Have a reasonably large patio & path area of Indian Sandstone ... (175 sq m)

Laid 2 years ago ... and now after 2nd winter - quite a lot of the pointing is coming away ... on advice here I specified standard mortar pointing rather than any of the pour-in mixes.

(The company used also always used mortar pointing. )

I need to re-point, is this a case of just raking it out and doing same again ... 3:1 mix packed in and tooled up ?
or is there any mileage out of using a pointing 'gun'

If the latter, is there anything better than just a semi-wet mix, additives, polymer grouts etc ?

Secondly ... there are a coupe of loose slabs ... not rocking but you can tell by sound that they are not fixed to the bed .. is re-pointing enough ( as still fully supported) or as I'm assuming it is necessary to removes and re-lay ?

Those hollow slabs could be left i you cant pull them out. However if they lift up, re fix.

If you've got to repoint the whole job its a good idea to remove the loose slabs and relay. Otherwise if you re-point and the slabs are still loose then it wont be long before the pointing around the loose slabs starts to fail again

OK ... thanks for comments on that ... what about the product to use / pointing gun ?

I would always say easipoint for your pointing mix and the gun should be a Durgun 45.

But I do sell both products so you could say that my answer is not very objective :laugh:

I'll go Google easipoint ... not heard of this.

Can you give me a clue as to how much this costs ?

I have been given a 'new' pointing gun ... boxed set of tubes, nozzles etc. .... by local Brickie ... he tried it once and went back to a gauging trowel

although he was putting in standard bricklaying mortar.

Comments on-line suggest standard sand cement not much good in the guns.

You will be paying in the region of Â£25 + VAT ber bag for easipoint. A bag should cover 12-15m2 on gaps of 10mm.

If you do go for easipoint follow the instructions on the bag to the absolute letter. One of the most important things what a lot of people dont do is to allow the mix to go off in the bucket for 5 minutes before giving it a further mix. This activates a component of easipoint which makes it last longer in the gun

There was a few comments on another thread about the qtys of water I know LLL has his opinion on gun pointing personally I'd take it all out pressure wash it and resin point it yourself

i find you need a little more water than they state,more like 4.5 to 5 litres
plastering sand and cement works through the guns and is very cheap but not as nice a finish as easipoint
epoxy mortar costs an arm and a leg and is only for the oligarchs
