Blueskin SA
Description Blueskin® SA
is a self-adhering membrane consisting of an SBS rubberized asphalt compound which is integrally laminated to a blue cross-laminated polyethylene film. Blueskin® SA is specifically designed to be self-adhered to a prepared substrate, providing an air/vapour/water barrier.Features:
- SBS modified membrane, flexible at low temperatures
- Impermeable to air, moisture vapour and water
- No flame required
- Thickness controlled at point of manufacture
- Excellent adhesion to prepared substrates of concrete, concrete block, primed steel, aluminum mill finish, anodized aluminum, galvanized metal, gypsum board and plywood
- Excellent compatibility with most Bakor adhesives and liquid air barrier membranes
- Self-sealing when penetrated with self-tapping screws
Uses
Blueskin® SA is designed for use as a self-adhered sheet air and vapour barrier. Its principal application is on walls of either masonry, concrete or gypsum board. It can also be used as a transition sheet in conjunction with Bakor Liquid Membranes where greater movement is anticipated, due to its high strength. Blueskin® SA is also used for tying into metal on curtain walls, windows and door frames.Preparation
Acceptable substrates are precast concrete, cast-in place concrete, concrete block, primed steel, aluminum mill finish, anodized aluminum, galvanized metal, gypsum board including DensGlass Gold®. All surfaces to receive Blueskin® SA must be clean of oil, dust and excess mortar. Strike masonry joints flush. Concrete surfaces must be smooth and without large voids, spalled areas or sharp protrusions. Concrete must be cured a minimum of 14 days and must be dry before Blueskin® SA is applied. Where curing compounds are used they must be clear resin based, without oil, wax or pigments. For best adhesion on Oriented Strand Board (OSB), install Blueskin® SA on smooth of OSB panel. All surfaces to receive Blueskin® SA must be primed with Blueskin® Primer, applied by lambs wool roller, brush or spray equipment at the rate of 1 litre per 2-6 m2 depending on porosity and texture of surface and allowed to dry for 30 minutes before Blueskin® SA is applied. Ensure that all primed surfaces receive Blueskin® SA in the same day. Alternatively, prime with Aquatac™. Allow to dry to a tacky film.Limitations
Not designed for permanent exposure. Good practice calls for covering as soon as possible. Not to be used in direct contact with flexible PVC/vinyl membranes or gaskets. Some sealants may discolor if in contact with the asphalt compound or may soften the asphalt compound. Contact sealant manufacturer for more information.Blueskin Primer
Description Blueskin® Primer is a rubber based adhesive primer for self-adhesive membranes.
Features
- Quick setting
- Aggressive tack provides adhesion of membrane
- Suitable for application at normal and low temperatures
- Easily applied
Uses
- Used as a primer for self-adhesive membranes such as Blueskin® SA, WP200 or RF200 when applied to masonry, concrete, wood, gypsum board, DensGlass Gold® and metal surfaces.
- Blueskin® Primer is the primer of choice on above grade applications of self-adhered membranes where a quick setting, aggressive tack, solvent based primer is required.
- Blueskin® Primer Ultra is ideal where a very fast drying primer is required.
- Convenient spray can application eliminates the need for brushes or rollers.
- Three minute tack time.
- Designed for applications above -12°C.
