INSTRUCTIONS FOR USE
PREPARATIONI
New concrete or cementitious substrates should be at least 28 days old when the moisture content of the substrate should be less than 5%. All laitence
and loose materials must be removed from the concrete surface. If the concrete is strong and sound with light laitence, this may be achieved by
acid etching followed by thorough washing with water. The floor must then be left to dry.
Cracked or damaged concrete or heavy laitence should be prepared by grit blasting or scrabbling until a solid surface is reached showing exposed
aggregate.
All dust and debris should then be removed.
Surfaces contaminated with oil or grease should be flame cleaned or thoroughly washed with a good detergent.

MIXING
Mechanical mixing of resin based materials is preferred whenever possible. In order to avoid trapping air in the material, mixers running at less
than 400 r.p.m. are recommended.

PRIMING
Use only Araldite Epoxy Primer. Pour the entire contents of one pack of primer hardener into the resin and mix until a uniform consistency is achieved. Once mixed apply in a thin continuous film with stiff brushes or rollers. Avoid over application or puddles. Highly porous substrates may require two coats of primer.

LAYING THE SCREED
Araldite Self Levelling Screed is supplied in pre weighed packs in exact proportions. No other materials should be added.
STIR CONTENTS OF EACH TIN THOROUGHLY
Pour the entire contents of the hardener into the resin and mix until uniform. Slowly add the graded filler until fully blended.
After the primer has reached initial cure pour the screed mix onto the floor and spread with a toothed trowel to approximately 3 mm thick. Roll the floor
firmly with a spiked nylon roller to release any trapped air and level any slight trowel marks. Continue to roll until all air has been released.
ANTI-SKID FINISH
If required Anti-skid granules may then be applied to the still wet surface by spray. This gives a non-slip surface. Granule; should be applied 15-30 minutes after laying of the topping to ensure they do not sink but are adequately bound to the surface. Apply approximately 0.1 kg per m2.
