I'm looking for some advice on re-pointing a small but complex area of patio/steps.
I've just moved into a property where the back garden is nearly all composed of small element buff dyed-concrete paving and 'Cotswold' walls - I suspect Bradstone or similar. The paving units are small and the surface is heavily riven. I have some photos but I can't see how to attach them - if anyone's interested I can send them separately.
Some of the paving slabs are loose, which I will need to re-bed with sand/cement mortar, but most of the joints are shot and the whole lot will need to be re-pointed. There is some soil weeds in the degraded joints, which I'll have to deal with beforehand.
I am not a professional (at least not at this type of work!) but I'd call myself an enthusiastic DIYer and quite happy to have a stab at this myself.
My issue is with what type of jointing material to use. The factors are:
The paving elements are very small, and if I get some cement staining along the edges of the joints then it will amount to a heck of a lot of staining overall.
There are a lot of steps and the unbroken flat areas are small. Therefore trying to use a big mix of wet slurry, as seen on countless Youtube videos, could end up completely out of control.
The surface is heavily riven, so it might be difficult to sweep away any slurry.
I live in west Wales, possibly the wettest place on the planet, so the chance of an extended dry period is slim - and the chance of an unexpected downpour high. Anything that can be done in the rain would be welcomed.
All this is leading me towards Marshall's Weatherpoint 365 polymeric aggregate, for the following reasons:
It is tolerant of wet conditions - indeed needs a wet surface
It appears that I can use as much or as little as I want at a time and I'm not committed to a given quantity or area.
There is apparently no waste and I can re-use any surplus.
It's currently on offer at Travis Perkins!
This is what I will go with unless I hear anything from you guys to the contrary. Any advice will be hugely welcome.
Thanks in advance
