How do I apply heat-resistant solar lacquer?
You've heard of heat protection films, shutters and air conditioning. Discover solar lacquer!
The solar lacquer is a great all-round alternative for creating an effective sun protection film!
It can be used on all types of synthetic glazing (polycarbonate, plexiglass, lexan, exterior glazing for roofs, glass roofs and verandas, domes or skydomes, skylights, etc.).
Solar lacquer is highly effective in reducing the heat in your home. Its white tint also protects against glare.
Based on alkyd resin and solvent, it ensures excellent adhesion for a long-lasting finish.
How do I apply heat-resistant lacquer?
Prepare your equipment
Essential tools are your best allies for quick and easy application of solar lacquer:
- Brite scotch tape
- St Marc oxydrine
- Short-haired roller (recommended for small surfaces)
- Paint sprayer (recommended for large surfaces)
You can find all these items in DIY stores near you.
Once we've got everything we need, we can get started on our glazing heat protection workshop!
Preparing to apply solar heat protection lacquer
Like all actions when applying a product to glazing, it's important to thoroughly clean and degrease the surfaces to be treated to eliminate oily, greasy traces and imperfections.
Prefer St-Marc "Oxydrine" or another washing powder.
Rinse with clean water and leave to dry.
When cleaning, use industrial-grade Scotch Brite and scratch the plastic substrate to improve adhesion of the solar lacquer:
- For domes: stripe in the round. Apply from bottom to top. Repeat on all 4 sides of the dome.
- For corrugated and "cintronefs": line from top to bottom. Apply from bottom to top, and sweep a final veil over the corrugated areas (from top to bottom).
Application of your sun protection lacquer by roller
To apply solar lacquer, use a short-nap roller: apply two thin, criss-cross coats, one hour apart.
Spray application: To protect large glass surfaces from the sun
This application is recommended for large surfaces, using an electric or compressor gun.
Spray from approx. 30 cm from the substrate, spray cone approx. 30 cm in diameter.
Stir the solar lacquer inside the can before pouring it into the gun's reservoir.
Application is made in several crossed veils (3 as a general rule).
The first veil should be particularly light so that the lacquer clings perfectly to the substrate and dries very quickly.
We recommend an application pressure of 2.8 to 3 bar.
The nozzle should be approximately 0.8 mm (depending on the type of gun used and the operating pressure) and the spray vertical.
Drying and finishing the sun protection lacquer
Solar lacquer dries relatively quickly, between 15 minutes and 2 hours, depending on the outside temperature.
It is dust-free after 15 minutes and cured after 2 to 6 hours.
Now you know how to apply a solar lacquer to protect your synthetic glazing from the heat:)
