NOTE: The sound quality in the video
is poor in places but it's worth listening to carefully. There are
lots of valuable tips to glean from Ryan; a widely recognised
expert in tadelakt plasters.
Tadelakt is a lime plaster treated with olive soap and polished.
The lime plaster is applied in several thin layers, smoothed with a
trowel and then burnished with hard
tadelakt stone using an olive oil soap. The soap and lime
react chemically making a waterproof and durable surface. The
burnishing creates a beautiful glossy finish that is beautiful to
touch. The tadelakt takes 28 days to fully cure. Natural waxes can
then be applied and buffed to create additional protection.
Tadelakt is built up in several layers of plaster being applied
and smoothed first with a sponge and then with trowels. Finally
the soap is applied and polished with a stone. In the video above
Ryan teaches students how to apply Tadelakt.
