Jotamastic 90WG is available in an extensive range of RAL and British Std colours in a semigloss finish, delivered to your home or workshop for free within 1-2 days. Order online or if your colour is not listed simply e mail your requirements to and a member of our customer service team will respond immediately. It is the lowest priced heavy duty epoxy floor coating with high coverage rates 5-6sq meters per litre at 150 microns dft.

It is an economic heavy duty floor coating system with high coverage rates. It can be applied by up to 300 microns in a single coat by airless spray and in excess of 100 microns by roller. It may be applied by brush for small areas, but care must be taken to achieve the recommended dry film thickness. Allow 4hrs between coats @15c, walk on dry after 8hrs @15c. It may be applied to concrete surfaces as low as -5c although drying and overcoating times will be longer under these conditions.

It is recommended for warehouses, distribution centres, garages, factories, production halls and industrial buildings with heavy forklift traffic and chemical spillages may occur. The surface to be painted should be free of oil grease and other contaminants. Loosely adhering paints should be removed back to a sound surface. Where the existing paint surface is unknown it is advisable to undertake a test patch to ensure the Jotamastic does not affect the old painted surface. For concrete floors which have experience oil spillage it is especially important to remove the oil and grease before painting by scarifying or high-pressure cleaning with detergents like Eco Powerclean. Jotamastic 90WG being solvent based may draw oil embedded in the concrete.

On porous concrete surfaces it is recommended to apply a thinned (10-20% with thinner No. 17) primer coat of Jotamastic90WG to help penetrate the concrete to seal it and provide good adhesion. Once dry apply a full unthinned coat of Jotamastic 90WG to a minimum of 125 microns dry film thickness. In the warmer months Jotamastic 90 may be used as an alternative floor coating.

It is available for Home Delivery in an extensive range of RAL & BS colours in a semigloss finish. *Some Strong Oranges & Yellows Not Available, Check with Avace Customer Service. You can find our full range of colours on our colour chart.
