Conditions for plaster application
In order for the facade to be finishedqualitatively, it is necessary to observe certain conditions. First you need to prepare the surface, or rather, dismantle the old plaster, repair all the cracks, after cleaning the wall of dust and carefully moisturize. The next step is to prepare the mixture according to the instructions given on the package. Only after this it is necessary to apply a ready mix.
Technology of plaster application
The technology of plaster facades suggestsfulfillment of certain conditions. It is impossible to apply such repair actions on a newly erected wall due to the fact that the plaster can crack when the building shrinks. Remember that the concrete surface and gypsum solution react, and the plaster will swell and eventually disappear. In addition, the gypsum, having penetrated the wall, will simply destroy it. In order to prevent this, a lime mortar with a thickness of at least 4 mm must be applied to the wall. The thickness of the layer of plaster applied at a time should not exceed 2-3 cm. If it is necessary to apply a thick layer, this should be done in several stages with an interval of 2-3 days. Grouting the finished surface can begin several hours after the application of the plaster, when the solution has not yet solidified completely. If you start early, the solution will fall off the layers from the wall, if it's too late - the plaster will be too hard, there will be mounds and hollows on the wall and it will not be possible to move the mass from one place to another and thereby level the wall.
Selected on the facade plaster should not only meet the preferences of the owners, but also be environmentally friendly, safe for humans.
