What is the problem with the uneven color of diatom mud

The uneven color may be due to the wrong method of light collection, resulting in the appearance of different areas of light collection will have color difference, especially when the light is irradiated, the inconsistent light collection will lead to different light refraction, so that the wall visually feels different colors.

Is it natural light or indoor lighting? If there is no spotlight on the TV wall, the lighting is relatively soft, which should be caused by the master's manual problem, and it may be caused by insufficient lighting when the master works overtime. Painters who don't do a good job can also have this problem.

The uneven color of diatom mud may be due to the following reasons:

1. The material itself has floating colors. The final color of the wall is blended by a variety of toners, and various toners, fillers, aggregates, and additives have poor compatibility due to different densities, resulting in thick diatom mud wall coating pigment particles floating, aggregating, separating, and drying, and the coating still produces color differences.

2. The toner pigment is not well dispersed. Powder dispersion is different from latex paint dispersion, and powder dispersion should also add dispersants. The reasonable selection of dispersants, dispersing equipment, processes, etc. are all problems that cause uneven mixing of pigments.

After adding water and stirring to apply the powdered diatom mud with poor pigment dispersion on the wall, it is easy to produce striped color difference and color bands in the direction of painting and brushing.

3. Due to the poor technology of cement-based and putty powder diatom mud, there are problems with the formula, and various hydration and gasification reactions occur in the coating, resulting in whitening and flowering.

4. Due to the large difference in the proportion of water added in the construction, the uneven plastering, uneven thickness, and unskilled construction technology cause different shades of color.

5. The surface roughness and water absorption of the base layer are different, resulting in uneven drying and absorption of the coating, and the alkalinity of the base layer is too large, which is also easy to cause uneven color.

6. Improper treatment of the substrate (such as high moisture content or pH value, alkali return of the substrate, etc.) will cause the diatom mud wall to bloom, return to white, and uneven color.

Summary. Diatom mud is too thin and may be caused by too much water added during construction or poor material quality. The following methods can be taken:

1.Remix: Pour out the diatom puree, re-add the appropriate amount of water and diatom mud according to the correct ratio, and stir well.

2.Add thickeners: You can buy some thickeners that are specifically designed to adjust the viscosity of the paint and add them to the diatom mud according to the instructions.

3.Add adhesive: Add a certain amount of adhesive to the diatom mud, such as wallpaper glue, PVA, etc., to increase its viscosity and viscosity.

4.Use professional tools: If you're working with a sprayer, you can change the nozzle or adjust the pressure to achieve the best results.

Hello dear! It's a pleasure to serve you. The first is that the wall itself is not dry when the diatom nucleus mud is constructed, resulting in uneven color and posture, which needs to be re-constructed.

The second is that the wall has been repaired before, and the water absorption rate of the wall is different, and it also needs to be re-constructed, and the third is like what you said, frozen, the probability of this situation is very small, if it is really frozen, no need to blow or bake, and the weather will recover naturally when it is hot. 1. The construction environment of diatom mud (1) The relative humidity during construction should be less than 80%, and the moisture content of the base surface should be less than 10%, and the excessively humid environment is not suitable for the construction of diatom mud. (2) The environment below 5 degrees is not suitable for diatom mud construction, so it is recommended that wall construction should not be carried out in winter, especially in the north.

3) The construction temperature of the fabric should be -4 -40, and it should be noted in summer, not to be constructed in direct sunlight, and to ensure the shade of the construction area.

The original color of diatom mud is off-white.

Disadvantages of diatom mud:

Diatom mud absorbs water so well that as long as there is water that is absorbed immediately, the diatom mud will really become mud. Therefore, if the wall is dirty, it must be selectively scrubbed with a rag or erased with an eraser, but the effect is average.

The ** of diatom mud is higher, generally hundreds of yuan per square meter, and the good one is several hundred, and the cost is still quite high.

The diatom mud wall is very resistant to dirt, so it is difficult to take care of in the later stage.

Compared with diatom mud and wallpaper, diatom mud is not as colorful as wallpaper, and the shape is a bit monotonous.

Summary. There are many kinds of diatom mud colors, which can be adjusted according to the needs of the owners, the color of diatom mud at the beginning is mainly gray-white, which is the color of mineral essence, but this color will feel too monotonous and unremarkable, so some pigments are added to the diatom mud.

What color is diatom mud?

There are many kinds of diatom mud colors, which can be adjusted according to the needs of the owners, the color of diatom mud at the beginning is mainly gray-white, which is the color of mineral essence, but this color will feel too monotonous and unremarkable, so some pigments are added to the diatom mud.

Hope it helps, thank you. Give it a thumbs up.

Hello, convenient words. Follow me, and feel free to contact me if you have any questions.

What pigments to add.

Do you want to make it a different color?

Because the mud degree is in the color blending of diatom mud, the selected pigments are mainly inorganic metal oxide pigments, such as iron red, iron yellow, etc., and the use of inorganic pigments in diatom mud is also to control the introduction of harmful heavy metals.

Generally, good diatom mud will not produce color difference after painting, but the color difference of diatom mud is divided into several situations:

There is color difference after painting and drying: this situation is the instability of the diatom mud itself, the dispersion rate of the toner is poor, and the mixing time is not enough, resulting in the color difference of the wall. The solution is to stir for a longer time, if it still doesn't work, it is the reason for the manufacturer's toner.

Color difference due to different batch packaging: This situation is because the batch produced by the manufacturer is different, although the color is the same, there will be subtle color difference, and there will be inconsistent color difference on the wall when mixing in separate batches, so it is recommended to mix and stir together;

Repair of the color difference: after a period of time after the new wall is painted, accidentally bumped and repaired, this situation is also difficult to repair consistently, the wall will change slightly after a long time, and the color of the new material painting and the old wall is deviated.

It is recommended to buy diatom mud material toner using natural clay material, which can effectively avoid the probability of color difference. The details of the technology should still be more stable in Japanese diatom mud, such as Wakkanai, Shikoku Kasei and Wabi, etc., and the current domestic market of Lanshe and Green Forest is also relatively mature and stable.
