Product Data Sheet
Primeseal
Two-pack, Water-Based Primer and Sealer |
Description
Duram Primeseal is a versatile two-part, water based coating suitable for most types of porous and semi-porous surfaces.
Primeseal has been designed for the dual roles of both a primer and a sealer.
As a primer, Primeseal is an excellent universal primer for all Duram
waterproofing membranes, anti-slip coatings, paints and coatings. It has
excellent bonding properties to most substrates and assists in the
prevention of water vapour transmission from the substrate thereby
minimising the risk of bubbles forming underneath membranes.
As a sealer, Primeseal exhibits excellent primary waterproofing and
sealing properties and enhances the waterproofing performance of
subsequent membranes and coatings.
Primeseal's standard colour is off-white but is also available in black
(minimum quantities apply) and generally used as a top coat over
Crystoflex to provide an attractive colour in water features.
Primeseal has very low VOCs and meets the 'Green Star' envirnmental criteria.
Uses
Duram PRIMESEAL is formulated:
• as a general and universal primer for most types of substrates.
• as a vapour transmission barrier (when applied at appropriate coverage rates).
• as a sealer coat over bitumen surfaces to allow the application of
solvent and water based waterproofing membranes and other coatings.
• as a sealer over damp surfaces to allow the application of urethane based waterproofing membranes.
• as an intercoat bridging coating to allow the application of incompatible coatings.
• priming and sealing of concrete, cement, cement render, timber, brick,
block work, FC sheeting, CFC sheeting, plasterboard and bituminous
surfaces.
• as a sealer against bitumen and tar based products staining grout and tiles.
• to provide good hydrostatic resistance to both positive and negative waterproofing.
• as a primer over bituminous and torch-on membranes so that they can be top-coated or re-membraned.
Suitable Surfaces
Duram Primeseal is suitable for most surfaces including:
• Concrete. cement, cement render, brick, block work, masonry, timber,
FC sheeting, CFC sheeting, plasterboard and painted or coated
surfaces.
• Abraded or etched ceramic tiles - but confirmation of specific projects should be sought from the Company.
• Primeseal may be applied to superficially damp surfaces although
not recommended and freedom from surface and running water and
continual dampness is essential. The surface must dry to allow the
product to dry.
Specification
The
information contained in this product data sheet is typical but does
not constitute a full specification as conditions and specific
requirements may vary from project to project. The instructions should
be considered as a minimum requirement but the applicator or contractor
must use their skill, knowledge and experience to carry out additional
works as may be necessary to meet the requirements of the project.
Specification for specific projects should be sought from the Company in
writing.
Limitations
Primeseal being an epoxy has low flexibility and is NOT designed to bridge cracks or expansion joints.
Primeseal can be effective for sealing the inside wall surfaces but without guarantee.
Benefits and Advantages
- Primeseal is user and environmentally friendly, solvent free and low in odour.
- Low VOCs and meets the 'Green Star' environmental criteria.
- Easy to apply by brush, roller, squeegee and spray.
- Quick drying.
- Has excellent adhesion.
- Excellent water barrier.
- Can be used as a primary waterproof barrier on rigid surfaces.
- It will not re - emulsify.
- Seals over most existing coatings.
- Excellent hydrostatic pressure resistant.
- Can be used to seal the negative and the positive sides of the substrate.
- Can be applied to superficially damp surfaces, which must become dry.
- Compatible with all Duram waterproofing membranes and floor coatings.
- Acts as a bleed sealer over bituminous surfaces.
- Excellent primer over torch-on waterproofing products.
Precautions in Use
Primeseal
is water based and contains no VOC's and is considered safe to use,
however, observe good hygiene and safety practices.The wearing of gloves
is recommended and goggles against splashes. Good ventilation is
recommended and avoid contact with skin, eyes and mouth. If poisoning
occurs contact Poison Information Centre. If swallowed DO NOT induce
vomiting, give plenty of water to drink and seek medical advice. If in
eyes thoroughly flush with clean water, holding lid open to ensure any
product maybe flushed away. If on skin wash with soap and water.
Priming and Surface Preparation
Good
preparation is essential. Surfaces must be sound, stable, dry, clean
and free of dust, loose, flaking, friable material and substances that
may diminish adhesion.
General Usage:
Mix equal portions of Part A and Part B (standard mix) thoroughly
to a homogenous consistency before application. Only mix enough product
that can easily be applied within 2 hours.
Bagging Primer Mix:
Thoroughly mix equal portion of Part A and part B of Primeseal,
then add 30% water and thoroughly mix and then add sufficient 3:1
sand: cement mix to the Primeseal liquid to form a brushable or rollable
consistency and apply to surface.
Concrete Blow-Hole Filler:
As above, but adding more sand:cement to the mix to increase its
viscosity. Coat the blow-hole with the standard mix Primeseal solution
and then fill hole with described viscous mixture.
Allow Primeseal to dry fully before over coating.
Application
Apply
by brush, roller, squeegee or spray, generally in a single coat using
sufficient product to provide a uniform, solid, off-white coat.
When priming timber, particularly particle board at least 2 coats should be applied.
When sealing bituminous surfaces, at least 2 good coats should be applied.
When using Primeseal as the primary sealer at least 3 coats should be applied.
For priming of superficially damp surfaces (freedom from continual dampness is essential) apply 2 coats.
Subsequent coats should be applied as soon after the preceding coat is fully dry and best within 48 hours.
The final coat must be uniform completely covering the surface.
Allow Primeseal to cure for 3 to 4 days prior to filling with water when used as a primary sealer.
Coverage
The
stated average coverage rate may vary depending upon type, condition,
porosity, texture of the surface and application technique.
Generally,
Primeseal should be applied at 4m² per litre per coat. Highly porous or
friable surfaces may require the application of an additional coat.
Colours
Standard colour is off white and is available in 1, 4,10 and 20 litre kits.
Primeseal is also available in black and other colours, by special order and minimum quantities may apply.
Drying and Curing
Drying
and curing of the product is affected by type, dryness and porosity of
the surface, temperature, humidity, ventilation, climate conditions and
application technique and therefore drying and curing can only be given
as a guide.
Touch
dry curing time is approximately 4 to 8 hours at 25ºC and
50% RH. Damp surfaces will increase curing time and will generally be
slower than had the surface been allowed to dry before applying the
Duram Primeseal.
Cold air and ground temperatures will increase drying times required.
Storage
Store in a cool, dry area away from direct sun light. Ensure unused product is sealed properly. Keep out of reach of children.
Clean Up
Wet spills can be cleaned up with water.
Tiling, Topping or Top Coating
Primeseal can be directly tiled, topped or over-coated.
