Hello. I'm a newbie so pls go easy on me. I have recently been on one of these crash courses to learn plastering to do my home and am after your advice pls. I have started wit the smallest, box bedroom and have skimmed two walls both being approx. 9ft square. Now from a distance visually they look good but when you rub your hand over then you can feel the peaks and troughs, nothing substantial but they are there. Perhaps I'm being over critical as its my first DIY job after the course but I would like to erase these blemishes and in time get the perfect skim. What I m doing is two coats then finish with trowel, let go tacky then wet sponge using figure 8 and then allow to almost dry and then using spray bottle finish off removing any access and giving glass like finish. Pls don't bet me up by you guys that have been in the trade for years...I'm after advice....thank you..... somtam
