Different Paint Types

All paints are not created equal, so simply asking for two coats of paint is like asking for a slice of biltong. Don’t be disappointed if your slice is too small, as you didn’t specify. The same applies for painting projects. Two coats of a cheap, low quality paint will not provide the same coverage or finish as one coat of high quality industrial paint, nor will it last as long. So what determines the quality and durability of a given paint?

To understand what makes up a high quality can of paint, we must first understand that there are four main raw materials used in paints, namely 1) solvents (or water), 2) pigments, 3) resins (binders), and 4) additives.

Solvents refer to various low viscosity, volatile liquids which can dissolve a resin. Solvents include petroleum mineral spirits and aromatic solvents such as benzol, alcohols, esters, ketones, and acetone. Water is used in many paints. The solvent makes up the liquid portion of the paint which makes it easier to apply, but evaporate as the coating dries. A paint with a higher volume-to-solids ratio will contain less solvent and more pigment and resin which form the coating on the wall once the solvent has evaporated and the paint is dry.

Pigments are simply insoluble, finely ground materials that give paint its colour. Titanium dioxide is the most common pigment as it is used make basic white paint.

Resins are used as a binder in paint. Resins can be translucent or transparent, solid or semi-solid. The nature and amount of binder determines much of a paint’s properties, such as washability, toughness, adhesion, elasticity and colour retention.

The last category of raw materials in paint are additives, which can serve many purposes, from reducing the drag on a brush, providing anti-slip characteristics, adding texture, etc. There are many different paint additives, such as driers, anti-settling agents, anti-skinning agents, defoamers, silica (or sand) for texture, mildewcide, perfumes and a host of others that enable paint to cover well and last long. Some, like calcium carbonate and aluminum silicate, are simply fillers that give the paint body and substance without changing its properties.

Application of a paint consisting mostly of solvents may be easy, but when the paint dries it leaves behind less of the other raw materials on the walls. This sort of paint may only have a 28-30% volume-to-solids ratio and so when the paint dries the thickness of the paint film that is left on the wall is relatively thin. If most of the remaining materials in that paint are fillers, like calcium carbonate, then your walls may look fine after a two coat application, but the coating will not last very long.

The dry film thickness of paint is measured in microns (µ), which is a thousandth of a millimeter. Many commonly used paints produce a dry film thickness of around 25-40µ per coat, so a two coat application will leave your wall with a film thickness of 50-80µ.

A high quality paint with a higher volume-to-solids ratio will produce a thicker film when it dries. Ideally, the other raw materials, such as the resins, should help to contribute toward a quality coating that will last for a number of years, or even decades.

This is why it is important to specify a minimum dry film thickness (DFT) rather than arbitrarily insisting that a contractor apply two coats of paint.

That depends on a number of considerations including the area to be painted, type and condition of the substrate and how long you would like the coating to last.

Matt and Flat Finish

A non-reflective appearance that helps hide surface blemishes, making walls look smooth. These finishes cover imperfections in surface and application and allow for easy touch-ups, although they tend to hold dirt and are difficult to clean as cleaning can actually remove the finish itself. This finish is best suited to adult bedrooms, dining rooms, formal living rooms and ceilings.

Medium Sheen and Satin Finishes

With its slight gloss, this finish offers the benefits of richer look and actually retains its pearl-like finish once dry. This finish stands up well to washing, although it does not hide imperfections as well as a matt finish and touch-ups will stand out. It works best for high-traffic areas such as hallways, woodwork, childrens bedrooms and family rooms.

High Gloss Finishes

These paints reflect the most light once dry, providing a bright sheen. These durable finishes offer high resistance to moisture and are easy to scrub clean, although they show up every imperfection, require additional prep work and do not allow for touch-ups. This finish is perfect for areas that are cleaned frequently, such as kitchens, bathrooms, utility areas, cupboard doors and trim.

How To Measure Your Interior for Painting

Calculate the area of the Vertical Walls and the linear meters of the Skirting board:-

Step One: Skirting: Simply add up the length of each of the four walls in a room to obtain the total perimeter around the room.

For example, 3.2m + 4.5m + 3.2m +4.5m = 15.4m

There is 15.4 linear meters of standard skirting in the room, less 1m for the door. Skirting normally ranges from 69mm to 140mm thick, with 94mm as the most common size.

If the ceiling has cornices, then this same number can generally be used for the cornices.

Step Two: Wall Area: Multiply the perimeter by the ceiling height to get the total wall area.

For example, 15,4m x 2.4m = 37m.

If the room has several large windows (2m² or more in area) and built-in cupboards, then we would calculate the total area of these and deduct that from the size from the total area of the vertical walls. Also, for simplicity, use 2m² for an average-sized inter-leading single-door. (We generally don’t deduct the area of very small windows as they require additional work of cutting-in around them.)

For example, each windows is 2m² of area, and so is the single-door. We ignore the small window and there are no built-in cupboards. So we can deduct 6m² (2m² + 2m² + 2m²) from the total area, i.e. 37m² – 6m² = 31m².

So the wall area for that room is 31m².

Step Three: Ceiling Area: Return to the length (4.5m) and width (3.2m) of the room that you obtained when calculating the perimeter. Now simply multiply the two together, to obtain the area of the ceiling.

For example, 4.5 x 3.2 = 14.4m². This is the footprint of the room, which we use for calculating the area of the ceiling and of the floor. (See above for linear meters for the cornices).

Step Four: Repeat for Each Room: Now follow the exact same procedure (Steps One to Step Three) for every other room that you would like to have painted.

So that you can add each rooms measurements together.

For example, Wall Area = 31m²(room 1) + 16m² (study) + 28m² (lounge) + 12m² (kitchen) + 6m² (bathroom) + 35m² (room 2) = 127m²

Step Five: Doors and Door Frames: Now run through the house and count any wooden doors and frames that require painting.
