Defo the go to product followed closely by peel stop
Relatively new convert to the Toupret range fine filler the MUTZ Nutz for those dings left by others all over really useful and an easy 180 rub off
Tool station always great value and yet to meet anyone not nice in more than a few branches

the product is brilliant, does what it says. purchased it to cover some water leak damage and grease stains on ceiling at my rental property. Bit expensive, but does the job. For grease spots i gave 2 coats but water spots just 1 coat was enough.

I bought this as have to do a lot of touching up after water leaks. Problem is this doesn't cover even a slight hint of a brown water stain. An older decorator told me not to waste my money and just buy oil based white undercoat. How right he is.

Excellent coverage. Used on a varnished door ready for change to painted surface. Very little preparation required and required just 2 coats plus top coat painting. Very impressed and will be my go to primer/undercoat.

GerryBritton Verified Purchase

Zinsser undercoat is the best one around , you pay a bit more for it but usually one coat is enough even on MDF which is difficult to seal before putting top coat on , this one is waterbased so brush cleaning is easy as well

I don’t use anything else

This is a really good primer. I must’ve used close to 30L over the years.

Applies well and painless to clean up.

Worth paying extra for a good product.

Having previously used Zinsser BIN paint, I found the fumes unbearable even when used outdoors. When somebody told me about Bulls Eye 123, I gave it a try and now like the lack of strong fumes and water based cleaning of my brush. So much easier to use.

The best primer I have ever used.

Easy to use, dries flat whilst still showing the underlying wood grain. I like the idea that it does three jobs, which does save messing about with knotting, etc.
