Fields of Application
- SolarTAC is ideal for roofs and walls in both commercial and
residential buildings.
- SolarTAC can be applied to substrates such as concrete, render, aluminium, steel, plaster, sheet, masonry, brick, wood, etc.
Features
- Easy to apply, non toxic and environmentally friendly
- Reduces radiant heat in dwelling
- Reduces energy consumption by cooling the building
- Has anti-mould and anti-fungal properties
- Electrometric qualities
Surface preparation All surfaces must be free from grease, oil and dust. Very smooth
surfaces should be roughened for better adhesion.
- Loose rust, moss, lichens, crumbling cement, deteriorated
fibre cement and degraded bituminous substances must be
removed either mechanically or chemically.
- Surface faults such as blisters, holes and cracks should be
cleaned out, then repaired with a flexible filler. Small hairline
cracks can be painted with SolarTAC - brush in, allow to dry,
then repeat until filled or at least sealed.
- Adhesion to porous substrates can be improved by priming
with Davco Primer. This is recommended because these
surfaces can be very weak and consequently when a coating
of SolarTAC is pulled up it actually tears away the surface to
which it is bonded. Sealing with Davco Primer greatly reduces
this type of potential failure.
- Rusty metal should be cleaned by blasting or other means to
a suitable standard then primed with a Rust Converter. Other
metals should be suitably primed or treated, e.g. for new
galvanising, degreasing, etch or roughen surface
before coating.
Application
- SolarTAC may be applied directly to all common building
substrates, i.e. concrete, render, aluminium, steel, plaster, sheet, masonry, brick. Some priming may be required depending on the substrate condition. (Please refer to our expertise.)
- Apply two or more coats to obtain recommended total
thickness by brush, roller, spread bar or air less spray gun. Ideal application temperature is between 10 - 30°C and relative
humidity 30 - 80% in rapid drying conditions. Mask large areas
into smaller zones to help obtain an even application
and appearance.
- Rinse brushes, etc. frequently in water to prevent drying/
clogging keep containers closed to minimise skin formation.
- In fast-drying weather conditions, adhesion to unsealed
absorbent or porous surfaces is significantly improved by
Davco Primer.
