Zinseer Bin balls up!

samtastic73 · 22 Apr 2020

Hello,

I'm an idiot. Didn't read the tin properly. I've coated my varnished front door and frame in Zinseer Bin trying to save having to rub down. Realised before I did the window frames.

Have I got any options or is it just sand down and start again?

Shoot me now

thanks

What were you trying to do (don't tell me "paint them")? And is it the outside of your outside door that you have coated with zinsser bin?

samtastic73 · 23 Apr 2020

Yes to the outside. I was trying to not have to sand down the varnish and cut corners. I'd read how the Zinsser can prime anything. Didn't (annoyingly) pick on the 'spot external'. So the external front door and frame have been painted in it. It went on great and dried quick but I now gather shellac-based paint dries too hard for external use so will likely cause the top coats to crack.

Pretty much decided to take it on the chin, sand it (and the varnish) down with a sander and sanding block and start again with an undercoat and two coats of gloss.

is what it is I guess. Live and learn!

Yup. BIN is only for spot priming (for knots really) on the outside. Try removing it with wet and dry, 120 grade to start with and 180 to finish perhaps and use a block for the flat surfaces. If you have methylated spirit try washing it down with meths and a scrubbing pad, it may or may not remove it.

The door and other surfaces especially if you sand them a bit heavy handed are likely to leak colour. You should use an adhesion promoting primer which is also a stain blocker, e.g. 2 coats of zinsser Bulls Eye 123 Plus, and also check zinsser for their solvent based stuff too if you are going down the solvent based route of paints.

Thanks Mate.

Do I need two coats of primer, then undercoat and gloss?

samtastic73 · 23 Apr 2020

Will these zinsser bullseye work as a primer over sanded/keyed varnish?

OchAye · 23 Apr 2020

Bulls Eye 123 is a high adhesion primer (will stick to difficult surfaces). Bulls Eye 123 Plus is the same primer but also a stain blocker. Two things: (a) use the Plus version which costs more money but will work better as a blocker; (b) when you apply the first coat if the colour of the previous varnish bleeds you will know, it will come through the paint, if colour bleeds apply 2 coats otherwise you would normally only need one.

You do not want to start undercoating and top coating to find that you still have colour leaking through. Watch out not to try test scratching the primer, it takes a week or longer to cure fully.

Here is 123 Plus https://www.zinsseruk.com/product/bulls-eye-1-2-3-plus/ and read the data sheet for precise instructions. There are other products but this is something you may be able to get on-line during the lockdown.

BTW, I am a DIYer.

It might be worthwhile dropping Zinsser an email and see what they say. I have only ever used it as a spot primer outdoors but have never quite understood why it should only be used as a spot primer. I don't see why the "hardness" would be an issue. Exterior grade 2K paints are much harder than shellac paints and some shellac paints are fine to use outdoors, eg Rustoleum Pegaprim Isofix
