In this video NCPTT's Sarah Jackson discusses the application and preparation of lime wash.

Limewash has long been used world-wide as a surface finish on the interior and exterior of buildings, homes, and other structures. Limewash is a mixture of slake lime and water with or without additional additives.

The National Park Service's National Center for Preservation Technology and Training protects America's historic legacy by equipping professionals in the field of preservation with progressive technology-based research and training. Since its founding in 1994, NCPTT has awarded over $7 million in grants for research that fulfills its mission of advancing the use of science and technology in the fields of archeology, architecture, landscape architecture and materials conservation.

    This is very helpful and the speed of delivery is just right (not too quick - at least for a native speaker). Thank you. xx

    When I slake my quicklime I rarely ever screed or sieve the tiny lumps. Especially on a exterior limewash or even a traditional lime render for that matter. Definitely do it for interior work though. Hotmixed limewash I believe is the best as it sucks moisture out of the wall as soon as it is applied. Beautiful stuff to work with when dealing with a damp traditional fieldstone basement. As for brick i always water down the wash, use it still hot after sieved through a food strainer. If its thin enough ill apply it straight to a dry plaster wall. If its a stone wall I always apply hot and thick with sand mixed so as to dig deep into any voids. Limewashing brick i always soak the brick first for a few minutes. The longer the better. Thin for the win with aged lime putty. Thicker with a hotmixed limewash.

    I noticed that some of the buildings that you worked on needed repointing of the brick walls before lime washing.

    Great video, thanks. It would be better if the narrator talks little slower :)

    you can make it thicker than in this video to reduce coats. this will take a longer time. with a perfect lime wash you should only need 2-3 coats not 5. this is time consuming and unnesesary.
