ThermoDry Roof

The SurfaPaint ThermoDry® Elastomeric Roof Paint is a high quality elastomeric acrylic paint with thermal insulating properties. It is ideal for exterior use in horizontal and inclining surfaces. The Elastomeric Roof Paint forms an impermeable and elastic film with excellent adhesion that retains its elasticity even under very low temperatures. It is resistant to adverse weather conditions and has long lasting durability. Its fluoropolymeric composition makes it dirt repelling and easy to clean.

Thermal Insulating Properties

Poorly insulated roofs are the major source of heat transfer in building structures. As a result, large amounts of energy are required for cooling in the summer or heating in the winter. The Elastomeric Roof Paint contains special nano and micro-sized thermal insulating particles that block heat transfer, reflect thermal radiation, and create a moisture barrier that can help significantly with energy saving.

Water-Tight Film

The Elastomeric Roof Paint has excellent durability to UV radiation and alkali. It also forms an impermeable and elastic film of excellent adhesion, which retains its elasticity even under very low temperatures. It is resistant to adverse weather conditions and has long lasting durability. If that’s not all, its fluoropolymeric composition makes it dirt-repelling and also easy to clean.

Liquid water permeability “non-permeable” by water according to EN ISO 1062-3:2008
Fungal resistance excellent resistant against fungi & algae, Class 1 according to BS3900-G6:1989
Elasticity -10°C: 315%, 23°C: 381%, 60°C: 400%.
Crack binding Covers hair cracks up to 1.20mm.

Application Note

  1. 1) Ensure all surfaces are clean and dry prior to application. Remove any dust, dirt and flaking parts.
  2. 2) Stir well before application.
  3. 3) Fill the bridging gaps and hairline cracks with a suitable putty. Application temperature should be between 5 - 35°C.
  4. 4) Apply 2 coats using a good quality brush, roller or by airless spraying without thinning. Ensure corners and edges are adequately covered. Additional coats should be applied 24-36 hours after the previous application.

Attention: The Elastomeric Roof Paint can be applied directly on exterior horizontal (e.g. terraces) and on inclining surfaces. New substrates from cement or masonry should have cured for more than 3-4 weeks before primer application. Adverse conditions during or immediately after application may affect the coating’s properties. The paint has a spreading rate of 2 ± 1 m2/L.
