Problems in the construction of the "divided lines" of water-in-water and sand-in-water colorful paints and the division techniques

The stone-like properties of colorful stone-like paint should be composed of paint surface and concave-convex surface or grid lines.

Colorful imitation stone lacquer sand-in-water, water-in-water simulation degree requires a stable finished paint, the particles in it must be transparent, textured, and match the color of the imitation stone properly, and the spray gunner must have the skill to operate on the wall.
Before spraying, the gunner must spray the model, which is consistent with the factory standard model before construction on the wall.

PART 1/Strong stickiness, masking paper is easy to break

Reason: After the middle coat of imitation stone paint is dried, there will be a large amount of emulsion in the middle coat, and the emulsion will penetrate slightly when adhering to the textured paper, which will affect the tensile strength of the textured paper and the viscous com" href="http://">coating online coatingol.
com .

Solution: After the intermediate coating is sprayed, remove the textured paper in about 30 minutes under suitable temperature conditions.

PART 2/The black paint was taken up, and the grid line was broken

Reason: Masking paper is more viscous than external wall putty powder, causing the black paint and putty powder to be taken up by the masking paper as a whole.

solution:

1.
To increase the strength of putty, "putty flushing maintenance" must be in place;

2.
After the black paint is dried, paste the masking paper for protection;

3.
Use better quality textured paper for construction.

PART 3/The paint film is damaged, and there is water seepage at the edge

Reason: After the middle coat of the imitation stone paint is dry, the paint film is thicker and more flexible.
When the textured paper is torn off, the integrity of the imitation stone paint film is destroyed.
When the heat swells and expands, the paint film and the putty layer expand and contract.

Grid shape

In order to make the effect of the exterior wall less rigid, try not to choose square grids during the colorful paint construction, such as horizontal and long grids, vertical grids, and "I" grids are all a good choice.
However, the use function of the building should be considered.
For business units, office buildings should choose a more stable grid design, and residential, shopping malls, schools, gyms, etc.
can choose a more lively grid plan.

7.
Grid position

In order to make the spraying effect of the colorful paint closer to the stone, in principle, the same divisions as the stone can be used, such as the Yin and Yang angle division, the window division, and the building edge division.
However, considering the limitations of the stone, the division of sand in water can not be divided into the yin and yang corners.
It is recommended to divide the division on the side of the window, and be careful not to appear small pieces and small edges as much as possible.

8.
The size of the grid

A reasonable division should be made according to the height of the building.
Generally, the high-rise division should be 1.
5-2 square meters, the multi-storey division should be controlled between 1-1.
5 square meters, and the low-rise division should be within 1 square meters.

9.
The width of the split seam

According to the size of the grid area, the width of the grid seam should be reasonably designed.
Generally, it should be between 0.
8-1.
5cm.
It can also be designed as a horizontal width, vertical narrow, and horizontally narrow grid effect, but try to control the width of the grid seam.
Within 2 cm.
