Polyurethane Waterproof Coating widely used Residential buildings waterproofing coating for basement/construction building
Product Description
SEPNA PU110 is one component self lelveling polyurethane based coating that cures by reaction with atmospheric moisture to form a seamless but flexible waterproofing membrane.
Key Features
1. 100% Pure polyurethane based eco-friendly coating
2. Contains no asphalt, tar or any solvents, no harm to construction personnel
3. Free from pollution to the environment, no toxicity after curing, no corrosion to base material, high solid content
4. One component, convenient for construction, no need of mixing, surplus products should be kept in good airproof package
5. Efficient: high strength and elasticity, resistant to acid and alkali, excellent bonding effect with concrete, tile and other substrates
6. Cost-effective: the coating expands a little after curing, which means it turns a little bit thicker after cured
7. All items tested exceeds national standard GB/T19250-2003
Typical Applications
1. Waterproofing for basement, kitchen, bathroom, underground tunnel, deep wells structure and normal home decoration
2. Leak-proofing and penetrating-proofing of reservoirs, water towers, swimming-pool, for Bath-pool, fountain pool, impounding reservoir, sewage cleaning pool and irrigation channel
3. Used for preventing of leaking, corrosion and penetrating for water tanks, underground Pipeline
4. Bonding and moisture-proofing of various floor tiles, marble, asbestos board and so on

Direction of Use
Tools preparation: clean tools including saw toothed plastic scraper, brush ,plastic drum, 30kg electronic scale,rubber gloves and shovel knife.
Application environment requirement: sealant should be installed in the cleaning condition at 5~35°C relative humidity 35~85%RH.
Cleaning substrates surface:substrate should be solid without loose materials; dry without construction on the wet substrates; clean without dust ,oil,asphalt,tar,paint,wax,rust,Non-Permeable agent,curing agent,release agent and film etc. It should be cleaned by wiping out,cutting,polishing,
sweeping,washing,scrubbing and blowing.
If large cracks on the substrate surface,the cracks should be filled by sealant ,and filled surface should be scraped as the same level as coating. After surface curing depth reach up to more than 3mm, the coating can be appiled on the joints.
The first coating application: first ,brush the wall corner and pipe joints partly ,then using saw toothed plastic scraper to knife-coating in large area. It should require homogeneous without too thick, the thickness of layer should be 0.5mm in general(If too thick, coating layer is easy to emerge bubbles ).
The second coating application: after the fully curing of the first coating layer (about 12 hours),
then knife-coating homogeneously at the second time. The good thickness of the second coating is 0.7mm.The direction of knife-coating should be vertical with the first direction of knife-coating. Please refer to the first coating application in details.
The third coating application: after the fully curing of the second coating layer,then knife-coating homogeneously at the third time.The direction of knife-coating should be vertical with the second direction of knife-coating. Special instruction: the the times of knife-coating should be confirmed based on thickness design of coating, the total coating thickness is 2.0-2.2mm.
Protective layer construction: if needed, protective layer can be applied on the surface of coating layer.
Cleaning tools: dip the tools in methylbenzene or dimethylbenzene(prohibit it strictly to dip in ethyl alcohol solvent), the tools can be used after cleaning the solvent. If long time not be used , it should be washed by alcohol or other organic solvent. The cured sealant should be scraped and teared off.
