external render

[russellsmiler]

Not sure if this should be here or in the plastering section, but i am doing up the external to my house and the paintwork on the render is relatively solid, however i can scrape it of were ther are cracks in the paint, this is quite random, if i know apply paint over the walls i will have a varying texture!! I have a surplus amount of a prduct called "Bond it" a gypsum product that is rollered onto smooth surfaces to accept plaster.. it so happens that this bondit is a good texturiser and if i applied it to all my render i would paint over and have a uniform finish, what i cannot assess is if this bond it will be suitable for this type of application... what i might be asking is if not what alternatives to uniform a surface, i dont really want to purchase a high build or textured paint as i already have my smooth masonry paint.

Many thanks
Russell

If you are talking about either of the 'Bond-it Pregrit' products, for plaster or render, then I would not recommend them for painting onto. They will form a waterproof film when dry that will more than likely cause adhesion issues, particularly if you are using a water-based masonry paint. I doubt the plaster version you mention would even be suitable for outdoor use anyway.

It's difficult to recommend a method for patching up bare areas without actually seeing the difference in texture. Perhaps you could upload a photo to help people here come up with something suitable for you?
