Does the foam cement on the floor need to be retreated when the house is being renovated?

The foam cement laid on the ground, which plays the role of heat insulation and sound insulation, should be retained. As long as the surface dust is cleaned, you can lay cement mortar leveling, and stick to the floor tile or wooden floor.

Cement foam is actually a kind of foam concrete, which has begun to be used in some places, but it has not yet been promoted, it is a relatively new process, the foam added to the cement is not our common foam, but a foaming agent, foaming agent and cement will form a lightweight material containing foam inside after mixing evenly, it is very convenient to use, mainly used to brush the wall, make the ground and bricks.

Foam concrete has many advantages, foam concrete is relatively light, which can be used to the place where there are requirements for load-bearing, and foam concrete is porous, which has the function of thermal insulation, usually with air conditioning and heating are relatively insulated, porous can also absorb noise, foam concrete is a good material.

Foam concrete is a new type of lightweight thermal insulation material containing a large number of closed pores formed by the foaming system of the foaming machine to fully foam the foaming agent mechanically, and evenly mix the foam with cement slurry, and then carry out cast-in-place construction or mold forming through the pumping system of the foaming machine.

The basic raw materials of foam concrete are cement, lime, water and foam, on which some fillers, aggregates and admixtures are added. Commonly used fillers and aggregates are: sand, fly ash, ceramite, gravel chips, expanded polystyrene, expanded perlite, benzene degram fine aggregate, commonly used admixtures and ordinary concrete, water reducing agent, waterproofing agent, retarder, coagulant, etc.

There are two production methods of foam concrete: wet mortar method and dry mortar method. The wet mortar method usually mixes cement, sand and water into mortar in a concrete mixing plant, and transports it to the construction site with a truck mixer, and then adds the separately made foam to the mortar, and the mixer mixes the foam and mortar well, and then injects the prepared foam concrete into the pump truck for transportation or direct construction on site.

The dry mortar method is to transport each dry component (cement, fly ash, etc.) to the construction site through bulk transportation or transmission system, the dry component is mixed with water at the construction site, and then the foam made separately is added to the mortar, and the two are mixed in the homogenizer, and then used for on-site construction. If necessary, you can go to the point of leopard to grab an order to see if there is a suitable one.

The cost of floor glue is more than 30 per square meter. There is also that kind of children's puzzle foam cushion, but it is only suitable for the bedroom, and the living room is not very suitable. Kitchen and toilet can be pasted with non-slip floor mats, ** are sold.

But you have to have a flat concrete floor and don't drop sand to use these. There is also the kind of red carpet that is laid in front of the mall, which is not expensive. You can think about it all.

However, it is recommended to renovate the house.

It doesn't need to be removed, and the foam doesn't hurt. Generally, there is a layer of foam under the floor heating, which is used for heat preservation.

Floor mopping is a small hole where moisture penetrates into the concrete floor when mopping. And there is air in the holes. There is a phenomenon of foam on the cement surface of mopping the floor.

It is collectively called benzene board, which is used for heat preservation. When the benzene board is attached to the wall, it is easy to have interlayer and air sound when the treatment process is not good.

EPS finished components, generally used for building line feet and decorative column modeling.

Acoustic panels. , to make a simple house.

Traditional wall decoration process: the first step: base treatment (eradication of walls, cement mortar powder walls); Step 2:

Brush the interface agent (avoid hollowing and insufficient adhesion); Step 3: Wall leveling (the error is 5-8mm for the wall, the gypsum batch wall, the yin and yang corners of the wall are usually not straight); Step 4: Scrape putty (to improve wall quality, waterproofing, etc.) before coating, if wallpaper, a base film layer is required; Step 5:

Sandpaper the walls while avoiding sand marks and dust adhesion; Step 6: Apply the primer (the flaws are obvious after the primer, and further leveling and polishing are required); Step 7: Apply the topcoat (brush, roller, spray, etc.).

Foam brick walls need to be hung with steel wire mesh on the wall to approve cement mortar.

Foam adhesive should not be used to bond cement floors to tiles because it is not strong enough.

Foam adhesives are suitable for self-adhesive and inter-adhesive with rigid materials for a variety of soft materials. Such as foam, sponge, leather, PVC soft materials, KT board, plastic film, soft fiber, etc. and hard materials, iron sheets, aluminum plates, organic boards, glass, wood, stone, ceramic tiles, etc., suitable for the use of blackboards for steel structure engineering and supplies of decoration and advertising companies.

No, because the foam glue is not hard enough, it will loosen after stepping on it for a while.

No. Tile adhesives should be used.

1. Foam adhesive is suitable for self-adhesive and mutual adhesion of various soft materials and hard materials. Such as foam, sponge, leather, PVC soft materials, KT boards, plastic films, soft fibers, etc. and hard materials: iron sheets, aluminum plates, organic boards, glass, wood, stone, ceramic tiles, etc.

2. Tile adhesive, also known as tile adhesive or tile adhesive, is divided into ordinary type, polymer type, heavy brick type, mainly used for pasting ceramic tiles, face tiles, floor tiles and other decorative materials, and is widely used in interior and exterior walls, ground, bathroom, kitchen and other building finishing decoration places.

If the thickness of the paste is pasted, however, it is best to choose a B glue for the plate, and the effect will be better.
