We have started Plastering!

Its been a long time coming, but its finally here!

We have started plastering!

We have done the first layer of plaster on some of the walls.  Our walls are anything but flat so it will take a couple of layers to get it looking…. rustic..

After a lot of research, a couple of courses and lots of umm’ing and ahh’ing we have decide to go with a base layer of lime and very fine gravel known locally as “cero”.

Benefits of Using Lime Instead of Cement

Our walls are made of a very porous sandstone (called “mares”) that acts like a sponge and sucks up water. If you cover this stone with a non breathable material (like cement)it will end up getting saturated, rotting and the result will be large parts of your plaster falling off.

Lime plaster is breathable, meaning that it lets vapour pass through it.  This allows your walls to regulate not only the amount of humidity in the actual wall itself, but also the level of humidity in the room. So, in theory we shouldn’t have the typical humidity problems that plague old houses on the island.

Another great benefit of lime is that its antibacterial and anti-fungal and so its a lot harder for mold and any other unwanted fungus’s and bacteria to grow in rooms that are plastered with it.

Lime is also thought to be more “eco” friendly as it takes less energy to make and emits less CO2 into the atmosphere than cement.  In the long run it actually absorbs more CO2 (from the atmosphere as it “carbonates”, which is the process which makes lime harden) than is used to make it.

Here are a couple more pics:

Its really nice to have some of the walls plastered as you can start to see glimpses of the house emerging from the barn.

If you are interested in learning how to plaster with lime and clay, Miquel Ramis does a 2 day course here on the island which is very good and cheap too!  He also speaks very good English for those of you with Spanish problems.

We saved a lot of money by going on that course as before it we were going to buy all of our plaster “ready made” and now we are making it ourselves at a fraction of the cost.
