Primer is used for preparation of various surfaces for carrying out construction jobs. The result of finishing depends on quality of primer. Primers on acrylic basis which have some differences from other types of mixes became one of the most popular materials in the modern market.
Material advantages
Acrylic primer - universal material which has deserved great popularity in the construction market. It is used for covering of plaster, concrete, tree, asbestos, fibreboard, chipboard and other materials. Material allows to make uniform painting of surfaces where there is large number of small time and the bad absorbency of mixes is observed (for example, brick).
Acrylic primer has no specific smell and dries for short period after drawing (about 4 hours). Among pluses the builders also note that at solidification soil can be repeatedly diluted with water and at the same time it will not lose the primary properties.
Acrylic primers get easily divorced and applied, and therefore can be used even by nonprofessionals.
There are two types of acrylic primers: getting and strengthening. The getting primer is deeply absorbed in material that promotes the subsequent uniform coloring of surfaces. Penetration depth of solution depends on its quality and compliance to the GOST standards. The structure is often used on old, fragile surfaces. Depending on type of the carried-out works the strengthening primer which passes air better is also applied and well is suitable for interior finish of rooms.
It is impossible to use acrylic primer for finishing of ferrous metals.
Putting acrylic primer
Before putting material it is necessary to prepare carefully surface on which construction jobs will be carried out. The basis needs to be dried up, cleaned from dust, dirt, oil stains and also to remove layers of old plaster and paint. Primer is applied with uniform layer by means of brush, the roller or the spray.
Before use of mixes it is worth reading the operating manual attentively.
It is necessary to buy primer from calculation of 150 ml on 1 sq.m. Before use material needs to be mixed, and if necessary it is possible to add small amount of water. Mix is applied with uniform layer on surface by means of the roller. Speed of drying can vary depending on type of primer and covering on which it is applied. Acrylic primer can dry in 2-4 hours depending on work conditions. The second layer after which the surface is ready and can be used for processing by other finishing materials is the same way put.
