Note: I saw it fit to create a new topic based upon the comments in my previous thread in regards to pointing a Marshalls Woodstone patio.
As I have created tight joints ranging from 2mm to 8mm (see below photos), the general advice seems to be to fill them with KDS, however I fear that this will in deed wash out of the larger joints. So, what alternatives are there to KDS with slightly larger (and heavier) grains but still suitable for joint filling? The two products I can see are:
- Bradstone's 3mm Permeable Jointing Aggregate 3mm
- 1 - 4 mm crushed granite aggregate supplied by mansfield-sand (?).
- Granite dust which ranges from 1 to 6mm.
These could both be the same aggregate though, does anyone know or have any specific recommendations?
That thread talks about all of the options including KDS, mortar, polymerics and resins. From the discussion, KDS seems to be the first option to try despite it possibly washing out. So, I'm wondering what you guys think about similar aggregates which also contain slightly larger grains.
Seems like it would make a good new thread for anyone in the future also wanting to know about KDS alternatives as opposed to a long discussion about various solutions for a particular job.

KDS is cheap as chips
try it and if you dont like it go for the more expensive fix

Evis you have asked the same question on 2 separate threads and for some reason not accepting the answers given, there is no alternative for kiln dried sand as its main use for paving is to go in-between the joints of block paving prior to the final compaction
the option offered to you was a quick fix due to the issue your faced with which is basically the balls up with the laying of 80m2 Marshalls Woodstone patio without any joints
if you use any of the resin based jointing products the joints at 2mm are not wide enough for it to last which has already been mentioned to you
as per the Marshalls Woodstone product file as listed below
it says If laid flat, Woodstone Sleeper joints should be
either open (25-30mm) and completely free
draining or 8-15mm wide and fully pointed
with mortar (or similar jointing product)
seeing as you don't believe anyone here phone Marshalls direct and ask to speak to someone in the technical department and ask them if their Weatherpoint 365 will stand the test of time with a 2mm gap and I will bet you a £1 what the answer will be
0845 820 5000
and then come back and let us know what they say as I for one am not prepared to put my 32 years experience on the line and say pointing a 2mm gap is good enough to last the 10 years that I guarantee my work for - because it ain't OK

Fellas, I'm not hear to waste anyones time, troll the forum OR not take on board anyones advice. I would have thought that it should be clear by now that I have taken it on board ???. Hence, I have opted for the 'dry sand' method as many of you suggested to try first. However, as opposed to buying in 'cheap' KDS which, as you guys have already mentioned is used for block paving which only has narrow joints but may wash out on larger joints, I have had a look around and it seems that other 'sand' products are available to deal with a range of slightly wider gaps (usually for permeable block paving) than those found on standard block paving.
I am now looking for your opinions on these products, and no longer asking whether I can use this slurry or that resin or that mortar, these questions where all answered wonderfully in the thread about 'various pointing methods'. I started this thread purely asking about crushed rocks with a larger range of grain sizes than KDS which may prevent any of the larger gaps being washed out.
i have enjoyed these 2 threads the most.
just imagine what the conversation in the pub about this would be like!
elvis: i am not an expert, but you should be able to find a washed and dried silica sand, that will come in different sizes,
0.2 to 0.63
0.4 to 0.8
0.8 to 1.2
and getting larger from here.
i dont know the prices in the UK but here in the Peoples Republic of Cork its about €7.50 inc vat
