Sealing a taped and filled finish prior to mist coat

Anonymous user 28/02/2024 - 2.54 PM

I believe that it is recommended to seal a newly taped finish in order to prevent future damage to the plasterboard when removing wallpaper at a later date. Should I seal before or after mist coating? Can anyone advise on a cheaper alternative to using a proprietary sealer..pva for example, mixed with the mist coat? Also, any tips on using paint to achieve a perfectly flat finish after taping as I'm still not convinced that the filled joints won't show as bumps and hollows..I need a top spec finish so please advise on the best application and emulsion to complete the look. Thankyou, Ruth Thanks LickofPaint. You came in a bit late by which time I'd already mixed my 'sealant' but as it happens I used exactly the same formula as you recommended.(woman's intuition?!) Have now nearly completed 250 sq/m of taping & filling, sealed, mist coated and top coated and my ceilings are as flat as witches tit..(husbands simile!) Thanks again, Ruth.
