Expocrete mortars are two pack. Each is a different colour to provide visual confirmation of adequate mixing on site. Expocrete cures chemically and therefore does not require the persence of water, solvent or oxygen.
Expocrete products have high compressive strengths, cure with negligible shrinkage and are resistant to chemical and physical attack.
After 48 hours at 20°C Expocrete compounds will have achieved between 60 to 70% of their final compressive strenght.
