HELP! Please!
Long story short I regretfully plasterboard my living room, jointing compound in the seems of the tapered edges and corners…
It’s starting to look good and we’re getting to a position of wanting to paint…
My stepdad is old school and said PVA, but EVERYONE online says don’t do it…
We’re not skimming the walls and are hoping to paint over the boards direct… we have put a lot of work in for the joints to be perfect.
I’ve read up on Zinsser Gardz which is the most suggested option but on the other hand I have read absolute horror stories.
Can someone experienced give me an idiots guide of how I go from a dusty plasterboard/jointing compound to having the walls painted.
Any help and advice would be much appreciated,
Sincerely a first time reno couple wanting to cry on the daily🥲

The firm i worked for, any tape & jointed plasterboard walls I built just painted with emulsion, first coat diluted roughly 5 - 10% water not measured chucked in a paint bucket & mixed by hand. Worked there 20 years nevef had any come backs ever!

I just did a partition wall and taped and jointed it, just couldn`t be bothered to skim it
I was in the same boat not sure what to do, mist coat, pva etc. I did use the zinsser Gardz and it was a good solution.
A couple of notes, it is thin like water and will drip off the roller so go careful, it soaks in fast ( which is the point I guess ). Make sure you check for drips thoroughly because any drips will form hard little lumps when dry and are a pig to get off without tearing the paper and hard to sand. Do not let drips or runs dry.
Otherwise it does the job, evening out the absorption of the paint where the paper / filler is and paint goes on top nicely.

I'll just add that Gardz is also designed for fixing ripped plasterboard paper. So if you do damage it you can just Gardz back over it again 😅.
I use Gardz all the time, most often for taping and jointing. Never had a problem. Maybe those that say it doesn't work just never read the instructions 🤔

I did my garden room as you have done and just emulsioned it and it is fine. I believe people in the US don’t skim their walls.

Don’t PVA it, emulsion will not bond correctly to it. Use something like Zinsser Drywall 2 in 1, do two coats and then paint away with your chosen emulsion. I’ve done this in three rooms with a good result.

I've just done a room with Zinsser Gardz onto bare plasterboard, joins done with Gyproc jointing compound. Couldn't be more pleased, better finish than most skimmed walls. The finish you get with the Gardz is almost like a semi-matt varnish. You need a good quality emulsion and try not to over roll. And definately don't thin the first coat.

In my experience, taping seaming and painting (not skimming/plastering) is more for commercial/office spaces. Usually studs made from tin. I have always thought it was due to cost and speed but less durable. Plastering gives a hard shell and is more durable better in a domestic situation. You don't PVA bare plastboad either way.

With office space you need to return the space to it’s original state when giving up the lease - tin and board is easy to rip out 😁

Sand the filler, hoover the walls. Plasterboard primer paint, then paint with your choice of paint.
