Traditional || Coloured Renders || Rendering questions ?

Traditional Render
Usually a 2 coat sand and cement mix, with other elements added,
such as waterproofers or other chemicals to make the mix plyable and protect against weather.
Usually mixed with a standard cement mixer, and applied by hand using a handboard and trowel.
The first coat is the 'scratch coat' applied to the correct thickness then 'keyed' and left to set.

The second coat is the 'float coat' mixed slightly different from the 'scratch' but applied in the same way.
This is the final coat so has to be finished correctly. There are a range of ways to finish render, usually dependent on
the texture required, or to match the existing render on the property.

Once the render has gone off it is usually painted, then repainted every other year or so.

Traditional Pebble dashing
This is done in much the same way as Rendering, but is finished with pebbles thrown
at the float coat instead of rubbing it up or texturing, as the pebble is the final finish.

IMPORTANT
We always knock off all existing render back to brick.
To go over existing render is in our opinion bad practice.
This is because, new render needs a good 'key' when going over existing render
the new will have to 'key' to the old, and usually when new render is required
this is because the old is damaged or dropping off.
Always insist that your render is fully knocked off back to brick,
Dont accept a cheap quick fix.

Below is an example of a quick once over existing dashing.
You can clearly see the original brick, then the scratch coat,
The old dashing and one thick coat of render.

When we started to remove all the layers of render, it came off very easy in places,
It came off in sheets around the windows. This was due to a bad key,
The newer smooth render did not bond correctly to the old dashing.

This is poor workmanship, and dangerous.
