I want to paint metal.
What do you need for this?
Alkyd enamel is the best choice for painting metal surfaces - compared to acrylic enamel it has a higher adhesion to metals. But first you need to prepare the surface. If there is rust on the metal, clean it with sandpaper, treat it with a rust converter, then wash it off with water, wipe the surface dry, degrease and paint. Many alkyd enamels can be applied to metal without primer, but using a primer will definitely improve adhesion and protection properties. It is not necessary to varnish alkyd enamels to give strength and gloss, as they are strong enough by themselves to form a glossy surface.
Are the cans reusable?
The aerosol can of coating material can be used many times during its shelf life. To prevent the spray head from becoming clogged at the end of use, turn the can upside down and spray until no more product is coming in. Stop spraying when only gas comes out of the sprayer.
I want to paint the plastic.
What do you need for this?
The first thing to note is that not all plastics can be painted. Polyethylene, polypropylene, Teflon and Silicone are not paintable. Before painting, the plastic must be cleaned and degreased. Matting the plastic with sandpaper is not necessary - it will only spoil the surface. It is better to use acrylic enamel for painting the plastic - it is more elastic and has better adhesion to the plastic. It is possible to apply acrylic enamel on plastic without primer, but it is better to apply one layer of adhesion activator beforehand. If you want to paint the plastic with alkyd enamel, the use of an adhesion activator as a primer is mandatory.
I want to paint wood.
What do I need for this?
The wood can be painted with both acrylic and alkyd enamels.
Acrylic enamels can be applied with or without a primer. The reason is that acrylic enamel is a thin layer, and without the primer the wood texture will show through the enamel layer, creating an additional decorative effect. If an even, smooth surface is desired, the use of a primer is mandatory.
Alkyd enamels should only be applied to wood with a primer - otherwise you will not get a smooth glossy surface. The general rule when painting wooden surfaces: after the first coat of any primer, enamel or varnish, the pile rises and the surface becomes rough. Therefore, the first coat should be made thin, let it dry and sand with fine sandpaper.
Then you can apply subsequent coats - so the coating will be smooth. Detailed instructions for selecting wood staining materials.
