I have been plastering for 25 years, from lathe and lime, float and set to skimming and k rend, I can do it all. Nothing is too big or complex, and I'm quite happy doing a little ceiling here and there. Shed loads of experience and plenty of passion. Have built plenty of extensions and new builds from scratch over the years with my team but happy on the trowel now. I have been plastering all of my adult life I am 40 years young. Thanks
