Tikkurila GrafoTherm is a one-component water-based anti-condensation coating for steel roofing sheets, steel structures and other metal surfaces, where condensation and dripping-water problems occur. It is also suitable for mineral walls and ceilings.

Tikkurila GrafoTherm is composed of millions of micropores in the sizes 0.1–100 microns. They form a multi-layer, porous texture with excellent moisture absorption capacity. Evaporation occurs faster than with conventional coatings due to the microporous structure, which breaks the water surface tension and spreads the moisture over the coating.

For industrial and professional use only.

• Quick Drying - Touch Dry in 1-2 Hours @20°C
• Evaporation occurs faster than with conventional coatings due to the microporous structure

Surface Preparation

• Oil, grease, salts and dirt are removed by appropriate means (ISO 12944-4)

Zinc And Aluzinc Surfaces:

• Sweep blast-clean with mineral abrasives, e.g. quartz sand, to an even roughness (SaS, SFS 5873)
• If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with PANSSARIPESU detergent

Aluminium Surfaces:

• Sweep blast-clean with none-metallic abrasives to an even roughness (SaS, SFS 5873)
• If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with MAALIPESU detergent

Primed Surfaces:

• Industrial coil primer on the backside of the steel roofing does not require any special preparation
• Grease, salt and dirt are removed from the surface by appropriate means
• Repair any damage to the primer coat with Temaprime EE or similar product
• Note the overcoating time of primer

Stainless Steel:

• Roughen the surface by grinding or sweep blasting using non-metallic abrasives

Previously Painted Surfaces:

• Old painted surfaces should be roughened to ensure adhesion

Primer

• Temaprime EE
• Temacoat RM 40
• Temacoat Primer
• Temacoat GPL-S Primer

Application

Application Conditions:

• All surfaces must be dry
• The temperature of the ambient air and surface should not fall below +10ºC during application and drying
• Relative humidity should not exceed 80%
• The surface temperature of the steel should remain at least 3ºC above the dew point
• The temperature of paint itself should be above +15°C for proper application
• Good ventilation is required in confined areas during application and drying

Application:

• By airless spray or when not possible by brush or roller
• Mix the paint thoroughly before use
• For spray application the paint can be thinned 0–5%
• Airless spay nozzle tip 0.027”–0.029” or bigger and nozzle pressure 150–180 bar
• Spray angle max. 400º
• Use a spray unit with an output of minimum 2.7 l/min
• If sieves should be used, use a course sieve, e.g. 30–60 mesh

Do not overcoat with any other type of coating as it causes a loss of the absorbing properties of this product.
