Over the past decade, water paints and varnishes – LMB rapidly gone from simple mixtures of several components to the complex chemical compositions, formulation which can total up to thirty components. To provide concise, but detailed review of water construction paints and household use: impregnation, primers, paints and varnishes. Distemper aqueous coatings Water paint without film-(binding provides components of paint with each other and provides a grip on the painted surface) – "Dream" of each paint manufacturers, the cost of this paint a few rubles. Has a sonorous name – distemper paint, used for painting the ceilings in dry areas. Relationship between filler particles and the surface is ensured by tight coupling of particles of irregular shape with each other and a porous surface. In this category fall paint containing a binder and 2%. Silicate paints, impregnation and primer Silicate paints are a special category, because unlike all the other water-based paints are a real solution.

As film-former in silicate paints are the silicates, sodium and potassium. Technical name for these solutions of salts – sodium silicate. Silicate impregnation, primers and paints are widely used in painting the facades buildings, since they have record levels of vapor permeability. The interiors are rarely used, because they have a mediocre performance durability. Latex paint Despite the very wide range of latex water-based paints, principle of nomenclature is fairly simple. Name: ceiling, interior, bathroom (rooms with high humidity) and the exterior – especially arranged in order increasing the content of the binder and harboring pigment. Classification of water latex paints, so rather primitive, but in most cases untrue.
As a binding water latex paints and varnishes contain a dispersion of polyvinyl acetate, butadiene-styrene, styrene-acrylate, acrylate. List is in ascending order of cost and performance characteristics: durability, moisture resistance, durability, and a number of more specific properties. Impregnation and primer based on these binders paint manufacturers also offer impregnation and primer. Impregnating an aqueous solution without the binder fillers and pigments, sometimes impregnating delivered in the form of concentrates. The main purpose of impregnation – to prepare the substrate for deposition of decorative coatings and surfaces to give additional properties: hardening hydrophobicity. The main purpose of the primer – to create an intermediate layer between the paint surface and the upper decorative surface coatings. Using a primer surface enhances decorative and provide the conditions for reliable film formation. Aqueous coatings have recently been to finishing and repair work began to use water paints. As a binder for water use acrylic paints dispersion and polyurethane emulsion or their copolymers. Typically, paints are used for the transparent color of wood: doors, windows, flooring, etc. Sometimes, in paints add a small amount of pigment pastes to make wood a certain tone.
