bankruatsteve Posted August 1, 2013 Share Posted August 1, 2013 We have a little project putting in a pantry in the outside cooking area. The render/plaster just completed yesterday and my humidity thingy is showing 80%. Which it has for days on end now. When I did our house, I waited 2-3 months for the dry season to start painting. But, now I'm ready to go whenever it's time. So, cement gurus: when can I attack? Link to comment Share on other sites More sharing options...
bbradsby Posted August 2, 2013 Share Posted August 2, 2013 in high humidity, the cement plaster/render is happy as a clam. seven days is advised for wet curing - kept out of direct sun and wet as much as possible. This wet curing minimizes shrinkage cracking. Prior to painting, you want the plaster/render to be dry. I'd wait a month in the wet season, and several weeks in dry season, because you dont want to paint over wet cement due to risk of paint film blistering. 1 Link to comment Share on other sites More sharing options...
bankruatsteve Posted August 2, 2013 Author Share Posted August 2, 2013 Thanks. I would like to put in shelving strips/support and have everything ready to go for the eventual painting. Do you think I can drill holes for the plastic anchors for that after, what? a couple weeks? This f_ing humidity saps me so much, breaking it down to micro daily projects isn't all that bad.

bbradsby Posted August 15, 2013 Share Posted August 15, 2013 Sorry, just saw this... you can drill it in a week after render application. The true strength for anchors will be in the substrate, not the render. Link to comment Share on other sites More sharing options...
