Knowing when to Use Primer Spray Paint

When DIY enthusiasts are painting their homes, primer spray paint is rarely considered as a first choice. Normally, the first choice is the type of primer that comes in a tin and requires a brush for application. It is not always to know when to use spray cans in the home. Once you do, it will help you decide on other factors.

1 – Indoors

One quite debatable area to employ spray paint is indoors. Spray primer or paint needs a large amount of ventilation as it is unsafe to use in enclosed spaces. Think very carefully about the conditions of the space you are going to be painting in. If you intend to use a spray primer anywhere inside your home, think about fresh air, ventilation and the size of the room you will be working in. Make sure you have plenty of ventilation to accommodate the size of room you work in.

2 – The Last Coat

Primer paint is normally the protective layer of undercoat which is painted on to a bare surface. It is not usually applied to items which already have paint on them. Because of this, it is important to establish when to use primer paint and whether you actually need to use it. Is the surface you are considering spraying already coated with a previous layer of paint? Is it bare wood, tile or drywall? If it is already coated with paint, what sort of paint is it?

3 – Sealing

Do you need to spray the primer in order to seal an area? If so, you can quite easily use spray primer to seal a wall or other area in your home as a protective sealant against water stains or damage. Primer reacts to water damage and works in a different way to paint. If you are repairing a water-damaged area in your bathroom or kitchen, priming the area is a strong defense for the surface. Remember to make sure the room is wellventilated first.

4 – Surfaces and Materials

Not all surfaces are suited to being painted or primed. Plastic, for example, is not always suitable for any priming, whether it be spray or otherwise.  Plastic is non-porous and is manufactured as a water resistant material for use in piping or plumbing among many other uses. Decide whether the plastic surface you intend to paint will actually accept it before you start.

Styrofoam is unsuitable for most spray paint. Primers and paints can actually destroy the styrofoam surface. In most cases, paints and primers that are specifically designed for using on plastics are actually oil-based. The oils can cause damage to the plastic and can ruin it by warping or twisting soalways make sure the material you choose is for the right type of plastic.

Primers have a propellant, so check that it will not damage the surface before you spray it.  If you wish to paint a plastic surface and are unsure about compatibility, make a small test area first to be make sure it will not be damaged.
