Every summer, heavy rains come one after another, bringing a touch of coolness to people, but also bringing new problems to home decoration: if the waterproofing of home decoration is not properly handled, it will cause water leakage, accumulation of water, and moldy walls on the roof, exterior walls, kitchen and bathroom. Such situations will not only bring economic losses to their own families, but also greatly affect people's mood to escape the summer. Home improvement waterproofing is one of the important aspects of decoration, and its quality directly affects the "flood" problem after moving in. Therefore, I recommend a product for you here: Bluestar Gangyu elastic waterproof coating, which will make your life worry-free.

Bluestar corundum elastic waterproof coating is a high polymer two-component cement-based elastic waterproof coating modified by biologically active substances. The powder is mixed with the composite liquid, chemical reaction and biological activity reaction occur, and it can penetrate into the microcapsules of concrete. Holes and gaps form a tight and firm permanent combination and become a tough elastic waterproof membrane, which has a unique effect on the waterproofing of indoor and outdoor buildings such as roofs, exterior walls, kitchen and bathroom.

The following is the detailed construction process of elastic waterproof coating:

1. Before construction

Before the construction of the elastic waterproof coating, it is necessary to ensure that the base layer is clean, smooth, firm, free from sand, powder, dust, oil, shedding and other debris, and sharp protrusions should be shoveled off. Before construction in dry and high temperature weather, wet the base surface with water to no clear water.

2. Remove the protrusions

Carefully inspect the base before construction. The base must be firm, clean, and free of clear water on the base. Sharp bulges must be removed to ensure that the base is flat.

3.preparations

1 Before stirring the elastic waterproof coating, the mixing bucket should be cleaned in advance (it is best to use the original elastic waterproof coating bucket), and there should be no other glue, paint and any pollutants in the bucket, so as to avoid chemical reaction or mixing of various impurities to affect the construction. effect and product quality.

2 Construction tools such as portable mixers, scrapers, brushes, mud palms, etc. should also be prepared on site. When the preparation is complete, pour the component A (composite liquid) into the mixing tank first.

4. Mixing process of elastic waterproof coating

1 Before stirring the elastic waterproof coating, the mixing bucket should be cleaned in advance (it is better to use the original elastic waterproof coating bucket), and there should be no other glue, paint and any pollutants in the bucket, so as to avoid chemical reaction or mixing of various impurities to affect the construction effect and product quality.

2 Construction tools such as portable mixers, scrapers, brushes, mud palms, etc. should also be prepared on site. When the preparation is complete, pour the component A (composite liquid) into the mixing tank first.

Four mixing process of elastic waterproof coating

1. Pour all the component A (composite liquid) into the mixing bucket, and then squeeze all the remaining compound liquid in the bag into the mixing bucket. Be careful not to throw the compound liquid at will.

2. The amount of water added is 5% of component A (composite liquid). Adding too much water will seriously affect the product quality and curing time.

3 3 5% water should not be poured directly into the mixing tank, but should be poured into the inner film bag containing the component A (composite liquid), which is used to wash the residual compound liquid in the bag, and poured into the mixing tank together.

4. Mix the component A (composite liquid) with a small amount of water in the mixing tank with a hand-held mixer.

5 Then slowly pour component B (powder) into the liquid, stirring while pouring.

6 After the initial stirring, use the scraper to scrape off the unstirred material at the bottom of the barrel and the side of the barrel, and then fully stir until it is a paste without particles and precipitation, and the stirring time is about 5-10 minutes.

5. Use immediately after mixing

After the elastic waterproof coating is evenly stirred, it cannot be left standing in the air for a long time and must be used up within one hour. For walls exposed to direct sunlight or particularly dry, wet the base layer with water before construction. Use the gap, you can use the film cover to seal on the barrel mouth, to avoid the surface drying and filming.

Six batches of scratching

1 Primer: In order to achieve the best effect, it is best to use the mud palm batch scraping method, and it is necessary to scrape a thin layer first. Construction should be stopped in case of rain.

2 Repeated rolling and flattening: Repeat rolling during priming to make the elastic waterproof coating fully penetrate and contact the base layer. Immediately after priming, the first batch should be scraped to avoid missing scraping. Pay attention to smoothing the surface while scraping.

Seven, continue to scrape on the dry coating film

After scraping one layer, you must wait for it to be completely cured and dry before making the second layer. Generally, 2-3 layers are scraped, and the final thickness after completion of construction should not be less than 2mm (the thinnest part). It should continue to be scraped to the thickness, and the scraping direction of each layer is preferably perpendicular to each other.

Eight maintenance periods

The last pass should smooth the surface of the coating film. Within 3-4 days after construction, protective measures should be taken, people should not walk or touch it, do not get exposed to rain and sun, and avoid freezing, and the curing period should not be less than 15 days.

Nine. Painting and construction

In places that cannot be scraped, the brushing method can be used for construction. When stirring and brushing materials, more water should be added than the materials used in batch scraping construction, but the excess amount should not exceed 5%. The rest of the method is the same as the batch scraping construction.

Ten Clean tools in time

After mixing or construction, the used mixer, mixing bucket, mud palm, brush and other construction tools must be washed with water in time to avoid sticking.

＊※Tips

1. Construction of joints between boards: The elastic waterproof coating can also be applied to the joints between boards such as wood laminates to fill the gaps between the boards, which can effectively prevent the expansion, deformation and cracking of the joints of the wood laminates.
2. Full batch construction on the board: full batch construction on the board or wood laminate, and seal the board to prevent the board from being deformed and discolored by moisture.
