The most important criterion in choosing a material-insulation is its increased thermal resistance. In warm plaster, instead of sand, various fillers with low heat conductivity are used, which makes it attractive for those wishing to make a home really warm.
Types of warm plaster
Among the universal warm coatings is plaster with filler in the form of expanded vermiculite, which is obtained by thermal processing of rocks. It is worth noting the good antiseptic characteristics of this material, which allows it to be used for interior and exterior decoration. Increased hygroscopicity requires careful finishing.
The sawdust base is made in paired with cement, clay and paper fragments, which makes it impossible to apply the mortar to external surfaces. If this compound is covered with concrete or wooden plots, ventilate the room as often as possible so that fungi and mold do not appear.
For indoor and outdoor work is well suited filler polystyrene foam. This is an excellent heat and sound insulation, but the material is flammable. Foam glass is waterproof and fireproof base, shrinkage is absent, additional protection is not necessary. However, the thermal insulation properties are not the highest.
Application and benefits of warm plaster
The area in which this material is used is very extensive: door and window slopes, floor and inter-floor covering, basement , joints of ceilings and walls, internal external walls, joints, water supply risers.
Comparing the warm and ordinary plaster, it is worth noting that the former has much more weight, should be applied by the layer at times in 10 cm. All this tightens the repair work. Also, the work site needs a primer and further decorative putty.
It is worth noting the following advantages: adhesion is excellent, reinforcing mesh is optional, but desirable. It is possible to apply to walls without prior alignment,
Application technology is similar to that used for conventional plaster. Walls are cleaned of debris, it is desirable to treat them with impregnations. Warm plaster can be bought as a finished dry mix. If you want, make it yourself. Directly before application, the working surface must be moistened. One layer should not exceed a mark of 2 cm. After 5 hours, you can proceed to the next layer. The process of complete drying can take about two weeks, but the result is worth it.
