How and what to mix plaster? Gravel, sand and? Plasters are applied to a properly moistened base, which is formed by an anchoring spray - a syringe or directly bare masonry. In this case, the plaster mixture is applied in a slightly thinner consistency. When plastering, the mortar is first applied to the depressions and large joints. It is done from the bottom up and if the total mortar layer exceeds 20-25mm, these places are plastered first so that the plasters dry evenly. When applying larger layers of plaster in a single application, their weight causes them to settle and partially detach from the base. This is manifested by waves when tearing and smoothing fresh plasters and by horizontal cracks when drying. These plasters later fall off in the form of oval smaller or larger areas. Plastering is done in so-called trays or with the help of plasterers, wooden or metal. These are guiding pre-prepared surfaces that make it easier to maintain a level surface during plastering. The resulting plasters should be flat and reasonably smooth /tightened/ ready for further treatment such as stucco or colored or hydrophobic coating. #construction #tipsandtricks #traditionalcraft #plasters #historicbuildings
