I textured LR & DR after removing square tiles. drywall was yellowed after 25 years under tile. I taped & mudded then primed with drywall primer/sealer. now yellow is bleeding thru texture. Plus I messed up trying a knock down. I used nylon loop roller to apply then messed up a few spots with the knock down made it worse trying to touch up. Can I retexture, either using diff. roller or spraying on...?
Thanks for your help...Tom C
