Cement-lime plaster is used for high-quality plaster work on various mineral surfaces (concrete, brick) inside and outside the premises. It is recommended for both traditional manual and mechanized application. After grasping is a solid basis for plaster spackles and interior decorative plaster.
The base shall be dry and strong, without break. Paint, oil or wax stains and any substance that reduces adhesion, weak and degraded areas should be removed. The cleaned base should be dust-free. Areas with evidence of biological corrosion should be treated with antiseptic or mechanically removed. The new brick walls, made up of sill, should be free of dust in front of the plaster. Old brick walls should be cleaned with steel brushes or sandblasting apparatus , impregnate with Scanmix primer and dry at least 2 hours. In preparing the basis, the requirements shall be based on the requirements of Building regulations 3.04.01-87 and State Building Norms of Ukraine V.2.6-22-2001.
Pour the dry mixture into a container with clean water of room temperature in proportion : 0.17 – 0.20l per 1 kg of mixture (4.25 – 5.0 l per sack of 25 kg). Thoroughly mix with mixer or low rotating drill with nozzle up to uniform consistency without lumps and clots.Then let the solution stand for 5 minutes and mix thoroughly again. The solution obtained must be used for 2 hours. Use clean tanks and tools for cooking. The solution mixture is applied to the prepared surface by a drawing followed by levelling and smoothing with graters. When the plaster layer is thick, the mixture is applied in several layers according to the rule “wet on wet». The total thickness of the plaster is up to 20 mm. If the total thickness of the plaster layer is greater than 20 … 35 mm, reinforcing elements ( metal or glass woven mesh). It’s possible to apply a solution or a plaster machine through the nozzle.
Work at temperature of air and base +5 … 30³ and relative humidity of air over 60%. Tools and dishes cannot be used, rust. Freshly laid mixtures must be protected against rain, overheating and direct sunlight.
The solution and water should not be poured out after working in sewer pipes. It is desirable to work in rubber gloves. Contact with the skin or eyes shall be avoided. If the solution is applied to the skin or eyes, it is necessary to wash it thoroughly with water, since the mixture contains cement which, when mixed with water forms an alkaline medium.
