When put on top of Zinssner peel stop bubbles formed and needed scraping off. Is 123 actually required. Advised to “scrape off bubbled paint. Clean with meths, fill and reapply peel stop. No need for 123.”

Disappointed

Not as I had hoped, did not cover issues as described and very thin. Wouldn’t use again!

I used this on the inside of my log cabin to seal the wood before painting. The cabin is 17 years old and the wood inside had never been previously painted. Also the roof had leaked for the last few years but just been replaced so there were a lot of water stains and some dark patches on the wood. The paint worked great on the dark patches and water stains but needed about three coats to stop the tannins in the wood from bleeding through. I hadn’t expected this but read that it’s quite normal and to just apply more coats of paint/ sealer.
While no product is ever perfect, I can honestly say that I was pleased with how Zinsser Bulls Eye 123 Primer sealer paint in white covered everything.
I’m yet to try and see how it works on upvc but I’m sure it won’t let me down. It was definitely a good buy.

Product used to prime silk vinyl emulsion on ceiling that could not be rubbed down prior to painting with Matt vinyl emulsion. Applied to heavily textured artex ceiling so not easy (due to texturing) but covered well. Easy to clean up as water based product.

Excellent paint ,
I use this as a primer and undercoat,
Usually needs a couple of coats then leave a couple of weeks before top coat,
Needs minimal preparation to the wood ,

I have purchased this paint to cover my varnished interior door. I have sanded the door use satin wood paint to coat, still showing the varnish , purchased this pint hoping it will cover the varnish, I painted 3 times, and then painted the satin wood paint for finishing.
This paint is not as described on the tin, or maybe I am doing something wrong.

Used this to prime and undercoat some old fencing that's had all types of fence treatment applied over the last 10 years. Covered it easily.

Pricey but an excellent product for priming any surface

I am impressed with this product having used in the past. So much so that I bought some to take to my son in France (and also bought an additional can for me).

Used in France to paint lots of woodwork as a primer/undercoat. I also showed my son how well it would coat over dark colours and on metal and plastics, but left it for him to finish those jobs when he has the time.

Hopefully it does what it says on the tin, stain block and primes and undercoats for our finish cost(s). But not the best on MDF edges.
