Course Details

Are you looking to get started with lime rendering or plastering? Lime mortars and plasters were fundamental in the traditional construction of solid-walled buildings and today play an essential role in building conservation. As a traditional building skill growing in popularity, now is an excellent time to gain the knowledge and see the skills required to make a start.

This one-day course consists of two parts, theory and practical. Hosted by our own Phil Brown and Master Plasterer Sean Wheatley, we begin the day with an introduction to the theory behind lime, providing a solid foundation for understanding how lime works, its applications and the benefits it can provide for solid wall construction.

The second part of the day will include practical demonstrations and hands-on training, including guidance on background preparation, application and finishing, plus tips from Sean and Phil’s experience working with lime. There will be plenty of time for Q&A throughout the day, and open discussion is encouraged.

This course is ideal for contractors, building professionals, specifiers or homeowners and DIYers looking to get started with lime rendering and plastering. For a more general introduction to lime and its applications, see our Lime Training Day.

Most of our courses are designed to be inclusive and beneficial for a broad audience, including contractors, building professionals, specifiers or homeowners. Keep an eye on the course details for specific recommendations for each course.

No, you do not need to bring anything specific. All PPE, tools and materials are provided. However, we recommend wearing suitable clothing and footwear, including warmer layers for spring, autumn and winter courses.

Of course! You can purchase a course online, get in touch via email at or call us if you’d like to purchase a course on behalf of someone else.

The Premier Inn Bodmin (Launceston Rd, Bodmin PL31 2RW) and the Westberry Hotel & Restaurant (Rhind St, Bodmin PL31 2EL) are both nearby and practical options. If you want to experience some local history, we recommend the Bodmin Jail Hotel, a local landmark and historical site, a project we were proud to be a part of.

Working with lime or lime-based products can initially seem intimidating; however, your skill and confidence will grow with a solid understanding of how and why lime works, patience, and persistence.

Like any other skill, practice makes perfect. While we can provide a solid introduction to practical lime plastering and rendering techniques, refining those skills will take purposeful practice well beyond this initial course.
