Exterior Hard Coat Stucco

Tim0282

I have a customer that closed an exterior door to his house. We fixed the plaster on the interior. He asked us to fill in the exterior. It is the old heavy textured stucco. Some else tried patching a window. It looks bad. They used a sand finish product and the texture is way wrong. It is supposed to look kind of like the material was thin and when you pull it out to texture, it sort of droops. What should I use?

genecarp

concrete with alittle extra portland, portland will get it creamie, not sure but it might work, lets see what a mason thinks

Frankawitz, Do you apply with a steel trowel? That's what it looks like. Then it must be wet enough to just kinda droop to make the texture. This house has been painted. Should I use an oil primer first? Then match color? Would you put wire mesh on before plastering? They just studded in the opening and put a piece of pink foam in there.
Thanks for your response.

Tim the pink foam is going to have to be removed and put up some OSB then roofing felt then wire mesh or metal ribbed lath, depending how deep the repair is you may need to do two coats, just make sure you score your base coat so that your scratch coat has someway to bond, then put on your finish, it sounds like you need to use a brush to texture to get the slum look. can you post a picture in the Gallery? or even on your post. I have a picture of a heavy texture on a exterior stucco job I did a few years back take a look at it, it should be listed under texture finishes, this house was built in 1912 and they used Gunite and shot it on the house. you may need a Grout bag and cut the end of the bag then just squeeze your stucco to form the texture. hope this helps.
