Removing old plaster from the walls in the firstThe turn is necessary when preparing the surface for finishing with some material. Removing the plaster is not only a mechanical process. It is important to conduct all stages correctly, only in this case the updated coverage will last a long time and will look worthy. And first of all, of course, you need to figure out how to remove the old plaster and what is needed for this.
Test of strength
At the first stage it is necessary to determine: requires a complete dismantling of the coating, or you can do only a partial update. A small hammer is needed to carry out the work. You need to methodically apply strokes with a tool handle every 30-40 cm of wall and listen. If the sound is deaf, plaster from the walls will have to be removed, since it has already peeled off and can remind of its fragility during the coating. If the sound is sonorous, as if from impact on concrete, it means that the old plaster from the walls will not have to be removed, it is securely fastened and will withstand the weight of the new finish. 
Inspection of plaster for strength can be carried outwith a hammer. Identify potentially dangerous places will help any stains on the wall surface. Wet or greasy marks, visible cracking is a signal to delineate a circle within which the coating needs to be removed. In order to avoid complications in the next repair stages, plaster must be removed within a radius of 30-40 cm from the collapsing site. To work did not have to be remodeled, it's better to immediately dismantle it in the areas where defects are detected (at least to indicate a problematic location). And only later to deal with the removal seriously, because one hammer or spatula will not work. It is necessary to remove all areas with spots of fat. In such areas, a new coating will not be fixed, and a significant stage of the work will have to be remade. Back to contents</a>

The hammer drill must be powerful enough (with the “impact” function and the corresponding sturdy attachment). Such a hammer drill can be rented. It is recommended to use the grinder in especially difficult cases. And it is preferable that someone who already has experience with such a dangerous tool worked with the unit. A diamond wheel must be installed on the grinder. Personal protective equipment should not be neglected. During dismantling, a lot of dust and sand crumbs are formed, from which goggles and a mask will protect. Durable rubber-coated gloves will not be superfluous, which will provide a reliable fixation of the tool. A spray bottle is needed to irrigate the wall. This technique will help to identify poorly fixed locations. In addition, humidification will prevent dust from rising. The ax can be used as a large analog of a spatula for removing individual layers. Back to the table of contents</a>
Removing old plaster
Scheme for removing old plaster. After all the tools have been prepared, you can proceed to the study of how to remove the old plaster. First of all, it is necessary to repel badly fixed areas with the help of a hammer.

Beat blows every 20-30 cm, the more coverage you remove from the walls at this stage, the easier it will be in the future. The entire perimeter should be cleaned with a spatula or scraper. It is necessary to periodically moisten the wall. This will not allow dust to rise into the air and weaken moderately exfoliated areas, also to be removed. If some areas do not yield, it is worth dampening them and leaving them for a while. Such an effect will weaken the layer, and it will easily retire. For particularly strong seats, you need to use a puncher. It must be set to the "kick" function. With it, you can easily remove large layers. The chisel should be placed at an acute angle to the wall and gradually clean the layer. If you need to remove a fairly strong old plaster from the walls, you can use a grinder with a fixed diamond circle. For this, it is necessary to make horizontal and vertical incisions on the wall and remove the separated sections with a hammer or perforator. Insects will weaken the canvas, and removing the plaster from the walls will pass without problems. Back to contents</a>
Recommendations for removing plaster
