Features

• Offers protection against mild chemical exposure, humidity and moisture
• Can be applied as low as -10°C
• Non-yellowing and resistant to frequent cleaning
• Very fast drying and recoating times
• Contains a biocide to protect the dried coating against fungal degradation

Recommended Use

8300 Topcoats should be applied on mineral substrates primed with Primer 8399. Resists mild chemical exposure, occasional product spillage, requent chemical cleaning, intermittent high humidity and moisture. Can be applied on 8399 or well prepared previous coatings. 8300 is classified Class 1 Surface Spread of Flame according to BS 476; part 7 : 1987.

Surface Preperation 

New concrete, plastered or brick surfaces should cure and dry for at least 30 days prior to the application of coatings. Remove grease, oil and all other surface contaminations by alkaline or high pressure (steam) cleaning. Wash total surfacewith plenty of fresh/warm water or high pressure (steam) cleaning in order to remove all remnants of contamination and cleaners ND14 or FK111. Sand previous coatings, which are in good condition to remove gloss and to roughen the surface slightly. Remove non-adhering old coatings. The surface must be clean and dry during application.

Directions For Use 

To ensure homogeneity, coating materials should be thoroughly stirred prior to use.

Application Conditions

Temperature of air, substrate and coating material between -10° and 35°C and relative humidity below85%. The substrate temperature must be at least 3°C above dewpoint. Below0°C the surface should be free from ice.
