My brotherinlaw made a fish tank stand and hood for us the cabinet doors and hood panels had to be made with MDF so as not to warp, I was going to prime it but was told a few coats of paint was all that was needed WRONG, after having quite a few coats of paint it looks streaky and horrid. The fish tank and stand is 6ft so its a lot of messy paint work to look at lol :lol:
My question is can i use a primer on it on top of the paint thats already on? would that do the trick?
In all honesty it is probably best to rub it all down and start again, using the correct primer/sealer at the base stage and then a top coat once primer is dried. We do have a project page that walks you through the process here: https://www.diydoctor.org.uk/projects/mdf.htm
