Painting new interior cavity walls of new shed

The_Mask

Hi guys hoping someone with experience can help me out. Just had a new cavity block shed built and I now want to paint the interior. Do I need to prime first then paint or can I paint weathershield directly onto the blocks. Any help or tips appreciated. I will be spending alot of time in the shed so I want to do a proper worthwhile job.thanks

Water down your first coat of weathershield, clean the wall well, get rid of any salts on the blockwork and paint. Thicker coat the second time, may or may not need a third coat depending on the coverage.

I just painted a cavity wall over the weekend, you can paint (well I did anyway) directly on to the blocks but water down the first coat. You're still looking at about 3 coats anyway.


edit: Happyman got in there just ahead of me.

No need to put weathershield inside your shed. Buy a 17.5 lit of white/magnolia Fleetwood extra plus. Thin out first coat and use a long pile roller.

Thanks for the replies folks. Today I scraped the excess blobs of cement and edge of blocks with a trowel to smoothen out the walls then used a hard bristled brush to remove as much dust as possible...might even fill any large holes if time permits. I have been advised by someone in the know to polybond the walls first then apply an interior or exterior paint of my choice, gonna go with an exterior paint as they seem to on sale everywhere.
