If you have to plaster cable slots, the correct procedure is essential. Plastering the slots protects against direct contact with the cables so that they do not become a hazard.
Materials and tools
Plastering cable slots is not a difficult matter as long as you have the right utensils at hand. They enable an effective process and a satisfactory result. The following list has all of the necessary materials and tools you will need to plaster the cable slots:
- Adhesive plaster
- spatula
- Smoothing trowel
- spray bottle
- hammer
- chisel
- bucket
- optional: sponge or felt board
- optional: pliers
The adhesive plaster is very important, as it is compared to
other guys don't shrink. The plaster with which you fill the slots must not shrink, otherwise bumps will appear in the wall after drying. Adhesive plaster is known under the name Rotband, under which a product from the manufacturer Knauf is also sold. For this reason you get the same type of plaster of paris under both names.Tip: If the slots are more than two centimeters wide, it is much more difficult to plaster them safely. In this case, use so-called putty cloth tapes, which bridge the large gap and thus make it easier to apply the plaster.
preparation
In most cases, cable slots cannot be plastered immediately. If the cables have been laid successfully, there will be surplus
Materials that have to be removed beforehand. This is necessary because otherwise the plaster cannot be applied smoothly and closed. Excess nails and an electrician's plaster, which make it much more difficult to apply, are removed. Just use the hammer for the nails. Fold the nails over or use the other side of your head to pull them out of the wall. Pincers also do a good job here. The electrician's plaster, on the other hand, is carefully removed with a hammer and chisel. Last but not least, be sure to turn off the fuse in the room as you will be working in close proximity to cables.
Plastering cable slots: Instructions
When plastering cable slots, it is important that you proceed quickly and purposefully. Since the plaster of paris used can only be used for a period of about ten minutes, you should only mix small portions. You can find out how to mix and plaster with the following instructions:
- Check the mixing ratio
- is specified by the manufacturer on the packaging
- Pour the required amount of water into the mixing bucket first
- Gradually add adhesive plaster
- let it sink in
- then stir well
- it must be of a smooth consistency
- Moisten the cable slots well with the spray bottle
- the moisture makes the plaster easier to apply
- Pour the filler onto a smoothing trowel with the spatula
- Insert it directly into the cable slot with a little pressure
- wipe down
- proceed in sections
- then smooth it out
Depending on the length of the cable slots, you may have to mix the filler several times. Let the plaster dry and then check if you need a second coat. It can happen, for example, that the amount applied was insufficient and has sunk into the slot. A second layer therefore doesn't do any harm. If, on the other hand, the plaster has not yet dried, you can use a felt or sponge board to work the slots.
Tip: If you don't have a spray bottle on hand, put a little water in a bucket and equip yourself with a thin paintbrush or sponge. You can also apply the moisture you need in this way.
