​

APPLICATION:

Application should be by competent, trade applicators experienced in 2-pack industrial coatings.

Due to the nature of the materials and strong solvents contained in the product, we do not recommend applying Armaglaze by spray. Spray application should only be carried out by trained operators, after a carrying out a full job risk assessment in conjunction a study of the safety data sheets.

​

Bare concrete should be sealed with ARMAGLAZE SEALER. 

New steelwork should be primed with a suitable anti-corrosion primer.

Apply two coats of Armazlaze by brush or roller to surfaces already sealed or painted after checking compatibility.

On non-porous, hard smooth surfaces, it is necessary to abrade the surface first to improve adhesion. 

OVERCOATING:  ARMAGLAZE should be overcoated after 8 hours and within 24 hours.

After 24 hours, ARMAGLAZE may need flatted down by abrasive sanding before applying a final coat.

​

PREPARATION

Read the Material Safety Data Sheet before use.

Surfaces should be clean and free from surface dirt, dust, grease, wax and millscale.

All loose friable material should be removed and damaged areas made good.

Efflorescence, laitence and mould growth should be removed and treated as appropriate.

After surface preparation, any remaining graffiti marks will be obliterated under two coats of ARMAGLAZE coloured topcoat. Minor residues of graffiti need not be totally removed.

Work in progress must be protected by contractors both from adverse weather and physical damage before use.

​

APPLICATION

Mix ARMAGLAZE Hardner Pack B thoroughly into ARMAGLAZE Topcoat Pack A, wait for 15-20 minutes before using.

Test compatibility on existing paint by applying ARMAGLAZE to a small inconspicuous area and observing that there is no wrinkling, blistering or discolouration.

If in doubt, strip back to bare surfaces and re-seal with ARMAGLAZE PRIMER.

Apply ARMAGLAZE when the air and surface temperature is above 5°C and the relative humidity between 40% and 80%. Cold conditions or condensation may adversely affect the drying time or the appearance of the dried film.

For brush and roller applications, it is important to achieve a smooth, even coating.

Add 5% to 10% ARMAGLAZE THINNERS in small additions to improve “wet edge” time and flow properties.

Do not overload brushes and rollers with excessive amount of product so as to cause runs or ponding.

ARMAGLAZE is a thin film product with a very hard, dense surface finish.

Use short pile, solvent resistant rollers for smooth surfaces.

After applying by roller, lay off by brush for an even finish.

Brushing or rolling should not be so vigorous as to cause air entrapment.

Apply the second coat at right angles to the first. Take care to cover all of the surface irregularities and indents.

Apply at the recommended coverage rates.

For spray work, apply by airless or air assisted sprayers in evenly applied fine mist coats thinned as necessary with up to 15% ARMAGLAZE THINNERS. Airless spray tip sizes: 0.011 to 0.021 inches.

​

GRAFFITI REMOVAL & SURFACE CLEANING

Because ARMAGLAZE is strongly solvent resistant, graffiti damage does not penetrate the dried film.

Removal of graffiti using strong solvents with not damage the protective coating, thus making removal easier.

Surface grime can be removed by washing down with detergent and water.

Graffiti damage should be cleaned off using absorbent cloths or scrubbing brushes wetted with ENVIROGUARD GTi ,our environmentally safer, water miscible graffiti remover,

Many commercial solvents and graffiti removers are available on the market.

It may be necessary to repeat the graffiti removal process for stubborn markings.

“Shadows” left after cleaning dye marker pens can be removed using methanol or thickened bleach.

DO NOT USE METHYLENE CHLORIDE BASED PAINT STRIPPERS.

Wear eye protection and solvent resistant gloves when using graffiti removers.
