Hi all,
I live in a circa 1900 brick built semi detached house. Walls are 9" solid and are in the main, in good condition. Outside has no render, pebble dash or paint.
All internal walls, barring some limited areas around windows have a pale, I assume lime-based render with a poor surface finish and contains some grit when examined after removal.
I have recently done a beginners course in plastering so I know the basics BUT I also know where my knowledge is limited. I have plastered over the lime render on the internal walls of our bedroom as a practice area - I also had to repair some areas under the window where a Rad was using Thistle bonding coat. I used Thistle Multi finish as a top coat with varying levels of success.... practise makes perfect.
Anyway, I need the stair way and landing skimming but lots of the render is blown and not stable for a top coat. I've had two lads round to quote for the work. Both said it would be fine to use thistle multi over the top of the render once a stable base coat is applied.
Having read the wiki and then various subsequent pages of advice on here and other plastering forums I'm worried that this is bad advice. The Lime lite and Dry coat products are too expensive to consider for a potentially large area of repairs to the render and I don't want to seal them in with a gypsum based multi finish only to have damp problems in the future.
If it helps, we intend to use a vinyl free paint finish to decorate and should funds allow in the summer, a stormdry product to the external walls once they are dry (compared to winter) therefore allowing the walls to dry and require little breathing.
Any advice would be welcome before I get back in touch with the plasterers. Reason I'm not doing this job myself? I want it done right first time.
