Plastering soon...quartzscapes Tahoe blue. Should we just go with a white with the specks in it such as the Super Blue. I have heard that Adding dye such as blue to plaster causes problems. Has anyone experienced this and am I over analyzing? I know there will be mottling/variation with dye right? Also if your PH gets out of whack it will cause some problems for your plaster. But won't that cause problems for ALL plasters dyed or not??? PLease advise! If I'm going to change plaster colors I need to do it immediately. I don't want to make a costly mistake. PB said it's already ordered but I'm thinking it's been delayed before it can be delayed again. It's pouring down right now. Supposed to plaster tomorrow. Do not know that it can be done anyway! Thanks!
