Rendering a wall

[steveo]

Have an external wall that half the render has fallen off. Have chipped off all the loose stuff ultimately be covered in plants. Never done this before so want to have a go.

What mix? Any tips?

You must be able to buy ready mix render somewhere

I think the mix is 4 parts course sand, 1 cement, 1 water.

Well I will obviously do that after my effort fails but I've never done it before so want to have a go.

Not sure on mix ratios, I've not rendered before. I'd mix up a little bit and practice a few times, by the time you get around to a second layer I reckon you'll have got the nack. I hadn't done repointing before so did a little bit to get the hang of it and then just went for it in a day and did the whole of our garden wall.

I guess with most jobs involving cement, it's about getting into a good rhythm. Mix smaller batches with a drill-mixer tool because it's quicker/easier to get to the right consistency.

It is if you spend your days in front of a computer.

Here goes!
Firstly make sure the existing render is stable! if when you tap it around bare area it's not solid,knock it off with a hammer until you can no longer knock off render easily!
Brush off dust/mould etc with wire brush.
mix up pva glue (wood glue,kids white glue) with water,(watery mix), brush on area!
As said mix 4 parts sharp sand to one part cement and plasticiser(you need very little of this look for febmix)
Plasticiser makes the cement more waterproof and workable.(this is where you may have seen the use of washing up liquid,but if you've got abit to do you might as well buy the proper stuff).
Mix up and trowel on! To level off find(or buy) a straight piece of timber that is longer than the patch you are filling if possible, Now keeping straight edge on original render slide until you have a flat surface between old and new.
Any excess new render as you work your way,take off straight edge clean with a trowel,put back in bucket and go again!
Like baking a cake the work is in the preperation!
Good Luck!

Did you leave enough room to get your fridge out?:hilarious:

Just for the record febmix has no waterproofing qualities and any waterproofer should go in the scratch coat(first coat) and none in the secound coat but well done Stevo.
