Linseed paint helped protect wood and iron for many hundreds of years. Since the advent of petrochemical paints, however, the industry has largely forgotten the value of traditional alternatives. This book provides an insight into the benefits of linseed paint for architects, professional decorators, restoration professionals and DIY enthusiasts alike. It describes in detail the unique role linseed paint plays in the preservation of historic buildings, including: What linseed paint is, what the ingredients are and how it is made, the benefits of linseed paint and how it functions on a molecular level, how linseed paint can play a pivotal role in reducing microplastics and making the building and restoration industries more sustainable and detailed step-by-step instructions for applying linseed paint to a variety of surfaces. AUTHOR: Michiel Brouns has worked in historic building preservation for twenty years, and established the linseed paint company Brouns & Co. in 2011. He has worked on high-profile restoration projects including Woburn Abbey, Chatsworth House and Windsor Castle. He is widely regarded as one of the few experts in linseed paint, and he delivers presentations to architects across the UK and USA, approved by RIBA, AIA, ICAA and ACBA. 140 illustrations
