Primemix RM
PRIMEMIX RM is based on an advanced co-polymer, graded sand and cement along with active ingredients, which when mixed with water produces a high strength waterproofing patching mortar, screed or render. Once applied the mortar has excellent resistance to wash out and cures rapidly to form dense impermeable matrix with high diffusing resistance to oxygen, acid gases and chloride ion.
PRIMEMIX RM can also be used to produce Gunite with enhanced properties for application by wet or dry process allowing high build application with low rebound losses at too water- cement ratios. The enhanced properties ensure high adhesion, low shrinkage, excellent resistance to freeze – thaw attack and high flexural and compressive strengths.
Advantages of Primemix RM
- Excellent adhesion in dry, damp or permanently wet conditions to both concrete and steel
- Higher compressive and tensile strength
- High abrasion resistance
- Low water permeability due to continued pozzolanic reactions hence has dense matrix
- Enhanced resistance to freeze – thaw cycles, alkalis and dilute acids
- Low shrinkage
- Non Corrosive to steel with high inherent alkalinity
- Allows easy application to achieve high application thickness in both vertical and horizontal situations. Resulting spray applied mortar have low rebound losses
Advantages over Liquid Polymer Modified Repair Mortar
- As product needs only addition of calculated quantity of water, consistent quality is achieved.
- No need to weigh separately sand and cement for making polymer repair mortar.
- Site tampering with material is not possible, which may be possible with liquid polymer by adding water that is not desirous.
- Exact graded sands are used to get compact repair mortar, which is not possible if different grades of sand are mixed at site.
- Factory controlled quality, hence consisting is obtained for all repair patches, which may not be possible for site prepared polymer modified repair mortar.
- Easy to carry by train, trucks, tempos or private vehicles, without risk of loss and other limitation.
- No need of carrying weighing balance and, water is added on volume basis.
- Small packing of 1kg and 5kg also available, hence no loss of material at site.
