Exterior paint

Dont know much about this paint, but las time I used a "breatheable", " long lasting" barn paint on my white boarded house the algae was so thick three years later that I was thinking of using the lawnmower and leave it green. I hate paints, at least with limewash you know where you stand, usually very busy painting the rest of your life :wink:

The wall I need to paint is quite inaccessible without the aid of scaffolding due to it’s location above a single story Lean-to slate roof. There would be a lot of benefit in painting this wall white as it would throw a considerable amount of much needed light back towards the main property and secondly the wall itself being gnarled, ugly and patchy in colour and would look much better painted.
I think limewash might be impractical in this case due to the access problem and the regular maintenance that limewash requires however someone did suggest a limewash bound with tallow? (I think thats what they said) But I don’t know much about this or its durability. The 15 year maintenance on the silica paint sounds ideal in this situation and the other performance data also seems acceptable but I welcome any advice.

If the wall in is cement base render then any good masonary paint, or any other good quality paint that does not flake, will be fine. If this is the case the 15 year painting cycle, they claim, is very tempting.
If the wall is not cement base render ( ie,all lime based render) then average masonary contemporary paints will be unsuitable mainly due to lack of breatheability, this may be important to the wall construction as existing, and most important they will flake straight off.
I fully appreciate your concern regarding limewash, and rightly so, it will become a regular painting chore.
Is it important for the wall to be painted in breatheable paint ? . What kind of underlaying construction is there ?
( apologies if you are asked to repeat yourself from earlier post)

We've just limewashed the entire outside of our house (which was a fairly major job). I looked into silicate paints as well as various limewashes (for many of the same reasons you mention....inaccessibility, maintenance etc.)
In the end, we opted for Corical Lime (limewash with added marble dust). This claims very long levels of durability (10+ years in some cases) and I did pursue references with contacts at The National Trust maintenance team who confirmed that in certain locations they have had it in place for more than 5 years and it doesn't need recoating yet. This is especially true if you use the lime slurry basecoat as well.

I've just looked at that Earthborn exterior masonry paint to go on top of modern masonry paint but it says on the literature that the earthborn stuff shouldn't be put on over modern masonry paint in which case I'm left asking what's the point. If I was going on over something natural and breathable I'd be using lime wash so if I'm going over cement render I might as well go Dulux. Any counter arguments?

Very interesting thread for me as I'll have this decision - sorry Michael, nothing useful to add to your dilemma really except that contacting real experts and places that have used these paints is a very good idea.
Pford - we absolutely must have some piccies of your newly painted house! Very well done.
Vicky - absolutely right, we've often discussed that on here and unless you're going to strip off old unbreathing finishes there's no point using a breathable paint on top. Which is why many of us on here continue with Dulux and their ilk as stripping it all off is too arduous.
When we have the cement render stripped off and lime render put on the outside of our house I think I'll go with limewash. I prefer the thought of it being done every 5 years anyway as paint, all paint outside, gets tatty quickly. But it isn't a big house particularly and easy to access, I feel for people who need to erect scaffolding.

Pics will be forthcoming soon....
Now that it's over, I can reflect on the stripping of the , which we did by ourselves. It was a horrible job, over one of the harshest Winters we have had for years, but I have to say I am still pleased we did it. The house looks better and hopefully is feeling better now that it is breathing for the first time in years. It wasn't an expensive job (the major expense would be labour, but it's not a skilled undertaking).
As for scaffold, buy a tower! We bought one on eBay for the paint stripping and it has now been used for everything from gutter cleaning, wisteria pruning, roof repairs, cowl fitting, bulb changing, interior decorating and cleaning our windows! I wonder how we managed before we had the tower.
The other reason we chose the corical lime was that we have sections of flint in the house walls (the remains of an older building here before ours). Limewash by itself doesn't 'stick' to flint well and would have weathered very quickly...with the unlit base to the corical lime, we were able to get a good stable base.

Probably too much information here and difficult to describe but here goes:-
The arrangement of my property is a bit complicated in that I live in an old part of a seaside town which many years back was nothing more than a fishing village consequently, neighbouring properties are all in very close proximity.
The wall in question i.e. above the lean-to roof, is not rendered except for a foot or two at each end where it joins
neighbouring properties. Otherwise It’s just dark, patchy badly pointed solid 9” fair faced brickwork
My property is also built on the side of a hill and this part of the property (the wall and lean-to roof) which is separate from the main building, is partly below ground with the lean-to roof leaning towards the hill. The rooms below the lean-to roof i.e. the floor level, is about 8ft below ground (cut into the hill) and the living space is protected from the hill by a combination of slate on brick behind lime render or twin walled cavity brickwork lime rendered on the living space side. The area above ceiling level i.e. the lean-to loft is all above ground and the wall here is just 9” plain solid brick.
The bit I need to paint is above the lean-to lead flashing where the wall rises a further 4 or 5ft. This exposed part of the wall above the flashing has been really scruffily pointed in the past and I don’t know if its lime or cement.
I like the sound of ‘Corical Lime’ Pford75 but just the word marble conjures up ‘£’ signs in my head. Also is it easy to get hold of and would it really be durable enough in my seaside location?
I still like the idea of this particular brand of silicate paint (a) because it lasts a long time (b) because I’m not sure if the ugly pointing on this wall is lime or cement and the silicate paint will stick to both and allow breathability if required (c) as mentioned above, there are cement rendered areas at each end of the wall where it joins neighbouring properties and I would also like to paint over these.
I would still be interested to hear from anybody that may have used this product though.

My daughter has just had the volvox silicate masonry paint used on two exterior walls over the top of lime render. We won't know how good it is until some more time has elapsed but the company who rendered her house said it was excellent stuff.
It looks beautiful. I can't post pics because the lime render near the base of the wall got frozen and blown off before it set hard so it is currently being repaired.
