Zinsser B-I-N White Matt Primer Sealer 1L

I bought this after doing a lot of research as I wanted a primer that would cover my mahogany stained staircase. It's very watery and required about 3 coats just to cover. And I think it could have done with another before I finished with a top coat. Hopefully, it's properties will mean that it was worth it for stopping any bleed through.

I bought this a month ago to undercoat an old wooden cupboard. It provides an excellent base for the top coat of furniture paint, but you have to work it quickly as it dries fast. I suggest two thin coats with sanding in between to get a smooth finish.

I bought this product following the reviews posted here and was not disappointed. I was looking to cover knots in bare wood, stains from spilt materials on a window sill and watermarks on a skirting board from a water escape without the need for multiple products. Two coats of this product along with 2 finish coats sealed all with no remaining trace of the issues. I did find the product to be thinner than I was expecting but was forewarned by other reviews here. It also dries incredibly fast so my advice would be to plan properly and work quickly! Other than that I couldn't be happier with it and would definitely buy again.

I bought a cheaper spray version which did nothing for our brown water stained ceiling. This did the job easily in 2 coats. Easy to use.

Bought this on recommendation from the fitter of our internal doors. Once it's stirred up it goes on really easily. By the time I painted from the top of the door to the bottom I could apply another coat for good coverage. Making sure the knots were well covered. It matches the pre-painted doors as well. So, a little sanding to smooth out the 'hair's in the wood and one final coat - Job done! Excellent product.
