Dr. Fixit Fastflex is a two component cementitious coating, composed of high quality cement, properly selected & graded fillers, additives and liquid polymer. It is suitable for achieving waterproofing for the water retaining structures such as swimming pools, water tanks, reservoirs, other wet areas, etc, because it provides
strong bonding, good waterproofing and excellent resistant to hydrostatic water pressure by forming highly elastic seamless coating over the applied concrete or masonry surfaces.
Areas of Application
Any concrete, cement or masonry surface that is subjected to damage from moisture.
<li> Swimming pools, water tanks and reservoirs.</li>
<li> Concrete roofs, basements, and basement walls and lift pits.</li>
<li> Concrete foundations.</li>
<li> Parking decks.</li>
<li> Bathrooms, toilets, sunken portions, balconies, planters, etc.</li>
<li> Podiums.</li>
Features & Benefits
<li> Elasticity - Highly elastic film formation which accommodates thermal movements.</li>
<li> Permeability - Impermeable to water providing excellent waterproofing property.</li>
<li> Water pressure - High film built-up to withstand 10m hydrostatic pressure without any leakages.</li>
<li> Application advantage - Can be applied on damp surfaces leading to wide range application and instant remedy from moisture.</li>
<li> Bonding - Excellent adhesion to concrete and masonry substrates hence longer life.</li>
<li> Drying - Quick drying after application & user friendly, faster application.</li>
<li> Seamless coating – Forms seamless coating without any joints, prevents water leakage.</li>
<li> Toxicity – It is Non-toxic and free of VOC .</li>
<li> Ease of application - Easily applied by brush, roller or spray.</li>
Method of Application
1 SURFACE PREPARATION
<li> Surface under treatment should be sound, clean and free from dirt, oil and other loose material</li>
<li> Masonry surfaces should be fully cured (minimum 28 days) prior to application.</li>
<li> All surface cracks, undulations and voids must be repaired appropriately before application</li>
<li>Surface must be in SSD condition prior to application.</li>
2 MIXING
<li> Use slow speed mechanical mixer, add powder component slowly to the polymer in a clean container</li>
<li> Stir till smooth and homogeneous slurry, without any lumps, is achieved</li>
<li> Allow the mixed slurry to stand for 5-10 minutes for releasing trapped air during mixing.</li>
3 APPLICATION
<li> Do not dilute with water</li>
<li> Apply Fastflex slurry by brush, roller or trowel.</li>
<li> Allow the slurry to dry completely for 6-8 hrs before applying 2nd coat.</li>
Coverage
<li>Approximately 5-6 sq.ft in 2 coats at 1.5 mm DFT</li>
<li>coverage may vary depending upon the nature and texture of the substrate</li>
