Socket Plaster Guide - Step by Step

Socket Plaster Guide - Step by Step


The lower part of the house is exposed to extreme loads exposed, therefore a special base plaster must be applied exactly according to instructions.

1. Choice of base plaster

The base is the lowest part of the house. It includes the foundation in the ground and the aboveground part up to the area where there is normal plaster. In this area, the masonry is particularly vulnerable to ground frost and squirting rainwater. It requires protection.

Special paints, covering the area or plastering with a frost-resistant, abrasion-resistant and vapor-permeable exterior plaster are possible. He should not contain lime as a binder. Lime cement plaster is not suitable for the base area.

Important: Depending on the insulation system, only certain products may be used.

2. Estimate Material Requirement Instead of Costing

It is not absolutely necessary to precisely calculate the material requirements, since most DIY stores take back unopened packages. It therefore makes sense to estimate the amount needed roughly and to buy generously. The height of the pedestal in meters multiplied by the size of the house in meters gives the number of square meters to plaster. Since the yield is indicated on the packs, the determined value is sufficient to estimate the amount of material required.

As a rule, the reinforcement filler and the base plaster are required. Furthermore reinforcement fabric is needed. This is usually available in different widths. Ideally, it is as wide as the socket is high. With a base of four square meters, the putty costs about 20 euros, the socket plaster about 70 euros and the fabric about 15 euros. On tools, there should be a spatula, trowel, wire brush and a utility knife, as well as a vessel and agitator for mixing plaster and putty.

3. Instructions for Necessary Preliminary Work

Although only the above-ground part gets a base plaster, it is recommended to dig the soil about two centimeters deep. Usually there is already a gravel bed around the house. It is sufficient to push the gravel away from the house wall.

Depending on the insulation system, a part of the insulating material is visible below the facade plaster. This is cut off with a sharp knife and removed. Of course, the insulation of the socket can not be removed. It must remain undamaged. It makes sense to turn the base and roughen it with a wire brush.

4. Attaching the Reinforcement Filler and Fabric

Since there are both different fillers and different fabrics, it is particularly important to read the manufacturer's instructions carefully. This is especially true for the mixing of the mass. As a rule, apply a layer of putty on a few meters, press the fabric in and smooth the surface. This mass now has to dry for a few days.

5. Clean the base and finish the work.

If the choice has not been made on finished plaster, then the manufacturer's instructions for mixing must also be followed. The application of the base plaster is simple, the mass is applied with the trowel on the hardened filler and immediately pulled smooth. A uniform job without gaps is important, so that later no water runs behind the socket plaster. Water behind the plaster will cause frost damage in winter.

After the plaster has completely dried, the soil or gravel may be pushed all the way back to the house. The masonry is now protected behind a safe layer of plaster.
