Paint and coatings, or P&Cs, are finishing coatings for construction applications intended to create a protective/decorative film on a treated surface.
- Protection against corrosion, decay, fungi, pests, fading in the sun, combustion, aggressive chemicals, etc.
- Creating certain sanitary conditions, cleanliness control
- Decorative finishing, attractive appearance, implementation of designer’s creativity
There is a wide range of paints and coatings, including, but not limited to:
- Paints: by composition are classified as limewater colours, distempers, cement paints, water-glass paints, water-dispersible paints, aqueous emulsion paints, latex paints, oil paints, alkyd paints
- Lacquers: applied directly to the substrate or a paint coating in order to improve gloss
- Colorants: tinting/tainting additives to paints and coatings
- Solvents: used to make paints and coatings with required viscosity or properties
- Primers: applied directly to the base surface in order to provide protection and adhesion to subsequent coatings
- Enamels: rich coloured compounds which thicken when subjected to UV light or mixed with hardeners/plasticisers
- Treatment and preservative materials
- Putty: dense compounds used to level a surface and to fill cavities prior to finishing paint or coating
Properly selected paint/coating is the key to good look, robustness and lasting protection of the treated surface of structures or individual elements. The materials may be classified by various criteria.
Intended substrate/base material
- Stone, brick, silicate materials
- P&Cs based on thermoplastic film-forming agents (bituminous varnish, cellulose ether varnish)
- P&Cs based on thermosetting film-forming agents (polyester varnish, polyurethane varnish)
- Vegetable oil based P&Cs (linseed oils, oil varnish, oil paints)
- Modified oil based P&Cs (alkyd resin based alkyd varnish)
Showing through of the base surface
- Paint is an opaque coating that tinctures a certain colour to the surface. Paint consists of a binder, pigments and special additives to render particular properties to the surface (texture, relief, protective ability, etc.)
- Varnish is a transparent material that leaves visible the pattern and colour of the base surface. Varnish consists of a film-making agent, small amount of pigment (as the case may be) and various additives to render special properties
- Waterproof and weather resistant materials
- Oil/fuel resistant materials
- Acid and alkali resistant materials
- Heat resistant materials
- Electrical insulating materials
- Preservative materials
- Special materials: reflective, temperature indicating, anti-fouling, acoustic, etc.
