Reinforced osb subfloor. Primed osb with manufacturer suggested primer. attached metal lath, stapled every 3 inches. Mixed (too much water I’m thinking) slc and poured. everything went well, minus not having area as well dammed up as I thought. 9 days have gone by, and I’m now seeing a hairline crack. I can’t feel it when running finger, but it’s there. This is a powder room, should not see much water action. planning to tile this weekend, do I need to stop and pull the slc?
