Painting lots of wood

[Charlotte]

I'm currently painting my kitchen which has t&g and plywood walls (it's a boat). At the moment I've applied one coat of Ronseal primer/undercoat/knotting. The grain on the ply is still quite visible...is there anything that I can apply at this stage to fill it?

Thanks

Charly

you could apply an oil based primer called zinnser coverstain then wait a day knock it back with 180 grit then re-apply another coat then you should havbe a brillant base for either a water based or oil based top coat sytem
