How to repair missing outdoor patio grout?

Question

Hi my outdoor patio has bluestone pavers with chunks of grout missing between pavers.

Could you recommend a product I could use to fill in gaps between pavers?

Would something like this be suitable - https://www.bunnings.com.au/dunlop-800g-ready-to-go-coloured-grout-white_p6650123?store=6438&gclsrc=aw.ds&gad_source=1&gad_campaignid=21112196286&gclid=Cj0KCQiA4pvMBhDYARIsAGfgwvxCcGjLz75EoPYGHxcpeIvy1WCcdKJG1TzvRsrQT5SMjTIS7o25kj8aAulsEALw_wcB

Hello @Lozd0g

Yes, both products are rated for outdoor use and will anchor onto your blue stone pavers. This is on the condition that the gap is clean and free of debris. When you visit the store, you can see all the relevant specifications at the back of the packaging.

Yes, you can also use the Australian Builders 20kg Sand and Cement Mix Bag.

However, if you are after a smaller bag, I suggest looking at the Dingo 10kg Mortar Mix.

If you need further assistance, please let us know.

@EricL could you please confirmed the Dunlop ready-to-go grout / Dunlop flexible coloured grout are suitable for an outdoor patio with bluestone pavers?

Is it worth using something like this - https://www.bunnings.com.au/australian-builders-20kg-sand-and-cement-mix-bag_p0760612?store=6438&gclsrc=aw.ds&gad_source=1&gad_campaignid=21122993677&gbraid=0AAAAADtbEB_fwvIioeH4LDtvDobl-twHS&gclid=Cj0KCQiAhaHMBhD2ARIsAPAU_D6wA_7yw1J0dQ0QLp4qpEoXojfWP_MdRzDODxILRpj3YyPw0UEzidMaAnYPEALw_wcB

Hello @Lozd0g

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your paving gap.

If the gap is 5mm or less, you can use the Dunlop 800g Ready-To-Go Coloured Grout. However, if the gap goes past 5mm, I suggest using the Dunlop 1.5kg Flexible Coloured Grout - Slate Grey as it can cover gaps up to 8mm. However, if the gap is larger, I suggest using mortar to fill in the gaps. Please note that it is necessary to remove any loose or deteriorating grout before you apply the new grout.

My best advice is to remove or clean off any excess grout on the surface of the paver immediately with a large sponge to prevent staining the surface. I suggest rinsing the sponge often to prevent spreading the grout residue.

Here is a handy step-by-step guide: How To Grout Tiles (some of the techniques used are applicable to your project)

Please remember to wear personal protection such as gloves, goggles and a mask when working on your project.
