Applications
Plasters and Renders
Many plaster and rendering contractors now realise the advantages of using ADFIL's specifically designed range of polypropylene fibres.
The addition of polypropylene fibres provides an effective way of completing high standard projects more economically.
Potential Problems
The migration of calcium hydroxide, a by-product of cement hydration causes efflorescence or lime bloom. Calcium carbonate crystals formed on the surface between the calcium hydroxide and carbon dioxide leave unsightly staining on the finished product.
Plastic shrinkage cracking occurs on surfaces where the rate of evaporation exceeds the rate of bleed. Such a situation is the cause of stresses in the cementitious material, which lead to hairline cracks, often penetrating the full depth.
When renders and plasters are applied to a backing material, on occasions there maybe problems with the cementitious material bonding. This lack of adhesion can lead to hollowness, which in turn leads to cracks and any impact will bring about delamination of the material.
