Area Of Application:
- All new RCC flat and sloping roofs.
- Existing cementitious waterproofing treatments like brick-bat-coba, concrete screeds, acrylic coatings, etc.
Method of Application
Surface Preparation
- Prepare the surface thoroughly by cleaning, washing and removing dust, dirt, oil, grease and loose particles.
- Ensure that the roof slope is a minimum of 1 in 100.
- In existing old terraces such as brick-bat-coba or screeds, the substrate must be checked for its soundness.
Damaged or hollow portions, sharp edges etc. must be cut and repaired with a polymer-modified screed. Surface
cracks must be filled with Crack-X Powder or, polymer-modified mortar in case of wider cracks.
- Bitumen based waterproofing treatments must be completely removed by mechanical scarification or by any
other effective mechanical means.
Application Procedure
- Apply one coat of Dr. FIXIT PRIMESEAL (diluted with water in the ratio 2:1) at the rate of 12-15 sqm per litre. Allow
it to dry for 2-3 hours
- Apply the first coat of DR. FIXIT NEWCOAT at the rate of 2 sq.m. per litre and allow it to dry before taking up the
second and third coats, the rate of application being the same.
- The sequence of colours viz. pink, green and grey can be decided depending on the desired top coat colour.
- In case only two colours are being used, ensure that the colour of the first and the third coat are the same. This
would ensure correct consumption of material that will deliver a total DFT of 1 mm.
- Drying time between coats will be 6 - 8 hours
- Ensure that the primer and the 3 coats of DR. FIXIT NEWCOAT totally achieve a minimum thickness of 1 mm
DFT
- Allow the system to air cure for 7 days.
