Preparing for masonry paint
David wrote in message . .. (David) wrote in message . com... I'm repainting the outside of my pebbledashed house just now. Having pressure-washed the whole thing, much of the old paint and pebbledash is in lousy condition - flaking and crumbling - and needs sorting before I apply more paint. Question: what should I apply, a proprietary stabiliser or a PVA solution? If the latter, what dilution? Anybody???! Where's Mr Bone when you need him?! ;-) Stabiliser is thinner and more penetrative but you can end up using gallons of the stuff without any apparent improvement. Unless you have damp problems I'd use PVA diluted at 1:4, which will stay closer to the surface and may even form a film after a couple of coats. Whatever gives you a surface that doesn't suck in the first coat of paint is the one you need. |

Whatever gives you a surface that doesn't suck in the first coat of paint is the one you need. Thanks a lot for the advice, Stuart. Have duly drenched the house in dilute PVA and am now well underway with the paint, which seems to be taking well (although time will tell, I guess!) Anyway... I now need to buy myself a new set of ladders, as the current set (bought for a previous home) won't quite let me reach the eaves, and at that height from the ground I'm not going to take any daft risks. Question: given that the height of the eaves (ie the highest point I need to get my paintbrush to) is 7 metres from the ground, what minimum length of ladder do I need to buy? Just to be clear, this is the apex of a 7m high, flat vertical end-wall of the house. Should I be going for a double or triple extending ladder? As far as I can see, the disadvantage of the former is that unless you have a megabucks trade version with pulleys, it will be too long to extend safely and easily; am I right? Will it flex more than the triple? I expect someone's going to tell me a need a tower to be safe; really want to avoid the expense of that if I can! To be honest I don't know how I'd install a tower either, given constraints of the location. Second reason for the second ladder is that I also need a roofing ladder at the moment; my plan was therefore to obtain one of those gizmos you attach to a regular ladder, (eg http://tinyurl.com/nete)to convert it. Two birds with one stone, if you will. Does anybody have experience of using one of these attachments, are they safe and OK to use? I know a proper roofing ladder would be a better bet, but it will only be for very occasional use. Yes, I've considered hiring, but I will use this kit again occasionally in the future and it makes economic sense to buy. Also, it will be very much for weather dependent use, and IME as soon as you contact HSS to hire any fair-weather tool, it's a cue for the heavens to open! TIA David |
