Epoxy self-leveling construction technology

1.

Surface treatment of the base layer

1.

First, remove the floating slurry, dust and garbage on the surface of the concrete.

2.

Use a grinder to remove the laitance to form a rough surface.

3.

Expansion joint treatment:

Open gap treatment: clean up the gaps and garbage-fill the silicone strips-fill the cutting gaps with elastic glue-clean up the gaps around.

Expansion joint filling: clean up the gaps and garbage-fill them with epoxy mortar-stick a layer of fiber cloth along the gaps.

Crack treatment: Use epoxy primer and intermediate coating to seal small cracks.

Treatment of ground cracks and hollow drums caused by irregular settlement: Use a cutting machine to cut V-shaped grooves at the cracks, remove debris, and then inject mortar.

The cutting width is twice the cutting depth.

Construction of epoxy floor primer

Mix the main agent and the curing agent according to the proportion, stir well, and roll it with a roller during the use time.

The roll coating should be thin and uniform.

Third, the coating construction

For epoxy floor intermediate coating batch repair construction, first mix the main agent of the intermediate coating uniformly, then mix the main agent and curing agent according to the proportion, and stir well.

After stirring, add an appropriate amount of fine quartz sand, stir well, and scrape with a trowel to make the surface smooth.
If the batch is uneven or too smooth, and the interval is long, it needs to be hardened and dried before being sanded and cleaned with a vacuum cleaner.
If the paint in the mixing tank is in a hardened state, you must stop using it and replace the mixing tank at any time.
The next step can be carried out after 24 hours.

Fourth, epoxy putty construction

First, fully mix the main agent of the top coat evenly, then mix the main agent and curing agent according to the proportion, and stir well.
After stirring, add appropriate amount of fine quartz powder, stir well, and scrape with a batch knife to make the surface smooth.
The next step can be carried out after 12 hours.

5.
Self-leveling flat paint construction

First, stir the main agent thoroughly, and then pour the curing agent into the bucket containing the main agent to avoid uneven mixing of the materials.
After stirring well, pour it on the ground and use a 2mm trowel to shape it at once.
People can be lightly stepped on 72 hours after construction.

Six, floor marking

Mark the finished floor according to the size, separate it with textured paper, apply the marking paint by rolling, and tear off the textured paper after rolling.
After the construction is completed 12 hours, you can go on board.

Epoxy self-leveling floor paint is a kind of epoxy resin.
It is widely used in building construction and is an environmentally friendly and pollution-free floor paint.

It can ensure that the ground will not be skinned after construction and the flatness and surface strength of the base layer.
It can also fill in the original cuts or cracks of the ground base layer to ensure a self-leveling surface effect and anti-cracking; at the same time, the product can also Carry out high-pressure dust washing on the grassroots level to ensure clean ground

7 Apply wear-resistant epoxy self-leveling surface paint

After the wear-resistant epoxy self-leveling intermediate paint is cured and dried for 24 hours, the trowel coating construction of the wear-resistant epoxy self-leveling flat paint is carried out.
The operation method is the same as that of trowel coating wear-resistant epoxy self-leveling intermediate paint.

2.
8 wax curing

After the construction of the wear-resistant epoxy self-leveling surface paint is completed and fully cured (generally, the topcoat should be applied for more than 24 hours), waxing and curing.
Do not apply water, oil, alkali acid and other chemicals within one week.

2.
Skirting board construction

First remove and clean the original skirting board, and then lay the tiles according to the following construction techniques:

1.
Before the tiles are laid, the ceramic tiles must be selected first, and the specifications are required to be consistent, the thickness is uniform, and there are no missing corners, edges, cracks and obvious defects.
Then clean the surface of the tile and soak it in water for more than two hours, and wait for the surface to dry before using it.

2.
When laying tiles, the tiles should be arranged in staggered seams, and the width of staggered seams is 1/2 of the width of the bricks.

3.
During paving construction, the height of continuous paving should not be too high, and should be adapted to the curing time of the adhesive to avoid dislocation or movement of the lower tiles.

4.
The tiles laid at the sunny corners should be cut into a 45º slope angle, so that a tight seam can be formed when the tiles are laid.

5.
The tile height is the same, the wall thickness is uniform, the bonding layer and the brick joints should be full and dense, and the bonding should be firm, and there should be no looseness, cracks and incomplete curing.

3.
Construction of safety warning line

The painting work of equipment safety warning lines, steps and steel beam oblique support side warning lines shall be carried out in accordance with the "China Safety Facilities Standards".

Safety warning line: The color of the warning line is required to be yellow, and the width of the warning line is 100-150mm.
The warning line shall be painted according to the requirements of the construction unit, including the restoration of the original warning line.

1.
No blocking line (yellow parallel solid line): marked on the entrance cover of the underground facility; marked at the fire extinguisher storage place; marked at the entrance of the power distribution room warehouse next to the plant passage.

2.
Safety cordon (yellow outline solid line): around the generator set (distance 1 m); around the rotating machinery installed on the ground (0.
8 m); in front of the control panel (station) (0.
8 m); in front of the switchboard (screen) ( 0.
8 m).

Note: Warning lines, safety passages and other colored areas are required to be coated with the epoxy self-leveling paint of the corresponding color separately with a separate trowel.
It is strictly forbidden to cover and paint with different colors.
