    Hi all,

    Been asked to paint a large staircase white that's currently stained. Never had to go from one to the other before on a staircase, so after some opinions about what primer/undercoat to use.

    Have used Zinsser BIN before on a prepped stained surface but wasn't overly impressed as the gloss chipped back to the stained surface upon impact. Also, I find BIN a pain to use as it dries so fast, so don't really fancy using it on a complicated staircase.

    Old client or I'd've swerved the job, especially as it's 107 spindles, 15 newel posts and 12 handrails, so I'll probably be a bit nutty by the end of the week!!

    Tempted to make the quote V expensive instead, but as ever, any help appreciated :)

    as for a primer before i worked as self employed the company used aluminium wood primer on a stained wood that was to be painted white..never saw the stain again!
     
  4. I would use BIN for this but I would ignore the claims that no sanding or de-glossing is required. I would prep by using sanding pads wetted in a sugar soap solution, wash down, then prime with the BIN. I apply it with a mini emulsion roller, I can get loads of BIN on real FAST that way. Then apply Crown SOLO gloss or satin again, with a mini emulsion roller but laying off with a Purdy or similar. Used this method on hundreds of previously varnished stair spindles with great success. With handrails I would usually apply 2 two coats of quick dry primer undercoat over the BIN, sanding between coats to get a super slick finish.

    Thanks for the replies,

    GC, I'd never have considered that in a million years - like you say, the unexpected option!

    was it yourself who posted a comparison of different undercoats on here a while back? I seem to remember it made interesting reading but I can't remember which was the best product!

    Interesting stuff :) I would have plumped for Dulux Aluminium Wood Primer in this instance.

    Yeah BIN is a pain in the @ss on fiddly areas due to very short open time. I usually use a brush for the fiddly bits then for larger areas get a couple of coats on with a foam roller followed by a gentle rub down with Between Coats (or a pad on fiddly bits to avoid taking the BIN straight back off on the corners)

    :)
