What to do if the wall becomes sandy and powdery? Use concrete sanding hardener

- Concrete sanding hardener
Concrete sanding hardener is a new product derived with the development of the market in recent years. This product is directly sprayed on the concrete or mortar surface layer and can penetrate into the concrete. Activates the cement hydration reaction, prompts the calcium silicate minerals in the cement to further separate calcium hydroxide and continue the reaction, effectively improving the surface strength of concrete and mortar. This product is mainly used to remove sand and powder from concrete and plaster layers. This product does not contain benzene, formaldehyde and other organic volatiles and can be used directly indoors.
1. Scope of application:
Concrete floors and walls are sandy and powdery.
, basement, garage, factory building, sand hardening and wear-resistant enhancement treatment.
Repair the surface layer of plastering mortar by sanding and hardening.
, basement garage floor hardening and wear-resistant treatment.
2.
The mechanism of concrete sand hardening agent:
Penetration curing: effective penetration ~3, chemical reaction with substances in concrete to form a dense overall compressive strength increased by 3~, Effectively improve hardness and density.
Wear-resistant and hardening: Effectively improve the hardness, density, and wear resistance of concrete, and prevent and eradicate sanding and looseness on the concrete surface.
Sealing and dustproof: Penetrating into the concrete for deep sealing, extending the life of the concrete floor and making the floor easier to clean and maintain.
Sand treatment
3. Construction steps:
3. Base treatment:
3. Clean the sandy floor to make sure there is no floating dust and keep it dry.
3. For sandy walls, it can be sprayed directly. If the surface has been painted with latex paint or putty powder, it must be thoroughly cleaned before spraying this product.
3. Mixing ingredients:
3. This product may cause precipitation or stratification if stored for a long time. Stir for ~ minutes before using this product.
3. Spraying:
3.3 Ground construction: During ground construction, this product can be poured directly on the ground, and painted with a paint roller or brush. When painting, the sandy ground should be fully absorbed by the paint. The product reaches a saturated state, so that the entire ground is completely soaked, and there should be no accumulation of excess material. For severely sandy floors, this product can be applied continuously for ~3 times to achieve the best hardening effect.
3.3 Wall construction: During wall construction, this product can be poured into a sprayer and sprayed out through the sprayer. When spraying, try to allow the sandy wall surface to fully absorb this product and reach a saturated state. For severely sandy walls, you can spray this product ~3 times continuously to achieve the best hardening effect.
3. Operating temperature:
3. This product is suitable for use in ℃~℃ environment.
3. Maintenance:
3. It is strictly prohibited to carry out other construction and covering on the construction surface within hours after the construction is completed.
3. Dry naturally, no maintenance is required, and the ideal effect will be achieved after an hour.
4. Precautions:
It is strictly forbidden to add water and other solvents to this product during use.
If this product is accidentally dropped into the eyes during use, rinse with clean water in time.
This product is non-toxic, odorless, non-flammable and can be transported as ordinary transportation goods.
. This product is prone to stratification after long-term storage. It needs to be stirred evenly before use.
5. Packaging and storage:
, kg/barrel, kg/barrel.
This product is liquid and should be stored in a cool place with a shelf life of one month.
