What is the depth of the external wall insulation anchor nail into the wall?​​

First of all, when the external wall thermal insulation anchor is installed, the set margin should be greater than two depths into the wall, and should be greater than two margins, so as to ensure the normal use of the thermal insulation anchor and not easy to fall off and damage. The penetration depth of the thermal insulation anchor [Bolt Anchor Spacer] represents the distance directly to the load-bearing wall. The general distance is about 5cm. Different cities need to set different penetration depths.

 

If the ceramsite hollow brick is used as the main building material of the wall, then the use of thermal insulation anchors should be knotted thermal insulation anchors. Also remind the drilling depth, because the drilling depth determines whether the insulation anchor can be safely fixed in, so it should be at least 1cm larger than the depth of the wall, which can ensure the activity space of the insulation anchor [Bulk Drywall Anchors], and A storage space for airborne waste dust.

 

2. What is the external wall insulation process?​​

1. Basic cleaning: that is, clean the surface without dust. Residential Online Network recommends that it is best to paint a layer of paint first, so that its adhesion can reach 0.40, and the amount of water should not be too much, it must be below 10%.​​

2. Mixing of bonding mortar: Mix according to the corresponding proportion. After mixing, wait for about 5 minutes, it will automatically become mortar, and after it becomes mortar, it can be painted on the wall.​​

3. Lay the insulation board: fix the bottom layer of the board first. It is recommended to pop out the wire before fixing to avoid the situation of sticking crookedly. The gap between each board should not exceed 1.5.​​

4. Paste the insulation board: paste the outer board, the gap should not exceed 1.5, the smaller the better. When sticking, you can't press it with your hands. In doing so, the force is uneven, so you need to use professional tools to press.​​

5. Grinding: After the board is laid, you need to wait for a day, and then grind it. It is enough to smooth it, and the dust on the surface should also be brushed clean.​​

6. Construction of reinforcement layer: reinforcement work needs to be done. When doing it, it is best to sprinkle some water, which can play a role in maintenance.
