finishing plywood lining.

[Pulpo]

Greetings

I have or should say in the process of lining my shed with plywood 7mm.

I would like to spray it with say linseed oil or lacquer of sorts [100m2].

I really have little idea of what I'm after other than saying I'm not trying to stain it darker nor do I like the idea of just raw timber.

I get the feeling polyurethane would be best, I'm trying to protect the timber, I guess.

Any thoughts ideas or views would be appreciated.

Thanks

I would think that anything oil based will darken the ply and whilst the use of acrylic varnishes will lessen the effect of darkening the downside with those is that being water based you will get grain raise which in some plys can be a nuisance so you would have to seal first.The process either way would be very time consuming.

The effect of a shop lined with natural ply might be a bit sombre and I would suggest that a lot of the light could be absorbed by the ply "au natural".
Have you considerted simply primer,undercoat,and white emulsion which would be bright, easy to do, and very easy to freshen up or change whenever you chose.

Beejay, for a change I agree with you.


That is why I paint my workshop white.

Yup, off white with orange trim.

I lined my last office with good old el-cheapo C-D radiata ply, then gave it a coat of "liming" stain, (which I think I made myself by watering down some white undercoat and wiping it off almost immediately, but you can buy the proper stuff if you wish), give it a VERY light sanding after that, and one coat of clear anything (I used flat) to stop the dust getting into the pores of the timber.

End result is a ply wall that has a slightly white tinge, won't go dark, and keeps clean.

If you want a good finish, sand it lightly after the first clear coat NOT the white one, and give it a second coat of clear.

Cheers,

I think Bitingmidge it giving good advice. I finished radiata pine board panelling in a rumpus room with what I think was called "Liming White" and then coated with satin polyurethane. Radiata pine has the tendency to "yellow" or darken with the effects of ultra violet light over time. My panelling has not altered colour since it was fitted over 20 years ago.

Linseed oil will go black in time. Stick to a light colour paint, the glossier the easier to clean.
