MAXEPOX® TAR
EPOXY - TAR COATING FOR CONCRETE SURFACES

Description

MAXEPOX TAR is a two component modified tar epoxy based coating.

Uses

Waterproofing of concrete on bridge decks, foundations, exterior application for water pipes.

Advantages

- Simple and easy application.
- Very good bonding to concrete and metal substrates.
- Good chemical resistance.

Application

Preparation of the surface. The concrete surface must be sound and strong and be clean, free of dust, oils and with less than 4% humidity. The surface must be flat and with slight roughness. Metallic surfaces must be cleaned by sandblasting to eliminate superficial corrosion, and must be degreased.

Mixing of the product. MAXEPOX TAR is supplied in pre-weighed sets. The hardener, component B is poured into the resin, component A. To ensures the proper reaction of the two components, make sure all of component B is added. The mixture can be done manually or using a low speed drill until achieving a homogeneous product in colour and appearance. Avoid introducing too much air when mixing. Once mixed, it is recommended to pour all of the contents into a clean container.

Application. The substrate must be at a minimum temperature of +10ºC and not above +30ºC. Application of MAXEPOX TAR can be done using a brush, roller or air-less gun, in two successive coats with a minimum time lapse of 6 hours and maximum of 48 hours between coats. The pot life at 25ºC is over 6 hours, increasing at lower temperatures and decreasing at higher temperatures.

Cleaning. Tool cleaning is done with MAXEPOX SOLVENT immediately after using .

Cautions

When mixing and placing, do not work without the protection of rubber gloves and safety goggles. If the product comes in contact with the eyes, rinse immediately with abundant clean water without rubbing and seek medical assistance.
In case of contact with the skin, wash with abundant soap and water. If ingested, seek immediate medical assistance. Do not induce vomiting.
Flammable volatile solvents are components of MAXEPOX TAR, so the usual precautions for transport and manipulation for these products should be followed.
In closed areas with little ventilation, provide mechanical ventilation and use appropriate masks.
In case of spillage, retrieve using sawdust, sand or other absorbent material. Do not pour into sewers, rivers, canals or ground.
