Construction Method

§ Inspect the wall, deal with hollows and cracks, and thoroughly remove the loose base layer and the old coating that is damaged, powdered, and peeled (slightly loose and powdered can not be removed, and the Blue Star Corundum "interface agent" can be directly brushed on it) , Clean up old wallpaper, oil stains, algae growth layer, etc., remove floating ash, wash out salting and pan-alkali with 5%-10% dilute oxalic acid, and then roll and brush Bluestar steel jade "interface agent" after drying. Reinforce the base layer flexibly, inhibit the salting-out effect of pan-alkali, or brush the "waterproof elastic interface agent" of blue star corundum to prevent the base layer from cracking and water seepage. Even if it is not the old coating, as long as it is not the base layer made of Blue Star Corundum products, it must be rolled and applied with the "interface agent" of Bluestar corundum. There may be wet and water-seeping base layers, and after brushing the "waterproof elastic interface agent" of Bluestar Corundum, the whole batch of "elastic waterproof paint" of Blue Star Corundum is sealed. For the specific operation method, please refer to the relevant product instruction manual and the "Blue Star Corundum Base Surface System Construction Guide".

§ This product is a normal phenomenon due to the use of natural fillers, such as putty, with slight color difference and fine particles, and does not affect construction and other properties.

§ High solid content but good thixotropic performance, the mud palm can be wiped on the wall once or twice, so that the putty can be fully wetted and penetrated into the base layer, resulting in firm adhesion; if you encounter dry materials, you can use your feet Push a few times outside the inner packaging bag, or stir with a trowel to clear it, and you can scrape it freely.

§ After the package is opened, it should be used up as soon as possible. The remaining materials should not be exposed to the air and must be sealed and stored.

§ The thickness of one batch of scraping is not more than 1mm, and the wall curve deviation is more than 2mm. For leveling and raising the yin and yang angles, use Blue Star Corundum "filling king interior wall leveling putty powder" or "leveling plaster" (high requirements for mildew resistance and water resistance) , or more than 20mm thick fill with blue star corundum "quick-drying mortar") leveling. Do not use gypsum powder, talcum powder and other glues to treat the wall. Only after the wall surface is completely smooth and the yin and yang angles are straightened, the "Easy Grinding" interior wall putty paste of Blue Star Corundum can be scraped.

§ After the last putty is dry, the next batch can be scraped. The number of batches varies depending on the flatness of the wall, generally 2-3 times. After the putty has dried, it must be painted within a week. Before painting, roll the Blue Star Corundum "interface agent" (i.e. non-filler permeable primer) 1-2 times, to seal and resist alkali, relieve pan-alkali salting and cracking of the base layer, and prevent latex paint, wallpaper and other surfaces Decorative material discolored.

§ The last pass can be added with two additional polishing, which can obtain better sealing effect.
