Message: [QUOTE="ochster, post: 239501, member: 17624"] I have some cloudy, dark blotches, around about 1/3 of the perimeter of my shop. It has hydronic floor heat and is kept near 70deg., but these don't appear to be going away. I wan't to put a catylized expoxy coating on, but am waiting to make sure adhesion will be good. It is a 5"monolithic slab with 10hx16w incorporated footings, 6mil plastic underlay, poured two months ago. Any insight or sugestions? [/QUOTE]
