Experienced in new house decoration. Diatom mud or wall?

It is very good to say that diatom mud is used to decorate the wall. You should know that the largest area in a house is the wall, and the decoration of the wall is very important. Latex paint is the most commonly used wall decoration material on the market at present. So how do you judge that diatom mud is suitable for your home?

1. Basic functions (characteristics) of diatom mud

The industry standard of diatom mud clearly stipulates its basic functions, and stipulates that diatom mud needs to meet four points: usability, decoration, functionality and environmental protection.

1. Availability

Must have a certain bonding strength, therefore, the material must be added with inorganic gelling substances. It has certain temperature and humidity resistance, which mainly ensures that diatom mud will not age and fall off due to periodic temperature and humidity changes in the actual environment after being installed on the wall.

2. Decorative

The color of diatom mud is mainly achieved by adding natural inorganic pigments, and its texture pattern can be made by various tools and technologies. Rod-shaped soft clay has strong plasticity and can produce various texture effects.

3. Function

(1) hygroscopicity: wa( 1x 10-3kg/m2) hygroscopicity wa≥20 for 3h; Moisture absorption wa≥27, lasting for 6 hours; 12h moisture absorption wa ≥ 35; 24h hygroscopicity wa≥40

(2) Discharge: WB (1× 10-3kg/m2) is discharged for 24h, WB≥wa×70s product moisture content, △ω [(kg/m3) /0. 19 average volume moisture content (kg/m3) ≥8.

(3) Formaldehyde purification capacity: purification performance ≥80, durability ≥60.

(4) Anti-mildew: the anti-mildew performance grade is 0, and the anti-mildew durability grade is 1.

4. Environmental protection

(1) diatom mud itself does not contain harmful substances such as formaldehyde and benzene series, but the environmental protection may not meet the standard after adding other substances to make diatom mud soft mud.

(2) standard: the content of volatile organic compounds

Second, the shortcomings of diatom mud

1. It is difficult to handle large areas of stains.

After diatom mud is stained, it should not be scrubbed with water. It is generally recommended to use an eraser. However, if you have a large area of stains, it will be difficult to deal with. Even rubber will destroy the lines and affect the appearance.

2. Not suitable for kitchen and bathroom

Bacterial sludge has strong water absorption and can be used to adjust indoor humidity, but water absorption does not mean waterproofing. Under the action of a lot of water, Bacillus mud will turn into mud, so it is not suitable for wet places, such as kitchens and toilets.

3. The price is relatively high

The price of diatom mud is relatively high. Generally speaking, it takes 3-400 yuan per square meter. For working families, it is best to choose relatively cheap latex paint.
