Blue Star Corundum"Fast-drying mortar" product instruction manual

 

Product Introduction

Blue Star Corundum's "Fast-drying mortar" adopts Blue Star Corundum's unique ultra-fast curing polymer cement technology, fast curing, fast water resistance, consistent hardening inside and outside, good weather resistance, and bonding strength several times higher than the national standard, preventing the wall Empty, cracked. It is easy to construct by leveling, scraping, and raising the yin and yang angles. It can be used for internal and external walls. After the wall is leveled, it can be scraped with fabric putty, painted, wallpapered, tiled thinly, bonded with insulation boards, and plastered with insulation boards. It is especially suitable for rapid construction in humid environments, and the external wall construction can maximize the impact of rain. Strict raw material control and quality management, formaldehyde, VOC, heavy metals and other harmful substances are not detected or nearly not detected. The coarse material of the quick-drying mortar is the bottom layer of the outer wall, and the fine material is the outer wall layer (Fast-drying batter).

 

Construction Method

§ Check the base, deal with hollows and cracks, thoroughly remove the loose base and the old coating that is damaged, powdered, and blistered, clean up oil stains, algal growth layer, remove floating sand and floating ash, salting out, efflorescence Wash it with 5%-10% dilute oxalic acid, and then roll and brush the "interface agent" of Bluestar corundum after drying, which can strengthen the base layer flexibly. Even if it is not the old coating, as long as it is not the base layer made of Bluestar 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 Bluestar Corundum is sealed. For the specific operation method, please refer to the relevant product instruction manual and the "Bluestar Steel Jade Base Surface System Construction Guide". If the temperature is above 30℃, the exterior wall should be sprayed with water before construction.

§ Mortar powder: water = 1:0.25 (1:0.35 for flour paste), the amount of water can be appropriately increased or decreased according to the flatness of the wall. Fill the thick corners and stir to dry, and level the full batch to make it clear.

§ First add four-fifths of the required amount of water into the mixing bucket, then slowly add the mortar powder in proportion, and stir while adding. According to the dryness of the stirring process, gradually add the remaining one-fifth of the water, continue stirring until it is completely uniform, and then it can be used; when using it, it is found that the dry material should be supplemented with appropriate amount of water, and insufficient water will seriously affect the product quality. During the stirring process, scrape the bottom and sides of the barrel at least 3 times.

§ After the mortar powder is added to the mixing barrel, use a portable electric mixer (which can be processed with an impact drill, mixing rod and mixing blade) to fully mix. The mixing effect by hand is not good, unless the amount is very small.

§ Once the mortar powder is mixed with water, it should be used up within 1 hour. If it becomes dry during use, you can add a small amount of water and continue to use it. The material that is about to solidify should not be stirred with water.

§ Under the standard state, Bluestar Gangyu quick-drying mortar can correct the deviation of holes and curves below 20mm (the batter is 10mm) by one-time continuous batch scraping.

§ Blue Star Corundum quick-drying mortar can be used to repair uneven walls or yin and yang corners by scraping with mud palms, first infiltrate a small area for primer, then fill it layer by layer while it is wet, and remove the air and gaps between layers, so that the layers are fully integrated , to achieve the desired thickness. Be careful to flatten the surface as you scrape. Then gradually expand the construction scope to the entire wall in the same way. It can also be pressed by a square (scraper ruler) to better correct the deviation of the wall curve, and it is necessary to press while it is wet. If the ideal flatness is not achieved after one pass, you can re-scrape after the previous layer is dry.

§ After the leveling is completed, the next step of construction can be started after 48 hours of natural maintenance. Before construction, roll and brush the "interface agent" of Blue Star Corundum 1-2 times, which plays a role of sealing and anti-alkali, alleviating ubiquitous alkali salting and cracking of the base layer, and can also brush "waterproof elastic interface agent" to strengthen the waterproof effect.

 

Technical Performance

Better than "Building Putty" standard (Q/20696794-6.01-2021) exterior wall S grade

"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 must be above 5°C, the best construction temperature is 22°C, and the curing time will be prolonged when the temperature drops.

§ In order to reduce potential safety hazards, the total thickness of scraping and repairing on the top and outer walls should not exceed 1 cm!

§ The packaging bag is very easy to leak, so it should be handled with care, to prevent extrusion hooks, 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. If the shelf life is exceeded, the product can still be used as long as it is not damp or agglomerated.

§ This product is stored in a cool and dry environment with a temperature of 5-25°C, without direct sunlight. This product is shipped as non-hazardous.

§ Due to differences in the 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.
