PAINT TYPES

Acrylic paints [water-based] are water-based and water-resistant. Brushes can be cleaned with water.

Design paints have texture as well as colour and can include suede effect or other textured options.

Enamel paint is a heavy duty paint, popular for door and window frames as it gives a smooth, hard finish.

Epoxy enamel is for metal surfaces.  It protects against rust and doesn’t require a primer.

Gloss paint comes in varying degrees of shine – matt, low sheen, satin, semi-gloss and high gloss shine of a paint.

- High gloss is the shiniest of gloss levels, hard wearing and easy to keep clean.

- Semi-gloss is between low sheen and high gloss.

- Satin is a gloss level similar to semi-gloss.

- Low sheen is a low gloss level, usually used for inside walls.

- Matt is a low-level gloss and the least shiny of all paint finishes.

Ceiling white is the term used for white paint designed specifically for ceilings and formulated for overhead work as it doesn’t spatter and is less messy to use.

Primer is the first coat of a paint job. It protects the surface and provides a good bond for further coats.

Adhesion primer is for difficult surfaces such as shiny finishes, laminates and glass, providing a sturdy base for top coats of paint.

Etch primers are for very smooth metal and etch into the surface providing an effective base for top coats.

Exterior paints are specially designed to withstand tough outdoor conditions and in most cases are self-priming.

Primer-sealer is the paint that combines the properties of a primer and a sealer.

Undercoat is the coat of paint applied after a primer but before the top coats.

Topcoats are the final coats of paint.

Whitewash is made from lime and chalk and is commonly used on exterior brick or stone surfaces.

Binder is an oil-based undercoat used to bind powdery or chalky paint.

Touch-ups are small amounts of paint applied to correct defects or damage to a finished paint job.

WOOD FINISHES

Lacquer is a clear, durable finish usually applied to wood.

Stain is a product that changes the colour of wood without hiding the grain or texture. It is usually followed with a protective coating such as varnish.

Varnish is a clear finish that dries to a hard, durable finish.

PAINT COLOURS

Tone refers to a variation of a colour produced by mixing grey with the original colour.

Undertone refers to the subdued colour that can be seen through another main colour.

Pigment refers to the physical elements added to paint that creates its colour.

Tint is the material added to a base paint to achieve the final colour. Paint colours are produced using varying quantities of a number of tints.

Neutral colours are not bright or strong but may have undertones of other colours in them. Examples include white, beige and grey.

Primary colours are red, yellow and blue. These colours can be mixed together to create all other colours.

Secondary Colours are created by mixing two primary colours. They are purple, green and orange.

Tertiary Colours are colours produced by mixing a secondary colour with one of the primary colours used to make it.

Yellowing occurs when a paint or varnish ages over time. This usually occurs with oil-based finishes.

PAINTING TECHNIQUES

Bagging refers to a rough sand and cement finish applied to brick or blockwork.

Blistering describes the bubbles that form on a finished paint job, caused by moisture or dirt on the pre-painted surface or if paint has been applied before the previous coat is sufficiently dry.

Caulking is waterproofing gaps between building materials using a flexible filler.

Cutting in is achieved by using a brush to paint around the edges of a surface that requires a clearly defined line of paint but is too difficult to achieve with a roller.

Laying off refers to going over freshly applied paint with a brush or roller to ensure it has a uniform appearance. It’s important to ‘lay off’ a surface by brushing or rolling in the same direction.

Marbling is a painting technique designed to look like marble.

Marine finish is a hard-wearing finish that will protect against the effects of water and salt.

Masking is achieved by covering areas, that are not to be painted, with masking tape or paper.

Nap refers to the length of fibres on a paint roller. Short nap rollers are for gloss finishes; medium nap for low sheen and matt paints; and long nap for rough or textured surfaces.

Opacity refers to the covering power of a paint. A paint with high opacity will need less coats to cover over another darker colour.

Overspray refers to paint that has missed the intended surface and painted something else instead.

Paint pads are alternatives to brushes and rollers and used for smooth surfaces. Available in a range of sizes, some also come with guiding wheels for a smooth line when cutting in.

Re-coat time refers to the time it takes for a coat of paint to harden sufficiently to allow for additional coats.

Runs are the drips appearing in a finished paint job caused by trying to apply paint too thickly.

Sanding using sandpaper, is used before painting, and between coats, to ensure a smooth top coat. Glossy surfaces can also be sanded to ensure following coats adhere evenly.
