when repainting old gloss paint, is it necessary to remove ALL the gloss I believe the paint is latex water base - but I'm not positive.

Will TSP alone take off enough of the gloss without sanding?

Hi Carol, welcome. That's a tough call. TSP is supposed to etch the surface/dull the gloss, but as to whether it is sufficient to create a bondable surface? Personally, I would at least scuff sand (light) the surface, then use the TSP, to be on the safe side. It's not too late yet, but after the paint is on, it is.
