What paint for inside greenhouse

Hi all just finished boarding and insulating the north wall of my small winter part of the greenhouse I had the boards given to me (1/2” non water proof osb) so looking to paint it to seal it but not sure what paint type (mold etc) and colour
Thanks for looking all

 

Can anyone help please

 

Gloss white.

 

Hi Notty.....I'm not sure what's required but I'll tag in @pete and @Scrungee and @martin-f because I reckon they'll know what's best. They'll prob be online sometime today

 

If it was me I would either use a PAINT type fence coating like garden shades or exterior gloss if you want a light colour to help seal it against the air moisture,if your not fussed about the colour black bitumen paint will seal it really well.

 

Thanks for all the responses my reasoning on colours was with it being the over winter part it will also be used to grow in the summer so a gloss white would reflect more light in the winter but the mat black (bitumen) would attract more heat in the winter but would the black be to hot in summer also thinking of mold resistance with it being damp and humid

 

I use Sadolin for my wooden greenhouse inside and out.
There is a choice of colours.......Sadolin Classic orSadolin Extra.

Sadolin

 

Never used OSB , but I would find something to seal the edges . That is where you are likely to get water blowing . I would coat with a cheap water based and thinned primer , the OSB will drink the first coat ! Then white water based topcoat(s).

 

Most informative thread ....learning lots here everyone

 

I was looking at this
Acrylic Roof Paint 20L | eBay
In light grey quit cheap water proof and should go straight on the osb
