SurfaPaint ThermoDry® Metals is a water-based and waterproof paint that can be directly applied on metal surfaces for thermal insulation and metal corrosion prevention. It is a unique all-in-one formulation of a high quality PU-modified acrylic paint and SurfaPore ThermoDry®. It can withstand temperatures of up to 150°C and can be used as a tinting base for light shades.

Thermal Insulating Properties

When thermal energy travels through walls and other surfaces, large amounts of energy are required for cooling in the summer or heating in the winter. SurfaPaint ThermoDry® Metals 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.

Photo Poblem-1


Thermal Conductivity < 0,1 W/(mK), (EN 12667:2004) - corresponding value for a conventional paint is 0.50 W/(mk)
Thermal Reflectance >90% Reflection of the IR region of light (ASTM G173-03)
Liquid water permeability “non-permeable” by water according to EN ISO 1062-3:2008

How To Prevent Rust
Appliation Note

  1. 1) Ensure all surfaces are clean and dry prior to application.
  2. 2) Remove any loose rust from metal or flaking paint with abrasive paper or a wire brush. Painted surfaces should be sanded prior to application.
  3. 3) Remove any dust, dirt and degrease with white spirit. No primer is required.
  4. 4) Stir well before application. If thinning is required add up to 5% water by volume.
  5. 5) Apply 2 to 3 even coats using a good quality brush, roller or by spraying with a tip of a diameter 1,4mm or more. Do not overbrush. Ensure corners and edges are adequately covered.
  6. 6) Additional coats should be applied 3 hours after the previous application.

Attention: SurfaPaint ThermoDry® Metals can be used directly on all types of ferrous metals for effective corrosion prevention. On non-ferrous metals such as aluminium and on freshly galvanised steel, a primer should be used. The waterproof paint has a spreading rate of 8 m2/L per coat.

Ideal Surfaces for application

All types of ferrous metals, non-ferrous metals such as
aluminium and on freshly galvanised steel.
