If, taking into account all the recommendations, the choice is made and the desired one is found, then the next stage of work will be the preparation of the surface for applying polished plaster. The first thing to take care of is the cleanliness of the walls. You should free them from dust, oil stains, loose areas. In case of the polished plastering process you will be able to know more info from a professional company like Evoke Polished Plastering. Here are the reasons why you should go for polished plastering.
When choosing polished plaster, it should be remembered that:
- Liquid material is inconvenient in operation, since it is not subject to subsequent dilution with water.
- Polished plaster with large filler is applied only by hand.
- Material with crumbs of different sizes is difficult to apply manually; this can lead to the loss of particles.
- Water-basedpolished plaster is less toxic, but also less resistant to environmental influences.
- The provisions on which it is worth focusing on:
- A coating applied on a dense surface of oil paint, plastic and polyurethane foam will require more time to dry than on concrete or plaster.
- Polished plaster based on water can cause deformation for surfaces made of plywood, wood, fiberboard or particleboard.
- For a surface with defects and defects, a larger amount of material will be required, since the plaster will have to be applied in a thicker layer.
- Water-basedpolished plasters will provoke the appearance of rust spots if applied to ferrous metals.
- Basically, the drying time for all polished plasters is the same. 3-5 hours will be required for preliminary drying, 24-36 hours for full readiness.
- In the first two days, polished plaster is still vulnerable.She will need protection from moisture, mechanical damage, temperature fluctuations and exposure to sunlight.
To obtain the proper result and sustainable high-quality coating, experts recommend using a special primer. The primer creates a layer between the plaster and the base, which increases the resistance of the polished plaster to moisture and temperature fluctuations. Promotes better adhesion of the polished material to the surface, which prevents subsequent peeling and shedding of the plaster. The use of a primer reduces the consumption of the base material, and also creates conditions that prevent the appearance of mold and fungus. For reasons of economy, do not neglect the primer. You will lose more if all your efforts have a sad end – the applied polished plaster will crumble from the wall. As you know: avaricious pays twice.
N application of primer
In contrast to the preparation of walls, both for polished plastering and for conventional, which is practically no different, preparing the surface for priming has a number of features:
In order to achieve uniformity of the coating, it is necessary to have a soil thickness of at least 20 mm.
- When grouting and smoothing the soil requires a stronger compaction, so as not to violate the uniformity of the texture.
- Leveled and rubbed soil is drawn with cells.
- Preparatory layers of the soil, after application, are kept for 7-12 days in a wet state, and are wetted with water at the same time two to four times a day.
