Rendering over pebbledash Ask your questions and find answers on many subjects relating to plastering and dry lining

[Ginga]

Hi all , been plastering and damp proofing for 25 years but have come across a new problem , a client wants me to render over her painted pebbledashing , i normally would take off the dashing but it is very sound , do you think it would hold up with 2 coats of PVA and a PVA in the scratch coat enough for me to gaurentee it ? or does anyone know of a better adhesive or method

Many Thanks

Ginga
great site by the way

We would go for SBR rather than PVA Ginga and get a thin scratch coat on while the 2nd coat of SBR was still tacky. Should stay put but obviously we are in no position to guarentee.

Hi,

Just joined the forum. looks great.

I have a similar issue to the one below. My house has old pebble dash with several coats of paint on it (The last one was Dulux) I want to smooth render the whole property (or have someone else do it), and want a perfect finish.

The answer below is useful, but is there a 'By the book method' that is 100% failsafe? Ideas that come to mind (Apart from hacking it all off) are to mesh the wall first to give a stable base, but I am guessing.

Lastly what would the correct mix be and what are the materials used.

Thanks

Dan

No failsafe method other than to hack off Dan. See our mortar mixes project for the mix and materials.
