Over 80 years old... lots of old drywall damage and previous tenant destruction.
Lot of patching...and other flawed surfaces so I
textured over the walls with mud and stipling brush. Hides all the patching and repairs. I think I need to KILZ over it all to seal it before applying final coat of Enamel. Prior tenants were also smokers.
Business partner is lazy... he says no need for Kilz. I am wondering if liquid from paint will also cause the MUD/Texture to discolor and yellow slightly as I have seen it do when moisture hits it.
Advice? Suggestions? Know it is a bit more work, but less in the long run perhaps? Also cheaper to Kilz at $ 50.00 per 5 gallons than paint 2 coats at $ 85.00 per 5 gallons. Don't know if I need to KILZ at all however. HELP?
