below 40°F within 48 hours or a chance of freezing within 48 hours. All surface
voids, holes and cracks must be completely coated to attain the dampproofing or waterproofing qualities. Dries to touch in approximately 4 hours (@ 50% R.H., 70°F), sets in approximately 24 hours. Drying will be slower, 2 to 7 days, in cool damp weather. Allow to dry between coats. On below-grade foundations, let cure at least 48 hours, with good air circulation, before exposure to water or backfilling. Protect surface with appropriate barrier board prior to backfilling.

Coverage

Vertical Surfaces:

Apply at a rate of 25 square feet per gallon for a wet film thickness of 64 mils (dry film thickness 45 mils) for concrete, plywood, OSB, gypsum sheathing, and Dens-Glass Gold®. Apply at rate of 20 square feet per gallon for wet film thickness of 80 mils (dry film thickness of 56 mils) on CMU or other very porous masonry surfaces.

Clean Up

Spray equipment can be flushed out with water. Use mineral spirits to remove dried films.
