Tracy D'arth Posted March 8, 2022 Report Share Posted March 8, 2022 A neighbour boater has an old boat with lots of stains inside from old leaks, bad painting jobs, red wine splashes ( hopefully its not blood! ) and general old muckiness. The wall panels are bare and seem to have never been varnished. Some of the woodwork is painted black and brown. Some is MDF. She is wanting to paint the inside white. As the wood needs priming is this the right paint to use and has anyone any experience with it? Zinsser Cover Stain Primer Paint White 2.5L Does it really stop the stains bleeding through? Will it cover dark paint? A top coat of white satin paint afterwards? Link to comment Share on other sites More sharing options...
David Mack Posted March 8, 2022 Report Share Posted March 8, 2022 I used Zinsser B-I-N primer to cover stains on a chimney breast caused by a leaking roof / flashing round the chimney. I was impressed. Flashing repaired, but no time to allow the wall to dry out. Two coats of Zinsser B-I-N followed by a couple of coats of emulsion paint and 18 months later there is no sign of the stain coming through again. Brushes need to be cleaned in meths or Zinsser brush cleaner/restorer. Link to comment Share on other sites More sharing options...
Nightwatch Posted March 8, 2022 Report Share Posted March 8, 2022 We are presently thinking of painting the varnished lower bulkheads. I have been seriously anticipating using Zinsser. It’s not cheap but if it works it’s well worth it. As the OP asks, any comment from past users. Link to comment Share on other sites More sharing options...
cuthound Posted March 8, 2022 Report Share Posted March 8, 2022 I've used Zinsser Stain Cover to successfully cover water stains on a ceiling in a house. Link to comment Share on other sites More sharing options...
Rebotco Posted March 8, 2022 Report Share Posted March 8, 2022 Yes Zinsser Cover Stain is the bees knees for that sort of job. It can be used on MDF as well as timber as a stain blocker and a base sealing coat. It does have a high volatile content though, so be careful on a boat to ensure lots of ventilation, as you don't want a hull full of flammable fumes.

Onewheeler Posted March 10, 2022 Report Share Posted March 10, 2022 Zinnser paints are generally very good. I've used them in the house on a wall prone to damp and on the gunwhales (the latter water based black paint but dead easy to touch up if damaged, and it seems to last).

Tracy D'arth Posted March 10, 2022 Author Report Share Posted March 10, 2022 Thanks for all the replies. Wow, its expensive stuff though. Link to comment Share on other sites More sharing options...
adrianh Posted March 13, 2022 Report Share Posted March 13, 2022 The cover stain (my prefered) is slow drying but seems to cover well. I have found that you need more than one coat on some stains allowing at least a day between. The BIN version is very thin to use with high solvent levels also. The zinser paints are very good also for the top coats. Look at screfix re prices Link to comment Share on other sites More sharing options...
Peugeot 106 Posted March 13, 2022 Report Share Posted March 13, 2022 I’ve used the Zinsser BIN + Zinsser Perma White on a damp (and mouldy) bathroom wall recently and it seems very good. It’s over a month since I did it and there is no sign of mould bleed through though it was previously painted plaster not wood. The Perma White is wet scrubbable. With paint I suspect you get what you pay for and the Zinsser products (and product support from the technical department)are very good. They publish a small red guide which I find helpful too Link to comment Share on other sites More sharing options...
Peanut Posted March 13, 2022 Report Share Posted March 13, 2022 Zinsser is what they used to paint smoky old pubs with to prevent all that tobacco tar bleeding through. Link to comment Share on other sites More sharing options...
