Directions for Use
Tools preparation: cleaning tools including saw toothed plastic scraper, brush ,plastic drum, 30kg electronic scale,rubber gloves and shovel knife.
Construction environment requirement: sealant should be installed under the cleaning environment with 5~40oC relative humidity 35~85%RH.
cleaning of substrates: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 is cleaned by wiping out,cutting,polishing,sweeping,washing,scrubbing and blowing.
If large cracks on the film, sealant should be used for filling of crack ,and filling surface should be scraped with the level of film, after curing depth reach up to more than 3mm, the film can be coated on the joints.
prime coat: dilute the coat film into 20-30% solution by using methylbenzene or dimethylbenzene, then brush it a little heavily or scrape it out by saw toothed plastic scraper back and forth in horizontal and vertical directions more than 6 times each direction,then brush the abnormal protuberance and saging place ; The coat is brushed homogeneously , the surface of coating can't expose the substrate in 3-5mins , the thickness of film coat is less than 0.5mm. The function is to clean the dust and air absorbing on the surface of substrate, improve wetting between coat film and substrate,avoid film bulking and rolling down,improve the adhesion strength between coat film and substrate, and avoid needle holes and bubbles coming out on the film .
After primer fully cured, coat film start application.Pour the film on the base coat,apply the film by using the saw toothed plastic scraper and brush, scrape it out back and forth in horizontal and vertical directions more than 6 times each, then brush the abnormal protuberance and saging place, the surfacte of coating can't expose the base coat in 3-5mins. Don't apply part of coat film too thicky, after coating cured to form the film (about 24 hours), then coat next, each direction of coating should be vertical with the forth coat. In general, it should be applied 2-3 times when the thickness of coat film less than 2.0mm.
Protective coating construction: if needed, protective coating can be applied on the surface of film coat.
Cleaning of tools: the tools can be put in methylbenzene or dimethylbenzene(strictly prohibit it to put 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.
Usage and Packing
Coat film thickness is 1.00mm, usage is 1.3kg per square meter
Packing: 5kg/ metal bucket, 20kg/metal bucket
Attention of operation Forhibit the alcohol mixed in the products, the coat film will lose efficacy seriously; All tools can't be used if has alcohol without being cleaned; Film coat thickness is about 2mm, special part should be more than 2 mm; When apply film coat, the coating layer's drainage system should be smooth to ensure no ponding on it during film coat construction; Film coat should be avoid ponding,pollution and Collision damage before touch dry, pls don't construction operation on the coat film before it fully cured (about 24 hours generally);
The organic solvent used for primer and cleaning the tools,and tiny solvent contained in the film coat, all of these are unloading inflammable and explosive goods, the construction environment should be in good ventilation.
Write down construction record truthfully befoe operation; for the special project, please strictly operate according to Sepna supplied construction technology
The cured sealant is non-toxic,the sealant before cured should not contact with eye and skin.
If contact with skin, wash immediately with plenty of alcohol and soap. In case of accident or if you feel unwell, seek medical advice immediately.
