I prepped my front porch floor last year by scraping, sanding smooth as much as possible and then applying Valspar floor paint. As background, the porch is part of a 110 year old home and is covered with a roof but open on the sides. The paint lifted in one month! I contacted the representative who indicated that Pennsylvania does not allow the sale of oil-based paints which were, according to him, the best for such use. This isn't the first time I have had problems with paint lifting prematurely.
Since I can't buy oil-base paint here, has anyone a suggestion on some other paint which WILL stick? Epoxy-based.....?
Everything Mr. Paint said is dead-on - including, and especially the part about realistic expectations of paint performance on horizontal surfaces. As is in all paint apps, proper and necessary surface prep is paramount...and a high quality acrylic system should work well in your situation.
But after saying that, I gotta challenge your paint rep in his response to you. Pennsylvania's VOC & OTC regs absolutely does NOT prohibit the sale of alkyd/oil products, and there are many companies that continue to manufacture alkyds for use in strict markets, for re-sale to the homeowner (without an OEM exemption)...Some companies have simply decided to no longer offer alkyds 'cause it's just not worth the reformulation shuffle they must go through each time our well meaning legislators decide to lower VOC allowances - but there are still several manufacturers that recognize the demand and advantage of alkyds in specific apps, and can (and do) bring these viable products to market within the allowable VOC regs (including Pennsylvania)...
Also, on exterior wood floors, the disadvantages would actually outweigh the advantages of using an epoxy rather than an alkyd or acrylic...Talk to your local Independent Paint dealer for his/her advice and recommendations...
