It is an essential material for necessary pretreatment of cement mortar and putty base surface before scraping putty or painting. Product Usage § Interface treatment: Reinforce the surface of the base layer of the wall, form a film efficiently, and significantly improve the looseness, powder or sand removal of the wall. § Substitute primer: water and alkali resistance, anti-salting, prevention of latex paint discoloration, unique combined sealing and alkali resistance effect of rapid penetration and diffusion and high-strength curing film formation. § Flexible transformation and reinforcement of the base layer: to a certain extent, it can resist the cracking of the base layer and prevent the cracking of the surface layer putty. § As a wallpaper base film, moisture-proof, mildew-resistant, alkali-resistant, easy to refurbish wallpaper. § It is universal for interior and exterior walls, regardless of interface treatment, reinforcement of the base layer, or as a primer. grassroots processing § Thoroughly remove the old coating that is seriously loose and loose powder, desand base layer and peeling and damaged. § The surface of the base layer should be smooth, firm, free of cracks and dry. If there are cracks, please repair in advance. § The substrate should be clean, clean, and free from dust, oil, or other contaminants that could lead to isolation. § In case of high temperature and fast drying base surface, the product can be diluted with 1 times of water and then wetted, but avoid hanging and flowing of open water. Construction method § Open the package and use it directly without diluting. The general loose base layer can be brushed once so that the base layer does not lose powder, which saves labor and time. § For projects that do not have high requirements on the surface treatment of the base layer, it can be diluted with 1 times of water before use to improve the slight powder removal phenomenon. § If primer and flexible anti-cracking function are required, use it directly without dilution, and roll and brush more than 2-3 times. § Use a roller to brush evenly on the wall, avoid missing brushes when brushing, and brush 1-2 more times for uneven and loose base layers. After drying, wipe the wall by hand until the powder does not fall off at all. § When dealing with loose base layers or projects with high requirements for base layers, first dilute this product by 1 time and then roll and brush 2-3 times continuously to completely anchor the loose base layer. The above undiluted product can cure the base surface to form a film. § After rolling and brushing the Primer, the next process (scraping putty, painting or wallpapering, etc.) can only be carried out when the wall surface is completely dry and solidified, and there is no powder drop or softening phenomenon at all. § The Primer should be stirred first or diluted in proportion and mixed evenly before construction. It is normal for the colloid to thicken slightly in winter. After full stirring, the construction will not affect the performance of the product. § Walls that have been rolled over the surface agent should not be sanded. Technical performance: Better than the standard JG/T 210-2018 of Primer for Interior and Exterior Walls of Buildings "Limits of Hazardous Substances in Building Wall Coatings" (GB 18582-2020) "Construction Materials Radionuclide Limits" Class A Standard (GB 6566-2010) health and safety § Please take appropriate skin and eye protection measures. Once in contact with the skin, rinse with clean water. In case of contact with the eyes, immediately rinse with plenty of water and seek medical attention. § This product should be stored out of the reach of children. § Do not swallow. Precautions § The construction temperature should be between 5-35℃. Before construction, the humidity of the wall is <10%RH and pH <10. Do not handle and construct on the wet base, and avoid construction outdoors in rainy days. § It is strictly forbidden to mix with other brands of adhesives, and avoid missing brushes when using. § This product is not suitable for severely loose and damaged base layers, otherwise, it should be thoroughly cleaned and then rolled and brushed. § Store in an airtight container.

Ecological ground reinforcement agent
Blue Star Corundum "ecological ground reinforcement agent", referred to as "ground solid", is a multi-dimensional cross-linking of natural plant glue and imported environmentally friendly polymer resin by our company.
Primer Penetration Type
Blue Star Corundum "penetrating type" Primer is a multi-functional adhesive compounded by our company using unique biotechnology with organic silicon, vegetable glue and other active ingredients. The "penetrating type" Primer mainly plays the role of deep anchoring and loose grassroots . It has super permeability, diffusivity, sealing stability and alkali resistance, and is suitable for cement mortar base surface and putty base surface. The pH value is neutral, which can effectively inhibit the wall problems such as pan-alkali, yellowing, salting out, shelling, falling off, and chalking. No formaldehyde is added in the whole production process of this product, so that users and contacts can truly stay away from harmful substances such as formaldehyde and benzene. Product Usage § Use as an interface treatment agent to improve the looseness, powder or sand removal of walls; § Penetration and diffusion, sealing and anti-alkali effect, alleviating the salting out of pan-alkali, and reducing the yellowing of latex paint; § After mixing with ordinary Portland cement, it can be used as a general binder for composite polymer waterproof membranes such as polypropylene and polyester; § Roll brush on the smooth surface of wallpaper putty, which can be used as the base film for wallpaper paste. Construction method ★Interface processing § Before construction, ensure that the wall is dry, thoroughly remove the severely loose powder, sand-off base layer, peeling and damaged old coating, most new houses scrape a thin layer of putty with good quality as camouflage , should be carefully inspected and removed to eliminate the hidden danger of serious wall problems after newly scraped putty. § Smooth the base layer and clean up the floating dust. Prepare construction tools such as rollers and containers. The containers should be kept clean and free from pollution. § To deal with the loose base layer, first use the "penetrating type" Primer to deeply anchor, and then use the "surface-fixing type" Primer to solidify the surface of the base layer. For projects with high requirements on the base layer, first use the "penetrating type" Primer to brush 2-3 times. After the loose base layer is completely anchored, brush the "surface-fixing enhanced type" or "surface-fixing concentrated type" Primer once to loosen it. The base surface is cured to form a film. § Pour an appropriate amount of "penetrating" Primer into the container, use a roller to roll the Primer in the container evenly, and then use a roller to roll the Primer evenly on the wall. Wait for the first Primer of the roller brush on the wall to dry a little, but when it is not completely dry, use the second roller brush, generally more than 3 times, and then wait for the wall to dry, then wipe the wall by hand, completely. When there is no powder drop or softness, the next process (scraping putty, painting or wallpapering, etc.) can be entered. Otherwise, the Primer should be rolled on the wall again according to the above method until it meets the requirements. § Walls that have been rolled over the surface agent should not be sanded. ★Coil bonding § Mix the "penetrating" Primer: water: ordinary Portland cement (32.5R) in a ratio of 1:3.5:10. First add 1 part of "penetrating type" Primer, then add 3.5 parts of water in proportion, gradually pour in 10 parts of cement while stirring, mix and stir evenly in the mixing tank until it meets the required dryness (not too much dry, preferably slightly runny as a slurry). The mixed slurry should be used up within 1 hour. § Construction on the wall: Before construction, the wall must be flat and dry, first lay the waterproof membrane flat on the ground, and use a rubber scraper, a brown brush or a mud palm to evenly brush the mixed slurry on the waterproof membrane ( Wet film thickness > 2mm, dry film thickness > 1.2mm), and then stick the waterproof membrane flat on the wall, flatten side by side to remove air bubbles, and the joints should overlap each other by not less than 10cm (the intersection of the lower membrane surface should be After the glue is fully scraped, close the treated coil according to the cross distance), and it is forbidden to move the coil after sticking. Apply cement mortar on the surface of the paved waterproofing membrane (in the case of outdoor construction, use cement mortar to add river sand of the same weight as cement and mix evenly and then scrape it on the surface of the membrane), so that it can fully penetrate into the fibers of the membrane In the middle, cover and press the joint of the coil and the surface of the coil (wet film thickness > 2mm, dry film thickness > 1.2mm). § Construction on the roof or on the ground plane: first pour the slurry directly on the ground plane and spread it out evenly (the dosage should not be less than 2.5Kg/m2), and then treat the polymer waterproofing membrane according to the method of wall construction and then level it.
