Gloss enamel Alkyd was used to paint stair treads.Not done correctly. Stroke marks! How do I fix? ?

Sanding out will be a nightmare, should they be stripped via hot gun or chemical or can I topcoat with another product to smooth out?Gloss enamel Alkyd was used to paint stair treads.Not done correctly. Stroke marks! How do I fix? ?
Tuff call. First, if you decide to strip the problem paint job, I'd advise using a Heat Gun rather than chemical. A heat gun will do the job with much less mess and less time. Even so, the treads will have to be sanded before you can repaint; and you'll probably have to prime before top-coating.





I don't see why you couldn't go over the existing paint with another coat. Surfaces should be lightly sanded first to remove the ';gloss'; and be sure to use oil-based enamel. With stair treads having high traffic use, I'd use industrial grade, commercial grade, or exterior grade porch and floor enamel. It's more expensive, but definitely worth the additional dollars.Gloss enamel Alkyd was used to paint stair treads.Not done correctly. Stroke marks! How do I fix? ?
To add to the last post, you wouldn't have to sand off ALL the paint. Just enough to cut off the brush marks and get back to a smooth surface. Use a fairly fine paper (220 grit or finer) and a sanding block to have a smooth sanding surface, and have at it. It really wouldn't take too long to get down to a dead-flat base for the final coat. After that, use a good brush, and don't go over the same area again and again. Let the paint flow and level itself.
You may want to lightly sand the paint to knock down the high parts. The important thing to do when you repaint is to use a soft bristled (good, high quality) brush. The brush marks are usually a result of trying to apply too much paint at one time and from using a cheap, course, low quality brush. Try to compare the brushes to this. Which one slides across your skin better, silk (a good quality brush) or burlap (a cheap, disposable brush). I hope that helps.
unless you are spraying or rolling your treads you will never eliminate the brush marks but you can make them less noticeable by using a top quality brush as far as correcting the problem you have now try using a course wet and dry sand paper and wet sand the that is if your paint has fully cured
life_lov answer is right on - you may also want to use a primer - and if to are going to change the color have the paint dept. put that color pigment in the primer -
