Two-component coating which combines an epoxy resin, a tar and a catalyst. Suitable product to protect steel, concrete and wooden surfaces. Very resistant to humidity; sea-water, acids and alkalis, as well as mineral oils and gas-oil.

It is not suitable for being in contact with aromatic solvents, like xylene, toluene and naphtha.

Fields of Application
It can be used as a primer-surface and/or finishing coat. For protecting tanks, buried pipes, metallic structures, floodgates, tanks located in very humid or strongly contaminated atmospheres. For painting sewer systems and waste water tubes.

DRYING:2 - 3 days
APPLICATION METHODS: Brush, Roller, Spray-gun, Airless (The data quoted are only hints)
Finish:Semi-gloss

Carefully stir the mixture in the pack, preferably with a mechanical mixer. Let the mixture to dry for 15 minutes before using it in order to help to remove air. The surfaces to be painted have to be clean, dry and sound. If exposed to sun light, this product will chalk and lose gloss, until becoming matt. It does not mean that it would lose its anti-corrosive or waterproofing performance.

BARE SURFACES:
Steel: Abrasive blasting up to level Sa 2 ½ of the  SIS 055900 Standard. Then apply, depending on requirements, two or three coats of 833 Epoxy Tar.
​Concrete or wood: Remove dirt and residues of oil or any other pollutant with high pressure air or aspiration. If, provisionally, the blasting is protected with 865 Shop Primer, the surface can be repainted with 833 Epoxy Tar after 2 - 3 hours of its application.

MAINTENANCE OF PREVIOUSLY COATED SURFACES IN POOR CONDITION:
Remove damaged areas, as well as grease residues, dirt, etc. The areas with corrosion have to be blasted up`to level Sa 2 ½ o by means of mechanic cleaning ST3. Patch these areas with 833 Epoxy Tar to level up the original thickness. After 24 hours, apply 2 or 3 coats of 833 Epoxy Tar depending on specifications.
