It is preferred that whenever practical Epidek M153 should be applied directly on to blast cleaned steel to Sa21⁄2. M153 may be applied over an approved high build epoxy primer.

If applied over Macropoxy Blast Primer the primer thickness must be carefully controlled. The target DFT is 25μm but the maximum DFT applied must not exceed 40μm. If a high build primer is required please use one of those recommended on the front of this data sheet.

This material should preferably be applied at temperatures in excess of 10°C. In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential. Substrate temperature shall be at least 3°C above the dew point and always above 0°C.

At application temperatures below 10°C, drying and curing times will be significantly extended, and spraying characteristics may be impaired.

Application at ambient air temperatures below 5°C is not recommended.
If it is desired to overcoat outside the times stated on the data sheet, please seek advice of Technical Team.

Packaging

A two component package comprising Component ‘A’ and ‘B’

Component A (20 litre pail); Containing 12.6 litres base screed unit comprising epoxy resin base, curing agent and fine silica grit.

Component B (nylon sack); Containing 25kg calcined bauxite aggregate (see below).

Pack Size: 12.6 litre unit when mixed
Mixing Ratio: 1.54 parts base to 1 part additive by volume plus silica grit
Weight: 1.84 kg/litre (may vary with shade).
Shelf Life: 2 years from date of manufacture or ‘Use By’ date where specified.

Additional Notes

Drying times, curing times and pot life should be considered as a guide only.

The curing reaction of epoxies commences immediately the two components are mixed, and since the reaction is dependent on temperature, the curing time and pot life will be approximately halved by a 10°C increase in temperature and doubled by a 10°C decrease in temperature.

Calcined Bauxite Aggregate

Four sizes of aggregate are available depending on degree of anti-slip properties required and end use:-
1. Light Aggregate (0.85 - 1.70mm )
2. Medium Aggregate (1.40 - 2.00mm )
3. Heavy Aggregate (1.40 - 2.80mm)
4. Road Aggregate (3.00 - 5.00mm)

N.B. Consumption of aggregate will depending upon screed thickness, efficiency of excess aggregate recovery and recycling. For guidance on quantities of aggregate consult sheet entitled Epigrip M153 Supplementary Information.

Overcoating

If it is felt desirable to overcoat the surface of Epidek M153 Heavy Duty Deck Coating or to mark surfaces with a different colour this may be achieved by the application of a coat of Macropoxy M262 Hi-Build Finish.

Numerical values quoted for physical data may vary slightly from batch to batch.
