Plastering cottage

jap gt

I bought an old cottage, the exterior is a pebbledash finish, due to closing up windows and opening new ones, the pebbledash is bare looking in places and will be very hard to patch in

I want to plaster the exterior, i have washed the walls with a high pressure washer and removed all but the base layer of paint, i cant shift it, i had a plasterer looking at the job today and he said he would be very slow to plaster over the walls as is, he said the paintcoukd cause cracks in the plaster over time

Basically what i want help with is, anyone know of a product that will remove the paint, only option left to me is kango off all the pebbledash and plaster then

Cheers

I've rendered over an old part of our house which was pebble dashed. Did this 15 years ago and no sign of cracking in render on these surfaces. If nothing else, the dash gives a good key for the render to grip to. But YMMV.

Yeah he would have no problem plastering over the dash as its well keyed to the wall its the paint thats throwing him off doing it

If its your home do the job right one day with a kango will strip it back start fresh and be done with it

OP, depending on the age of the cottage, the pebble dash may be lime based because of the wall construction so you need to reflect on the breathability of the wall construction before you render.

Since you have knocked out for new windows, what is the wall construction?

Walls are built with an old style cavity block, the crowd that built the house in the 50's used to make their own blocks

Think about why this might be the case, get a second opinion at least. I presume the thinking here is that differential wetting & drying of the render will tend towards cracks due to uneven absorbency of the surface underneath. Maybe your solution is to keep the pebble dash as a surface to render but see how you can ensure even suction, absorbency across the walls. Have you considered external insulation - that'd kill two birds with one stone? Cavity block walls aren't known for efficiency wrt insulation.

I must look into the external insulation, i have all the interior slabbed with insulated plasterboard and drylined,

Is the external insulation expensive

The house is small less than 900 square feet must try and get a price for insulation
