I need to re-grout a large patio, sand and cement only seems to last a year before falling out, I've seen some resin based solutions, or some expensive looking grout bags, whats the best quality vs budget solution to this please?

Something grey, not too expensive, easy to do and long lasting?

Thanks

Following.
I've just pressure washed my patio yesterday and blown half the grout away. I used a premixed recommended grout last year (can't remember the name) bit obviously this hasn't worked the best.

I used EasyJoint on mine last summer, only a year in but it still looks as good as the day it went down,

Very easy to use however I would advise taking your time pressing in once swept and going over a couple of times

Only negative i found was each tub doesn’t go very far however that’ll purely depend on the particular flags/spacing

I used one of the resin based grouts about a year ago, think it was by Sikaflex but can't remember the brand name, about £35 for a tub and I needed 3 for about 40sqm.

It's pretty good, it isn't a case of just brushing it in like they'd have tou believe.

It took me quite and while and I resorted to using my hands rather than a pointing trowel.

Just pressure washed it and nothing came out so pretty happy. Still think there's a better solution just not sure it's been invented.

The price has shot under 50% on Amazon since CV 19 so I’m waiting.

Plenty of other jobs to do

Sometimes I think amazon have clever algorithms that jack prices to individuals.

GftK vdw 815 Epoxy Paving Joint Mortar

Or there equivalent depending on what your grouting. (Size etc)

Easily applied don't have to get in hands and knees just flood the area mix and tip out the bucket and squgee it in. YouTube it. Once set will last for years. Used commercially and for residential and can be jet washed etc without damage.

I've used flowpoint on a couple of patios now. 25kg bag for £25 or thereabouts. Super easy to apply, flows into all the nooks and crannies and sets hard. Just don't wash it down the drains!

Found this stuff last night, looks pretty serious, if a little expensive, any experience of it?

I bet you're just brushing it in dry? Dig out what you can, make a damp mix of 3:1 and get it nicely compacted in the joint with a tuck pointer. Finish with a broom handle/finger trowel. Plenty of "how to" videos on YouTube.

It's not the material it's the way you're using it smile

What type of slabs are you pointing? size of joints?

They are a sandstone, and the joints are oversized, just the way it was laid, probably a good 5cm

Previous pointing was indeed pushed in with a trowel, not just swept in

First, make sure you grind them all out properly.

Got a few options.

sharp sand and cement, mixed like brick muck, maybe a bit dryer, then gun into the joints, pc cox gun from screw fix is good. then strike off but requires some skill to do nicely

marshalls weather point 365. much better imo than easyjoint, follow instructions properly.

flowpoint. pretty cheap and will do a great job but not really aimed at diy. could go drastically wrong. between myself and mates who used it (porcelain though) its better to slurry on and then washday off, too much water when cleaning will damage the joints, not enough and you wont the stuff off.

gtfk. vdw800 will be expensive and tbh i dont really think its a great deal better than marshalls 365, well it is better but its a lot more money and in my experience 365 holds up alright to be fair.

easyjoint, nexus, sika are not very well regarded in the trade.

I've always used a wet 4.1 mix with a slug of mortar plastisciser and a handful of glass fibre strands thrown into the mix then point up .
Most will consider this overkill but I used it on the front where I park cars and the joints in Indian sand stone paving have been fine since I laid it about 8 years ago .

5cm! I think sand and cement would be the way to go, that’s too much for most polymeric type products, plus it will cost a fair bit for the stuff, especially if the joints are deep. 4-1 grit sand/cement or 3 grit 1 soft sand 1 cement to make it a bit easier to work. When I’ve had to point joints that width I usually use an arrowhead profile. Ignore all that if you meant to type 5mmlaugh

Just thought I would add to this as I've been working on my patio. If you research the best product Sika Fastfix comes up top all the time with glowing recommendations. Don't use it it's rubbish. I've just spent a day and a half digging it out of my patio joints to replace, and all I needed was a screwdriver because it's so soft. It's very rough grain and not at all durable, wearing away from the joints very quickly, and the charcoal will stain the slabs despite the exagerated claims made by the product. Read all the one star reviews on Amazon about how poor it is. Also here on YouTube 'Sika Pave Fix Fail'

a professional complains about having to re grout a patio at his own expense because the product failed.

Is it possible to get some "luminous resin" mix that could be used to create a pattern?

I have a crazy idea for a small crazy paved bit to create a shape that would have a more visible outline!
Maybe I'll just use a different colour grout or something....

I used this for our patio! Lasted a good few years before we moved, including several pressure washers. Always came up like new.

Given the thread is 2yrs old he's probably in a good place to give you a long term update.
