Blue Star Corundum "Interior Wall Glossy Putty Powder" Product Instruction Manual

Product Introduction

Blue Star Corundum "glossy putty powder for interior walls" is divided into ecological type and water-resistant type. It is tough in texture, strong in water resistance, moisture-proof and mildew-proof, and does not crack when 10mm thick. After stirring, the paste is well formed and delicate, and the construction is smooth. It can make up for tiny gaps. The surface is flat and solid, ensuring that the topcoat is firmly attached, smooth and clean. It has good environmental protection, and no harmful substances are detected or nearly undetected.

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 powder may not be removed, and the Blue Star Corundum "interface agent" can be directly rolled 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 Blue Star 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".

§ Dry powder: water = 1:0.4, that is, 1 ton of dry powder can be used to make 1.4 tons of finished putty paste; the amount of water can also be increased or decreased according to the degree of dryness; insufficient water will seriously affect the adhesion of the putty. The mixing tank must be thoroughly cleaned before mixing, and no glue or other additives can be added during the mixing process.

§ First add four-fifths of the required amount of water into the mixing bucket, then slowly add the putty powder in proportion, and stir with a hand-held mixer while adding, gradually add the remaining water according to the dryness, and continue to stir until it is completely uniform If there are no particles, let it stand for 5 minutes and then stir it again, and then it can be used; when using, if the material is found to be dry, it should be supplemented with appropriate amount of water. During the stirring process, scrape the edge of the barrel and the bottom of the barrel at least three times.

§ During the use process, the bottom and edge materials of the barrel must be stirred with the mud palm from time to time to avoid local hardening and drying, and use up as soon as possible.

§ When using, be careful not to contaminate any chemical substances and oily substances. Once the putty powder is evenly stirred, the paste must be used up within 4 hours, and the paste that begins to solidify cannot be repeatedly stirred with water.

§ For ceiling construction, the interface agent must be brushed first, and then the putty powder that has been stirred evenly is scraped with a mud palm to make a base, and then the construction is done in full batches while it is wet, so that the putty powder and the base layer are closely adhered.

§ It can be used for leveling the curve deviation less than 10mm, but needs to be quick-drying. The thickness of one batch of scraping should not exceed 1mm, and the leveling and yin-yang angle of the wall curve deviation greater than 2mm should be made of blue star corundum leveling special putty (anti-mold). With high water resistance requirements, or more than 20mm thick fill with blue star corundum "quick-drying mortar").

§ 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. In the last pass, two additional polishing steps can be used to obtain a better sealing effect.

§ After the surface layer putty is polished, remove the floating ash, and paint it within a week after it is dry. Before painting, brush the blue star corundum "interface agent" with unique penetration and diffusivity 1-2 times, instead of the primer, it acts as a seal and anti-alkali, relieves ubiquitous alkali salting and cracking of the base layer, and reduces the discoloration of latex paint.

Technical Performance

"Limits of Hazardous Substances in Building Wall Coatings" (GB18582-2020)

Class A Standard of "Limits of Radionuclides in Building Materials" (GB6566-2010)

Precautions

§ The construction temperature is above 5°C. When it rains during construction, pay attention to closing the doors and windows.

§ In order to reduce potential safety hazards, the total thickness of scraping and patching with putty on the top of the construction cannot exceed 1 cm!

§ The packaging bag is very easy to leak, so it should be handled with care, strictly prevent the squeeze hook, and strictly prevent moisture. When the packaging bag is opened or damaged, it should be sealed immediately.

§ See the product qualification certificate for the shelf life. After the shelf life, the product can still be used as long as it is not damp or clumped.

§ This product is shipped as non-hazardous. Store in an environment with a temperature of 5-25°C, a humidity of 50-60%RH, and no direct sunlight. Unused powder should be sealed and stored after opening.

§ For details of this manual, please refer to "Blue Star Corundum Putty Product Instruction Manual".

§ Due to differences in use environment, construction habits, and grassroots conditions, the performance may not conform to the design. Please reconfirm the product quality before use, conduct necessary application tests, and use the supporting products of Bluestar Corundum Base System. In the case that the product itself complies with the relevant quality standards, the difference in performance after construction and the quality and safety problems caused by the mismatch of the product system do not belong to the scope of quality assurance of this product.
