Hi Neil sorry missed your comment - off with the dreaded covid!

Not at all if anything the joints on any porcelain paved surface will increase the effective R value as the profile is greater than the porcelain finish. We do understand what you mean about some traditional porcelain tile grouts used internally as these also have a very smooth finish, these external use products are much more robust.
Hi Joey - sorry for slight delay in reply. This is a completely different technology based on 2-component epoxy resin that is pre-coated and graded alluvial quartz sand. External porcelain tiles are designed to be laid to fall to suitable drainage in the same way as all external paving and so water should never sit on any paving unless drains ae blocked. There is some confusion over permeability in paving as technically all cement based concrete and mortar bedding mortars are permeable unless they are specifically designed to be waterproof, it is really just a question of degree. The GftK vdw 815+ and vdw 850+ joint mortars are permeable to allow water from below to escape through evaporation, as much as for water to drain from above, again it is a question of degree and this degree of permeability is a distinct advantage for faster installation with earlier grouting, and more effective and ecological performance in service. - There is a lot more information about all aspects of this subject on our website - You can find this on the Paving Jointing and Paving Jointing FAQS pages here: nccstreetscape.co.uk/paving-jointing.html - Also there is more background specifically on and relating to external porcelain tiles, porcelain paving and the issues of pointing / grouting / jointing on our Porcelain Paving & FAQS pages here: nccstreetscape.co.uk/type-of-paving-unit/porcelain-paving.html - If you would like more specific information and assistance for your projects you can email us to: technical@nccstreetscape.co.uk - Or call us when back in the office on Tuesday: 01257 266696 Hope this helps for now?
This isn't good practice, it's quick and dare I say lazy. You should always use exterior porcelain grout like Nexus or Fuga pave CH. You want a sealed, watertight grout that prevents water ingress below and hence frost lifting flags, even if they are slurry backed .
@@ivegotaporscheandalambo3318 Hi well that is an interesting combination of several misunderstandings and myths in the UK paving industry - Firstly confusing high performance 2-part jointing mortars with simple-part, vacuum packed, bag in a tub brush-ins that are totally unsuitable for porcelain and any long term paving jointing, and not just because it is permeable. There is a lot more information and support for contractors and specifiers alike with detailed technical explanations on our website here: nccstreetscape.co.uk/type-of-paving-unit/porcelain-paving-faqs.html Also you can reference the excellent independent PavingExpert website thoughts on this myths of permeable jointing with slabs and porcelain paving and frost damage in the UK here: www.pavingexpert.com/faq_permeable_mortars_01 If you have any further questions or would indeed like to fully understand all aspects of this please email our team at: technical@nccstreetscape.co.uk and we will be glad to assist you.
@@nccstreetscapevideo4554 I've used them all, they aren't high performance, sales pitch. 2 parts are ok, but not for porcelain, big bug bear is they green up and black up ( from horse's mouth). Smooth exterior porcelain grout only ie Fuga pave or Nexus. Do it once do it right. I call other ways lazy landscaping
Watch so many people that shows you how to grout - and as always like this video the mix is way to weak. It should always be a stiff smooth paste and not sloppy. Grout contracts and if the mixture is to weak ( i.e sloppy) in a short period of time it will break up leaving it to the elements and water ingress. The grout needs to be firm and pushed into the joints - yes more hard work but it will last a lifetime if done properly
Alan agreed for many cement based grouts where the water to cement ratio is critical - BUT the vdw 815 and 850 are 2-component, reaction hardening, epoxy resin based materials. This is a completely different technology whereby this flowable consistence that is ideal for self-compacting into the joints is also ideal for shrinkage-free hardening and curing, even at lower temperatures and in wet conditions.

Does this grout let any water through the joint or does it become water tight?

Is this similar to easy joint pro?

Does this reduce the R value of the tiles.?

We do understand what you mean about some traditional porcelain tile grouts used internally as these also have a very smooth finish, these external use products are much more robust.
what’s the difference between this and standard grout? are the joints still porous or will water sit on top? thanks
