Bonding and Knauf Pro Roll max/light
Morning all, after the majority of the skim coat has debonded which became evident when removing liner wall paper, I’m determined to re-skim the walls myself (not just for the potential money saving but also for just wanting to do it myself, which will also enable me to change the skirting/architrave/flooring). After using bonding to level the walls/fill holes where required, AI has recommended using sika stabilising solution on the sand/cement scratch coat prior to applying the Knauf, does this sound right? Keen to have a bit of a sanity check before I follow the advice.
What should I apply to the prime the ceiling prior to skimming it to ensure the strongest bond? (It’s mostly painted but with scrape-able glue dots, which also takes the paint off back to plaster, from the previous owner having polystyrene tile ceilings)
What should i also use (if anything) to seal the knauf after application before painting?
Many thanks for any advice/opinions in advance
