IS IT OK TO USE OIL BASED GLOSS ON A WATER BASED UNDERCOAT?

Yes, as long as the undercoat has fully dried.IS IT OK TO USE OIL BASED GLOSS ON A WATER BASED UNDERCOAT?
hi susan





yes you can do this and you should have no problems providing your substrate is prepped properly. personally, if it is raw wood i would apply 1 - 2 coats of an alkyd primer under coater then i would apply 1 - 2 coats of an alkyd semi gloss or eggshell. if you are painting trim it will come out like glass. if the paint starts to set up too fast you can add a product made by flood called penetrol it slows down the drying process and if your wood is raw it will help the primer to penetrate into the wood better. if you use a water based primer it will cause the wood fibres to raise and that means alot of sanding. if you want to speed up the drying process then get some japan driers. they are present in the alkyd paint from the factory but this will help it dry faster and gives it a tougher finish.IS IT OK TO USE OIL BASED GLOSS ON A WATER BASED UNDERCOAT?
Hi Susan,


A water based primer will be acrylic, which is perfectly fine for use with oil based paints. Are you using this on bare wood? If so, sand the wood, apply the first coat, let dry properly, lightly sand again and apply a second coat. This is only to give a better finish but isn't essential. Still better to do it though
yes it is fine ..internally ..but don't do it outside !as a builder i come across this al the time ...the paint can peel off completely leaving only bare wood ...i remember when acrylic primer first came out ..the decorators loved it ..it saved them time ...less than 20 years later ..all the windows and soffitts etc are being replaced !!
No.........you are backwards...........should be water base on oil primer, not oil on water.........you will have a bonding problem.......better to go water on water now. Sorry, I know that's just what you wanted to hear. Have a lovely Holiday........bye.
I have just done this. The water based undercoat is acrylic so is compatible with the gloss as long as it is properly dry. Follow the instructions on the can
Not a good idea. Oil-based paint needs more than a coat of latex in order to stick to the wall. Use a water-based gloss paint.
yes its perfectly ok


just not the other way round


make sure it dry between coat and give a light sanding inbetween coats to give a better finish
No. Oil based paint is stiffer than water based paint and will crack over time.
yes it is fine, my husband has done this before.
