Hot Limes in Building

This course presented by the SPAB in association with the National Trust, draws on recent research into hot limes to explore their use in building – mixes, techniques and applications.

  • Booking essential
  • Admission applies

This one-day course led by an expert tutor is ideal for anyone with basic knowledge of lime who wants to explore the use of hot mixes in more detail. Through a combination of illustrated talks, video and demonstrations, it will provide a practical insight into hot limes and their use.

After many years producing lime mortars by first slaking putty, then mixing with sand, it is now widely accepted that mortars were traditionally mixed ‘hot’. This means slaking the sand alongside the quicklime in a single operation.  

The day will be a mixture of illustrated talks and demonstrations, covering slaking methods, different mixing methods, application and aftercare. Nigel will also explain the essential properties of hot lime mortars and explore the reasons for their superior performance in terms of shrinkage, durability and frost resistance.  

This intermediate course is especially relevant for builders already working with lime and looking to extend their knowledge and use of hot mixes, and to specifiers wishing to develop or enhance their understanding of hot lime and its applications. It provides up to date information on our understanding of traditional mortars, as well as detailed practical instruction and is therefore essential for anyone working in the field. It assumes a little background knowledge of lime, and anyone completely new to the subject is recommended to attend the 'Introduction to Lime in Building’ course, taking place the day before.

What is Gift Aid?

Most of our places run the Gift Aid on Entry scheme at their admission points.

Under this scheme, if you're not a member you have the choice of two entry tickets:

  • Gift Aid Admission
  • Standard Admission

If the place runs Gift Aid on Entry, we'll offer you a clear choice between the Gift Aid Admission prices and the Standard Admission prices at the admission point. It's entirely up to you which ticket you choose.

Gift Aid Admission includes a 10 per cent or more voluntary donation. Gift Aid Admissions let us reclaim tax on the whole amount paid - an extra 25 per cent - potentially a very significant boost to our places' funds.

An extra £1 paid under the scheme can be worth over £3 to the National Trust as shown below:

  Gift Aid Standard
Amount paid by visitor £11.00 £10.00
Tax refund from Government* £2.75 £0.00
Total received by the National Trust £13.75 £10.00
