hi guys this is Val from core conservation we're just back from Italy from a conservation and Plastering training and this video is about the application of our
00:00:16
aerogel lime plaster dutertanti original plaster which is an extremely performant thermal insulating line plaster which can be applied on virtually any surface
00:00:28
and provides excellent breathable lime thermal insulation in a very very narrow footprint in a very very thin layer thanks to the Aero gel content it's just
00:00:42
basically thrown on the walls is fairly sticky then with a large just worked and leveled to the desired thickness 10 millimeters can be applied in one
00:00:57
pass then once the first 10 millimeter is dry takes about half a day depending on ambient condition maybe a day then you can apply the second coat and
00:01:10
so on doesn't have to be super smooth once the plaster basically you reach the the desired thickness then just let it dry if you apply several quotes it's
00:01:23
advisable to apply a fiberglass mesh in the last layer or every 20 millimeters now use the surface how it looks like because the plaster is very very light
00:01:40
thanks to the high content of little gel so if the plaster left as it is when pressed with the fingers or even banged is going to leave indentations in the plaster
00:01:53
that's why it needs the protective finish which can be left as it is a bit gritty As Natural lime or meet completely smooth making lime surfaces very very smooth
00:02:07
with lime Patty is a Plastering trick we learned in Venice the Patty is applied uniformly throughout the surface worked into the surface
00:02:19
until we get a nice smooth finish using a large white throttle metal trowel the process may can be made faster and
00:02:39
large surfaces can be made nice and smooth this way the quality of the surface can be tested with the torch once it's dried if you leave it basically for about half an hour it dries very quickly
00:03:05
and you can see it reflects the light it's almost like a glass the smoothness of the surface is like gypsum or glass it's really really nice recapping
00:03:18
first the original plaster is applied in one pass 10 millimeters can be applied at once several layers can be applied on top of each other if desired although for larger thicknesses we have other thermal
00:03:32
plasters which basically are more suitable to build up several thick layers once the thermal plaster has dried we need to apply a finish a protective
00:03:45
finish we apply for this dedicated lime plaster and the surface can be made either root or smooth or it can be left naturally gritty like a normal lime plaster in
00:03:58
normal building hope you enjoyed it thank you for watching
