I was wondering if you guys on here could give me some help with my University project. I have been a landscape gardener through the last 5 summers when I am not doing my Product Design degree at Uni.
This year for my final project I have decided to design a product for pointing patios and other slab work.
There don't seem to be many good products on the market, only really the Point Master (www.pointmaster.co.uk).
I was wondering if you could let me know what techniques you use, if you have used any products to help and generally what annoys you about pointing. Any information at all would be gratefully appreciated.
Sorry for the late reply Euan
In 2003 I landscaped the former garden, Isington Mill, of Field Marshall Montgomery of El Alamein fame.
There was an existing feature, one of the mill stones, that Monty had placed as a door threshold to the front door and uses a tramway of Selborne brick stretchers on edge, with sand stone sandwiched between the two.
We decided to replicate this effect around the edge of the new drive using thin slithers of Indian sandstone (because we could not locate real sand stone) but because it was such a prominent feature, the pointing had to be a crisp weather struck joint.
Using a mixture (not sure of the exact ratio now) we mixed Kingsley yellow sand, cement and lime (for fluidity) into a fairly elastic and loose mix.
I bought two large jointing guns from screwfix which were similar to the Pointmaster guns.
For this job, with one constantly mixing and two landscapers jointing and pointing it worked well.
I must say, since the job, I have tried using them for different applications but I have not achived the same results every time.
