Q19 Waterproof Paint

For Decorating Damp Walls and Problem Areas

Product Function

New Q19 is a two pack epoxy resin paint which has been dispersed in water. The 'new' formulation is even easier and more economic to use. When fully cured, it provides a tough, colourful, tile like and impervious eggshell finish.
Remember - Q19 Clear penetrates so well that when cured, it becomes an integral part of the structure.

Main uses

• As a decorative waterproofer on damp surfaces, inside and out.
• As an easy-to-clean anti graffiti finish.
• As a 'Tanking' paint in basements and cellars.
• Waterproofs any porous substrate including concrete, brick, blocks, stone, plaster, hardboard, MDF, chipboard, cardboard etc.
• As a tough, mould resistant, hygienic wall finish for factories, farms, breweries, canteens, swimming pools etc. Easy to steam clean or pressure hose.
• As an integral waterproofing membrane under renovating cementitious plaster systems such as Tilcon Limelite.
• As an alkali resisting primer and damp-proofer beneath masonry paints etc.
• As a tough, hygienic, colourful finish in wet areas, changing rooms etc.
• For priming and sealing solvent sensitive surfaces, i.e. asphalt, polystyrene, bitumen etc.
• To protect and re-decorate walls and cellars after flooding. It speeds up renovation work helping to prevent further ingress of moisture.

The Three main Q19 Systems

1. One Coat - Alkali barrier and Stabiliser. A single coat of clear used on concrete, plaster, cement, asbestos / cement, brick or stonework will provide an alkali barrier, prevent bleeding or staining and generally stabilize the surface prior to painting with conventional paints.
2. Two Coat - Damp - Proof Membrane. Two coats of Q19 will produce a protective membrane. If Q19 is NOT required for its decorative finish, then a 2 coat system is usually adequate as a damp-proof membrane on a smooth surface or as a sealer on a solvent sensitive surface i.e. one coat Q19 Clear, plus one coat Q19 Colour applied 90° to each other. After 7 - 10 days, wallpaper, tiles and other decorative paints may be applied.
3. Three Coat - For Full Protection and Decoration. Maximum properties are obtained with a three coat system. Ie. one coat of Q19 Clear followed by one coat of Q19 Colour, with a final coat of Q19 Colour. This ensures that on most surfaces, the Q19 paint film is complete, unbroken and of tile-like appearance and durability. On sound, dry, well sealed surfaces, the initial coat of Clear may not be needed.

Preparation

Q19 Should only be applied to sound, clean, grease-free surfaces. Holes and cracks should be repaired before painting. Existing paintwork should be very sound and any gloss removed to provide a key. Q19 must not be applied where there is a risk of running water, condensation or temperatures below 5°C. Use electric warm air blowers if necessary and ensure good ventilation.

Mixing

Q19 is a two-component product. Base and hardener are supplied in matched quantities and must be thoroughly mixed together before use. Mixed material has a pot life and must be used immediately.

Application

Brush, short pile lambswool roller or spray. For spray application, Mix base and hardener very thoroughly adding 5-10% cold water to reduce viscosity before loading paint. Airspray at 60psi with a 206 tip. Airless spray at 1800psi with Varitip 20-25 thou. Wash equipment with cold water every hour to prevent build up of materials. Allow six to twelve hours between coats. Note Health and Safety advice when spraying.

Drying

Q19 Eggshell will be touch dry in about 5 hours at 15°C and will be fully cured in 7 - 10 days. These drying times will vary according to temperature air flow.
