Hi,
Been given the go ahead on a rendering job. The extension is 7m long x 3m wide x 2.4 high. I have been asked to render the outside and inside of the extension. The outside of the extension has to be pebbledashed. After the inside is rendered I have to skim the walls also. Inside the extension where the old exterior wall was (back of the house covered by the extension) has old pebbledash slightly bigger than your normal spar and is painted. They want me to smooth over and skim. Maybe I could float and set it or maybe I need to use sand and cement as it may have moisture in it as it was exposed all its life,
The outside of the extension is common bricks and inside is thermalites. This is the biggest job I have been given on my own. Just a couple of questions as guidance...
1. How will I treat the walls? As the bricks and blocks are both high suction will I just hose down and render? or will I treat the internal blockwork?
2. I was thinking of 4-1 on the external brickwork and 5-1-1 on the top but what about the dashing?
3. As the Therms are internal, can I just do the normal 5-1 then 6-1-1?
4. Somebody said apply the therms with 1 sand/1 cement/1 pva and throw on leave to set then render?
5. Could Hardwall be used on the therms (i know its exterior) but the bricks will be rendered?
6. Im sure as the therms are internal is it the normal 2 coat work?
lastly the interior dashed wall, whats the best way to deal with it?
A lot of questions I know, but any help would be appreciated
Thanks
