White cement is sufficient. The abbreviation of white Portland cement is a white hydraulic cementitious material made of calcium silicate as the main ingredient and an appropriate amount of gypsum to be added to the clinker with the appropriate composition until it is partially melted, and the calcium silicate is used as the main ingredient to accompany the destruction. When grinding cement, it is allowed to add limestone that does not exceed the weight of cement 5.

White cement is mostly used for decoration, and its manufacturing process is much better than that of ordinary cement. It is mainly used to hook the gaps of white porcelain tiles, and is generally not used on the wall, because the strength is not high. It is available at the building materials market or at the decoration material store.

1. If it is a glazed brick, use the mortar you said to hook the joints so-so, this kind of hook is not a real joint, as long as the wall is wiped all over the wall, and then wiped clean with a cloth, this kind of brick is about 23 yuan 1 square meter. If it is an unglazed split brick, there is no need to wash it after pasting.

However, it is necessary to use professional grouts and adhesives, otherwise there will be a white surface phenomenon within 1 or 2 years, and that is because CaCO3 in the cement flows out along the joints and the capillary pores of the bricks, and it is necessary to pickle with grass. This kind of brick must be professionally pasted, and it costs about 32 yuan 1 square meter to paste it.

2. If you can use other grouts to see if you can use other grouts, ordinary mortar is easy to crack, crack and not waterproof. You can take a look at the old buildings in the past, the bricks are all ordinary sand and cement joints, and after a while, the bricks are full of dirt and are not easy to clean.

I don't know if your developer has decided to use ordinary mortar, and I would like to ask you what kind of real estate is there, if you have a joint, see if you can use other grappling mortar, ordinary mortar is easy to crack, crack and not waterproof.

Many people don't know what to do when facing the joints of exterior wall bricks, they haven't encountered them, and they feel that they don't know where to start. Here are some ways to hook the exterior wall bricks.

Construction technology of exterior wall tiles: base treatment, brush interface agent, base plastering, hanging line, brick rowing, pasting, caulking, jointing, cleaning and maintenance.

First, grassroots treatment.

1) During the construction of the structure, the verticality and flatness of the exterior wall should meet the standard requirements. Before the roughness, the concrete protruding from the wall is chiseled flat, and the recess is leveled with 1 3 cement mortar, and the thickness of the leveling should be layered when the thickness is large. When the deviation of thickness or verticality exceeds 35mm, technical remedial measures such as nailing steel wire mesh need to be taken.

2) Before plastering, remove the dust, dirt and oil stains on the surface of the base layer such as brick wall and concrete surface, and nail the steel wire mesh width of 500mm at different interfaces (such as the junction of brick wall and concrete wall).

2. Interface agent.

The interface agent is adjusted into a thick paste in the ratio of 1 4 water and cement and fully stirred evenly, and the interface treatment after mixing can be sprayed or directly powdered by iron plate, with a thickness of about 2-3mm, the temperature is high or dry on the wall, moistened with water before construction, and the interface agent is about 5-15 on the wall (depending on the air temperature), which can be plastered or plastered after the interface agent is completely dry and hard.

3. Grassroots plastering.

Before plastering, the reserved hole of the screw of the pull wall should be filled with expansion agent, and a 40mm deep bell mouth should be chiseled at the reserved hole of the outer wall, and after the expansion agent was instilled, a 20mm thick plugging hole should be filled at the bell mouth. After the interface agent is applied for 10 20min, the bottom layer mortar is wiped in layers according to the requirements, the thickness of the mortar at the bottom is 10mm, and the wood crab is rubbed flat after wiping, watered and maintained every other day, and when it is dry, it can be wiped a second time, the thickness is about 10-15mm, and then it is scraped flat with a wooden ruler, and the wood crab is rubbed with hair, and the next day is watered and maintained. If you need to powder the third time, the method is the same as the second time, until the bottom mortar is flattened.

You post that kind of exterior wall tiles, if it is a whole body, they generally use oxalic acid to wash, and generally hardware stores will sell it.

1. The exterior wall bricks have just been pasted, and if there is cement, the way of direct shoveling can be adopted.

2. Wash the large-area exterior wall tiles with high-pressure water.

3. Dirty small areas should be wiped with toilet cleaners.

4. If it is a whole body, it is generally diluted with oxalic acid and used.

Modern green bricks are generally divided into two categories: antique green bricks and machine-made green bricks. Further down the subdivision, there are wall green bricks, wall bricks, paving green bricks, etc.

Generally, the cleaning and maintenance of antique green bricks are more convenient, and you only need to use a damp cloth or a soaked mop to mop it once to be as clean as new. If the cement stains or rust left over during the construction process are not easy to remove, you can use ordinary industrial hydrochloric acid to mix water in a ratio of 1:3 and apply it to a wet towel to wipe it.

Green bricks are made of clay firing, and the fired goods are blue-gray, with high density, good frost resistance, and no loss of color. Green bricks contain trace amounts of sulfur that can be sterilized, so it also has the effect of health and environmental protection, longevity and longevity. The surface of the commercial green brick is smooth, the four corners are at right angles, the structure is perfect, the compression and wear resistance, and it is an ideal material for the packaging of the wall and pavement of the house.

Green bricks are made of clay mixed and extruded with water, fired in a brick kiln at about 1000 °C, and then cooled with water to make it have better weathering resistance and water resistance. According to the firing method of ancient green bricks in ancient buildings, clay materials are also important materials for modern green brick firing materials.

The exterior wall green bricks should be cleaned after being stained so that they can be clean again and will not affect its beauty, so let's take a look at how to clean them. If there is colloidal sludge or water stains: if it cannot be removed by washing with water, decolorize it with hydrogen peroxide water, or wash it with household dish soap, and then rinse with water thoroughly.

Soil mud and sand: Sweep it clean with a broom, then wash it with water and gently scrub it with the sodium phosphate solution dipped in the brush. If the green brick has cement slurry, it can be fully moistened with water, with 2-4 alkene hydrochloric acid solution, and then rinsed with water sufficiently.

Occasionally, a small stain can be gently wiped off with a clean cloth, and a special detergent can be used to clean the antique bricks. If there are stubborn stains on the surface of the antique bricks that are difficult to remove, clean them with detergents such as acid or alkaline water and organic solvents. However, it is not recommended to use these cleaners frequently to avoid the possibility of erosion of antique bricks.

Tips: The antique bricks are very stain-resistant, and the antique bricks are generally cleaned with water and standard professional neutral detergents. The use of soapy water and a small amount of ammonia can make the surface of the antique brick shiny and bright, and maintain a new degree for a long time.

Just scrape slowly and don't hurt the bricks. Its practical oxalic acid cleaning will not hurt much. It's just that it's not good for the human body.
