Product Description

ZOLVTEK PRIMER is a solvent based, full bodied black Bitumen paint. It is used as a surface dressing to  asonry, concrete and metallic surfaces or to improve the bond of bituminous materials to the substrate. When dry, the product forms an odourless and taint free Bitumen film suitable for the protection of  metals, concrete roofing, felt, fibre cement, corrugated iron, Bitumen and wood against water attack. A single component elastomeric waterproofing membrane with high elasticity and low water r permeability. It is particularly suitable for a wide range of applications including wet areas, swimming pools, foundations, basements, terraces, retaining walls, bridge abutments, planters, inverted roofs and remedial repairs to felt, Bitumen, concrete, fibrous cement or other roof structures when protected from exposure to direct sunlight. ZOLVTEK PRIMER is a tough waterproofing system based on modified Bitumen, co-polymers and a carrier solvent. It is highly resistant to aggressive soils and soluble salts providing an effective continuous barrier and protection against water borne damage. ZOLVTEK PRIMER is ideally suited as a vapor/salt barrier to building facades behind granite, marble, stone cladding and curtain wall elements.
 
Solvent-Based Bitumen Primer
Prime D**1
 
FEATURES AND BENEFITS
 
Bitumen Primer D**1 is ready for use and should not be thinned. Apply by brush or spray. A minimum of two coats of Bitumen Paint should be applied, the first been allowed to dry (normally **4 hours depending on weather conditions) before the second is applied.
 
DRINKING WATER TANKS
 
Surfaces should be dry and free of mill scale, rust and dirt. All surfaces should be degreased immediately prior to coating. Brush application is preferred to ensure that all recesses, edges, rivet, and bolt heads and nuts are coated thoroughly. Drying may be assisted by the provision of a forced air draught. A three coat system is suggested for the internal treatment of drinking water tanks. Apply 3 coats, normally allowing a *4 hours drying period between coats. It is important that the first coat is thoroughly dry before application of the second coat. Use clean, uncontaminated application equipment. After the third coat has dried thoroughly allow at least seven days for the coating to set. Before the tank is put into service it should be filled with cold drinking water and drained after not less than 4 hours. If a taste is detected in this water, the flushing should be repeated. The paint is not suitable for hot water
tanks.
 
• Do not use in areas where subsequent solvent contact is likely.
• Avoid inhalation of vapors in confined spaces.
• Bitumen Paint may bleed through any paints subsequently applied over it. Apply a PRIMER recommended by the paint manufacturer before over painting.
• Allow sufficient drying time between coats.
 
PROTECTIVE COATING ON CONCRETE
Since concrete and some stone surfaces may be porous, an initial PRIMER coat of D**1 Bitumen PRIMERR should be applied.
 
• Excellent adhesion and self healing properties.
• Excellent penetration.
• Compatible with all bituminous products.
• Anti corrosive coating.
 
 
SURFACE PREPARATION
• As with all surface coatings preparation of the surface is of great importance and will influence the degree of adhesion obtained and the life of the coating. All surfaces must be sound stable and thoroughly clean and dry. Metal surfaces should be wire brushed to remove rust. Where long term protection is required an initial treatment of a rust inhibitive product such as red lead or zinc phosphate should be used. Loose or blistered paint should be removed as should tar based paint systems. New galvanized surfaces should be roughened with a wire brush or treated with a proprietary etch prime Porous surfaces should be primed with D**1
 
Bitumen PRIMER.
• All substrates must be sound, clean, dry, smooth and free from protrusions, voids, honey-combs and high spots. Presence of curing agents, paint and oil will impair
adhesion.
• Moss and lichen must be removed and area treated with proprietary fungicidal wash to kill spores and inhibit further growth. Wash the area thoroughly with clean water and allow drying. Fillets must be provided at corners or sharp angles using 4:1 sand and cement mortar, modified with a good quality bonding agent.
• Priming is normally not required on good quality, well prepared substrates.
• Cracks: All shrinkage and non-structural cracks must be treated with not less than 1.5 mm coating of ZOLVTEK PRIMER extending *5mm either side of the crack. Allow to cure overnight prior to general application.
 
• ZOLVTEK PRIMER should be applied by brush to obtain a continuous unbroken film.
• Two coats are required with the second coat applied at the right angles after the first coat has cured.
 
• ZOLVTEK PRIMER must be protected from mechanical damage during subsequent construction of backfilling works.
 
• Any damage may be repaired by a spot application.
• If a water flood test is run, the membrane should cure for a minimum of days.
• Whilst ZOLVTEK PRIMER is resistant to frost, adhesion will be impaired if applied to frosted substrates. Application should be avoided if substrate temperatures are below 5°C or rain in imminent.
