How to stop stain coming through?

[Karenwh52]

I have used 2 coats of Zinster cover stain blocker on an old table I used a paint stripper and have sanded the wood back. After 2 coats of the stain blocker I can still see some stain coming through. Will the stain disappear once I have applied my 1 top coat of paint or do I need to do something else that

Hello @Karenwh52 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your paint project.

It appears that the stain is very strong and is bleeding right through the primer. I suggest applying another coat to stop the old paint or stain from bleeding through. This sometimes happens when you have a very strong stain painted over your timber surface. A third coat might be necessary to seal it properly.

Please keep us updated with your progress, we look forward to seeing your table ready for painting.

If you need further assistance, please let us know.

Hi Eric I took your advice and have painted another coat of primer on my table. This does not seem to have made much difference as the red stain is still showing through

i spoke to a lady who rejuvenates furniture for a living . It’s worth noting the since my table was made in Asia somewhere they tend to use kerosene to thin their paint and she has suggested that is why the stain keeps re appearing .I was going  to paint the table white but she suggested that even if the stain disappeared after painting it could reappear several months down the track and ruin my project. I have therefore gone with a black paint for the main part and intend to do the top a lighter brown or maybe just wax it

The person I spoke to suggested I would have been better not to strip and sand but to just use  primer over the original stain as the timber has already been sealed by using a varnish or some sort of shiny finish.
I will certainly try this on the project.

I now have my 1st coat of paint on Do I need to lightly sand between each coat or will sanding effect th3 primer

Hello @Karenwh52 

I'm sorry to hear that the stain still passed through the primer sealer. It's highly probable that there is a strong chemical such as kerosene that is bleeding through the primer. Your choice of using a black paint is a good idea as it will hide any stains that might come through. In regards to sanding, I suggest using 240grit and just lightly sanding the surface to remove its shine. Clean it off before you apply the next coat.
