Primeseal MC – Part A & B (Two-part)

• Primeseal MC is suitable for potable (drinking water) applications and can withstand up to 25 meter head of water pressure.
• Waterproofs and seals damp and green (newly laid) hardened concrete.
• Waterproofs negative (inside) and positive (outside) surfaces.
• Waterproofs basements, retaining walls, lift wells, cellars etc.
• Waterproofs tanks and water retaining structures.
• Excellent primer for subsequent Duram membranes, paints and industrial coatings.
• A primer and sealer of concrete, cement, cement render, timber, brick, block work, FC sheeting, CFC sheeting and plasterboard.
• A primer over bituminous and torch-on membranes so that they can be top-coated or re-membraned.
• An intercoat bridging coating to allow the application of incompatible coatings.

• Can be applied to green (newly laid) hardened concrete.
• Is a barrier against low water vapour pressure.
• Suitable for contact with potable (drinking) water. Conforms to AS4020-2000.
• Withstands up to 25 meter head of water.
• Applied in sensitive areas.
• Quick drying.
• Has excellent adhesion.
• Used as a primary waterproof barrier on rigid surfaces.
• It will not re – emulsify.
• Seals over most existing coatings.
• Used to seal both the negative and the positive sides of the substrate.
• Compatible with all Duram waterproofing membranes and floor coatings.
• Acts as a bleed sealer over bituminous surfaces, including over traditional torch-on waterproofing products.

The stated average coverage rate may vary depending upon type,
condition, porosity, texture of the surface and application technique.
As an effective waterproofing membrane or barrier against low
water vapour pressure: A minimum of 2 coats applied at 3m² per
litre per coat. The dry film thickness should be 0.33mm. If this
coverage is not achieved in two coats, an additional coat should be
applied. The waterproofing properties are enhanced when used in
conjunction with suitable Duram waterproofing membranes.
As a general primer: 1 coat applied at 3m² to 4m² per litre per coat.
As a bitumen sealer to enable subsequent membranes or coating
to be applied: 2 coats applied at 5m² per litre per coat.
As a sealer of a damp surface to allow the application of a
polyurethane membrane: 2 coats applied at 4m² per litre per coat.
