Chemsol Chemfast SBR is a ready to use waterproofing and bonding chemical based on styrene butadiene latex. Chemfast SBR is used for repair of plaster and spalled areas and waterproof small areas such as terrace, wet areas, chajja. It can be used for bonding of new to old concrete.
Applications
- Repair of spalled concrete and plaster areas.
- Waterproofing wet areas such as bathroom, balcony and balconies.
- Bonding old to new concrete.
Features
- Easy to use multipurpose product.
- Bonds new to old concrete.
- Fast setting.
- Ideal for concrete modification.
Method of Application
1. Surface Preparation
- Surface should be clean and dry and in sound condition.
- All the surface dirt, grease, loose particles should be removed from the surface. And the surface should be washed thoroughly with clean water.
- All other previous coatings if any shall be completely removed.
2. New Surfaces
- The newly constructed surfaces shall be completely cured before coating application.
3. Cracks and Joint Treatment
- All the surface cracks from 0 - 5mm shall be opened with a 3mm angle grinder.
- The opened cracks shall be cleaned properly and filled with Chemsol Chem Crack Fill a ready to use acrylic crack-filler.
- Cracks more than 5mm should be repaired using polymer modified mortar using Chemsol Chemfast SBR. With a cement sand ratio of 1:3 and polymer content of 10% by weight if cement. Allow it to cure as required.
4. Application
- Mix the bucket contents thoroughly.
- The drain outlets need to be properly detailed with the coating with an additional piece of fiberglass mesh as a reinforcement.
- Mix 1.5 Kg of cement with 1 Kg of Chemfast SBR for coating application.
- Apply 1st coat of Chemsol Chemfast SBR all over the surface. Let the coating air dry for minimum 6hrs.
- Apply 2nd coat of Chemsol Chemfast SBR at an angle of 90o to the first coat and let dry for minimum 6 hrs.
5. Ponding
- Let the system air cure for 3-5 days before pond test.
- Ponding shall be done with water not more than 5 cm in height.
Precautions and Limitations
- Do not dilute Chemfast SBR with water for coating application.
- Keep material closed when not in use.
- Corners, joints and repair areas should be treated with two extra coats.
- Surface must be in SSD condition prior to first coat application.
