What is Paint?
All You Need to Know About Paint
Paints are thin coatings applied to surfaces in a liquid form. Paint dries and becomes flexible solids. They have many uses, the protection of the surface from sunlight, dampness, dust, abrasion, and weathering. They provide easily cleanable surfaces that help keep the substrates clean and tidy. They can alter the interior by the use of color, light or darkness, matt or reflective surfaces and not to forget with texture.
Learn all about paint, how it is made, what it is used for and when and where to use it
We underestimate the complexity of paint until we visit the paint store to do some small DIY chores, for a bit of a touch up here, change of wall color there and soon we are laden down with choice.
What sort do we need? What type is already on the walls? What is the substrate that is to be painted, and the list of questions goes on.
That’s usually when we grab the yellow pages and employ a professional. After all they know what they are talking about….and so can you.
After reading through the information provided you will be well versed in the language of paint and then just have to decide on the color.
Application – the order in which things are painted is called a paint system and vitally important in the painting process.
Appplication Tools – brushes, rollers, spray application and pads.
Pigments – important paint ingredient.
Problems – recognizing or avoiding faults like chalking, blistering, checking, cracking, crocodiling or alligatoring, efflorescence and mould or fungus.
Additives – important paint ingredient.
Oil Based – definition of oil based paint. Advantages and disadvantages of using it.
Water Based – definition of water based paint. Advantages and disadvantages of using it.
Spirit Based – definition of spirit type coatings.
Timber Stains – definition of timber stains.
How it is Made a simple explanation of how paint is manufactured.
Special Types these include anti fungus, fire retardant, intumescent, relief texture, heat resistant and multicolored finish paints.
Marbling Effects – an example of using paint effects on a large scale for the floor.
Clear Finishes and Paint
Clear Finishes (lacquer or varnish), are transparent and are used so that the substrate’s appearance is enhanced by the application as well as protected.
They are made up of a binder, solvent and additives.
Paint composition is similar but requires pigments for color and extenders for opacity.
Paint and Clear Finish Composition
Clear Finish = Binder + Solvent + Additives
Paint = Binder + Solvent Additives + Pigment + Extender
Film Former (medium, vehicle, binder)
It is a liquid form
It binds together the components of the paint (or clear finish)
It influences the gloss level, degree of sheen in the film
It keeps the pigment in suspension
It provides paints with water resistant properties
It provides the adhesion of the coating to the substrate by softening the previous dry coat
Examples of binders are:
Drying oils – linseed, soyabean, tung, olive
Natural Resins (either from living or fossilized remains) – kauri, damar, ester, lac, rubber
Synthetic Resins – Alkyd, acrylic, polyurethane, PVA, silicone, epoxy, phenolic
