Acrylic paints can be used to paint wood for indoor or outdoor purposes and they are available in a vast range of colours and textures. These finishes are water based which means they dry fast but excess paint can also be easily removed with a damp cloth.
When buying acrylic paints for wood use there are different sorts depending on whether you will be using it on interior furniture or exterior furniture. For outdoor use the paint is generally more durable and has greater resistance to sun and weathering where as interior paint does not usually need this extra protection.
This type of finish is best applied to timber furniture by brush because it allows better and more consistent paint coverage and is very easy.
They need little to no maintenance compared with a wax or oil finishes because of how durable and resistant they are however outdoor furniture may start to peel or degrade over time depending on the quality of the paint and how harsh the conditions are.
Over time your furniture may need to be repainted especially outdoor furniture due to damage from weathering or general wear from being used. If so it is easier to remove old acrylics from wood then it is to remove old oil or timber stain but the same basic methods are used.
To remove an this type of finish you can either try scrapping it off if starting to peel or you can sand it off, the best method is usually to use a combination of power sanders and hand sanding. It is best to start with a coarse sandpaper to remove the bulk of the paint then move down to a finer grade.
After you remove the old paint make sure to sand the bare timber until smooth then remove all dirt and sawdust to achieve the best results. After the timber is completely sanded and clean you can reapply a new colour or change to a timber stain or oil.
