DESCRIPTION

Barrier Pro 521 Coating is a single component, latex polymer compound which forms a permanently flexible, elastic, waterproof membrane. Barrier Pro Coating is resistant to hydrochloric and sulphuric acid solutions up to 32 percent. The product is highly resistant to water and salt penetration and the effects of most chemicals. Barrier Pro Coating contains no volatile organic compounds and is flame retardant. Barrier Pro Coating contains a built in biocide and will not support mould growth.

Barrier Pro Coating is ideally suited as a protective coating for industrial applications where moist acidic or alkaline atmospheres exist. Applied as directed, Barrier Pro Coating will protect steel structural members and decking for up to 12 years without the need for recoating. 

Typical applications would be steel mill clean lines, electroplating shops, pulp and paper mills and mine installations.

APPLICATION
Barrier Pro can be applied to steel surfaces showing surface rust, provided that the steel is first cleaned using high pressure water blasting combined with  5% bicarbonate of soda  to adjust surface pH. One coat of our Neverox Anti-Rust Emulsion is then applied. After 24 hours, the surface is then sprayed with one coat of Barrier Pro 920 Series Coating @ 80 sq. ft. per gallon using a high pressure airless system. Allow 1 to 2 hours and apply a second coat at the same rate. Airless spray settings: compressed air supply pressure of 800 psi., compression ratio of 28:1, tip size of .025” and a fan width of 8”. Typical airless spray systems that work well with this product are: Graco Bulldog, Graco GMAX II, Titan Speeflow 7900.

Because there are no VOC’s and the coatings are non-flammable, they can be used safely in enclosed areas without concerns about toxicity, fire or explosion.

PRECAUTIONS

Although Barrier Pro 521 Series Coating is unaffected by freezing when cured, the product must be protected from freezing prior to use as it is perishable in the liquid state. Do not apply the product if freezing conditions are imminent before the final cure period of the membrane.

Barrier Pro 521 should not be used in applications where ambient temperatures exceed 130ºF (54.4ºC)

Rubber or nitrile gloves as well as protective clothing, splash goggles and vapour respirator should be worn during application. Barrier Pro Coating is extremely difficult to remove from skin or clothing once it has cured. The product can be washed away with plain water prior to curing. Equipment must be cleaned with fresh water immediately after application.
