The official TDS of RF-8602 covers six major waterproof engineering scenarios: shower rooms, kitchens, swimming pools, garden pools, roof terraces and basements. This article selects three representative large-scale engineering practical cases, records the formula scheme of RF-8602 emulsion matched finished coatings, construction process control, post-construction water resistance test results and long-term operation feedback, intuitively verifies the stable performance of RF-8602 in actual complex engineering environments, and provides replicable construction reference schemes for waterproof engineering contractors and finished coating manufacturers.
A large high-rise residential community in Jiangsu, a total of 1,200 residential units, each equipped with two bathrooms and one kitchen, the engineering contractor requires the waterproof coating to have no pungent odor during construction, long-term crack resistance, and pass the national GB/T 23445 two-component polymer cement waterproof coating standard inspection. The construction period is concentrated in winter, and the minimum on-site construction temperature is close to 0°C, which puts forward low-temperature flexibility requirements for the waterproof raw material emulsion.
Liquid component A: Pure RF-8602 emulsion (57% solid content, standard viscosity 2500 mPa.s);
Powder component B: Ordinary Portland cement + 100–200 mesh graded quartz sand + cellulose ether defoamer, powder-liquid mass ratio 2.2:1.
- Base layer treatment: Repair all wall and floor slab cracks with cement repair mortar, polish and clean the floating ash of the base layer;
- Mixing process: Use electric mixer to fully stir RF-8602 emulsion and powder evenly, no flocculation and precipitation phenomenon in the mixing process, the slurry has moderate thixotropy and no sagging on vertical walls;
- Brushing construction: Cross-brush twice, total film thickness 1.3 mm, shower wall waterproof height 1.8 m, kitchen wall 300 mm above the countertop;
- Curing and acceptance: Natural curing for 7 days after construction, carry out 48-hour closed water soaking test for each household bathroom.
All 1,200 households passed the closed water soaking test without leakage; the construction workers reported no irritating ammonia odor during the whole construction process, and the indoor ventilation time before tile paving was shortened by half compared with the previous project using traditional emulsions. After 3 years of community occupancy, the property department counted only 3 leakage complaints, all caused by post-construction tile damage, no waterproof film cracking and seepage problems caused by the coating itself, which fully reflects the excellent low-temperature flexibility and long-term water resistance of RF-8602 modified waterproof coating.
A shopping mall indoor constant temperature swimming pool in Zhejiang, pool area 1,200 square meters, long-term full water storage all year round, water temperature constant at 28°C, the pool wall and bottom are concrete structures, easy to produce tiny settlement cracks, the owner requires the waterproof material to resist long-term static water pressure, no film embrittlement after years of water soaking, and meet the green environmental protection standards of public places. The project selects RF-8602 two-component flexible polymer cement waterproof coating as the main waterproof layer.
Properly increase the proportion of RF-8602 emulsion, adjust the powder-liquid ratio to 1.8:1, add a small amount of anti-aging filler to the powder component to enhance the long-term water soaking stability of the film.
After the concrete pool base layer is crack-repaired, three cross-brushing construction is adopted, with a total film thickness of 2.0 mm, and a layer of 100 g non-woven fabric is laid between the second and third coats to strengthen crack bridging. After 14 days of full curing, fill the pool with water for continuous 7-day static water pressure test, no water seepage at the wall bottom and internal corner.
The swimming pool operates all year round with full water storage, no peeling, cracking and water seepage of the waterproof film, the film maintains good elasticity under the alternating action of constant temperature water and seasonal temperature difference, and the project successfully passed the annual environmental health inspection of public places, with no harmful substance precipitation detected in the pool water.
A 3-story underground parking lot of a city office building, the underground water level is high all year round, the basement wall bears continuous negative hydrostatic pressure, the concrete wall has multiple settlement micro-cracks, the construction environment is closed and poorly ventilated, and the construction period is in winter with low temperature. The project uses RF-8602 flexible two-component waterproof coating for wall positive surface waterproofing.
RF-8602 emulsion mixed slurry has good calcium ion stability, no demulsification during large-area mechanical spraying construction; the ammonia-free formula avoids harmful gas accumulation in the closed basement construction site. After construction and curing, the waterproof film forms a dense flexible barrier layer, effectively blocking underground water seepage. After 2 years of operation, there is no water seepage and wall surface mold phenomenon in the basement parking lot, and the flexible film bridges the settlement micro-cracks generated by the concrete wall without leakage hidden danger.
- Low-temperature adaptability: RF-8602’s -10°C Tg ensures normal construction and long-term stable film performance in winter low-temperature environments;
- Environmental construction advantage: Ammonia-free formula is suitable for closed indoor, underground and public place construction projects, improving construction acceptance efficiency;
- Wide formula adjustability: By adjusting the powder-liquid ratio of RF-8602 emulsion, targeted waterproof coatings can be developed for indoor wet areas, long-term water storage pools and negative pressure basements respectively;
- Stable long-term durability: The film maintains flexibility and water resistance after years of water immersion and temperature cycle, greatly reducing engineering after-sales leakage maintenance rate.
Three large-scale actual engineering cases fully verify the comprehensive performance advantages of RF-8602 styrene-acrylic flexible waterproof emulsion in different complex construction environments. Finished coating manufacturers and waterproof engineering contractors can refer to the formula matching and construction process control scheme of the cases, formulate targeted construction solutions according to project scenarios, and rely on RF-8602’s stable performance to improve engineering acceptance pass rate and reduce long-term after-sales risks.
