using the right primer for spray painting wood (pine)

[Jeff007]

Hi. I'm trying to get spray paint a new bansiter set that I've bought.

My questions are:
What type of primer (that is sprayable(gun ready) is needed to get a good base without the grain raising up, going furry and not allow the top coat to seap through.

What type of top coat (satin) should I use.

helpfull wonnabees please don't attempt to answer this question
many thanks !!

If the timber is raw, any paint you apply will lift the grain. That is what primer is intended for. This then allows the wood to be rubbed down and bind the surface together to stop it lifting the grain on sunsequent coats. If your having satin as a finish then there is no need for an undercoat. Any of the standard oilbased finishes or the waterbased ones can be sprayed if they are thinned sufficiently enough.

Oooh we'd never think of it. After all, we are just a bunch of hopeless nincompoops.

What you should really worry about is your own ability as you clearly don't know what you are doing.

If you want a very high quality finish then look at using acid catalyst spray. This is a two part paint that you mix, you decide the sheen level at the point of purchase.

eg

It is touch dry in a matter of minutes and the primer will NOT raise the grain.

On the down side it is pretty toxic and you should use a charcol filter mask.

You dont say which kind of sprayer you intend to use. if you go for A/C then I would suggest HVLP (either turbine or compressor).

In practice you can just spray the wood using the finish colour and forget about a primer.

It is very easy to work with and will atomise much better than standard water or oil based paints. it is more expensive though but IMHO the costs are out weighed by the advantages (speed of drying, ease of use, durability and non yellowing).

If you do decide to go water based or oil based then I strongly recommend the following.

1. Floetrol- an additive for water based paints.
2. Owatrol- an additive for oil based paints.

These will help you acheive the correct viscosity with out relying on too much water or white spirits.

Good luck
