Painting All Dark Stained Wood in Home To White - Help!

Anonymous user 09/03/2024 - 3.28 PM

All the wood in our home - stairs, bannister, doors & frames, skirting, window frames, mantelpieces, handrails, architrave etc is stained dark cherry brown with a semi-shiny finish. We wish to change it all to Satinwood White using a Water Based paint as an oil paint would yellow quickly in our home. Much of it has been sanded down to bare - on these areas, I presume 2 coats of regular undercoat & then top coat is correct? Do modern water based undercoats have a primer built in? However, many areas & all hardwood doors still remain in the Dark Stained Colour which has been sanded with 80 Grit sandpaper. Told to use Zinsser Bin to cover the dark colour but with so much to cover, this would be extremely costly. I have seen YouTube Videos where Painters use the cheaper Zinsser 123 instead & some use Zinsser 123 Plus but this prices the same as the costly BIN. One paint brand (Isomat) said that with quality Water Based paints like their Isolac Aqua 2 coats of a quality undercoat plus a top coat will fully cover the dark colour without any bleeding through - is this correct? Their paint however, too is extremely costly! Please advise on the best/most cost effective way to paint the sanded dark stained areas as even with the cheapest Zinsser 123, we would need so much that it would be very costly for us & then more costs for the undercoats! If there is a way to simply twice undercoat these darker sanded areas & then top coat with regular good quality paints without using these costly sealers & still get good results, please kindly let me know! If not, should these remaining areas then also be sanded bare for best results then?
