Product Information

However, if you use a pointing trowel to properly compact the compound when applying (instead of just brushing it in), you should get better results! We now notice that some of the slabs appear to have a grey film on them especially around the edges but some more so across other parts. It’ll begin to set as soon as the packet is opened, so it’s recommended you use it within 45 minutes. After mixing all three components together, the grout can be applied to the joints using a squeegee or brush.

This isn’t the case for all products though, so check their description before purchase if you want an all-weather option. Using a hose we soaked the area that we would be applying the product and started to pour the bag of Sika joint compound. What I am suggesting is only something that I would try so I can’t guarantee that it’ll work – Let me know if and how you get on! Another week later there appears to be a grey film over some parts of the slabs which a hard brushing and even scrubbing with some washing up liquid, fails to remove.Although the sandy affect could be the jointing compound still left on the patio, even if it looks like none is there. Once you’ve brushed the bulk of the product into the slabs, use a hose to wash any remaining grout into the cracks. Hi Corinne, I see it’s been 5 days since you posted, has the resin started to come away from your paving slabs? I still have another patio to tackle once I have finished this one, so want to make sure my little ant friends don’t fight back!

Hi Ray, you’re definitely going to get through a fair bit of paving compound with a depth of 2 inches! Thanks for getting back to me, the slabs being used are Marshalls Richmond Smooth Natural Paving Slab 450 x 450 x 32 mm. Having a landscaper do my patio in my garden, they are planning to use MOT type 1 as sub base, then put weed membrane on top and then sharp sand on top of the weed membrane. He had to grind out the old sand and cement mortar, but some places he missed, (got bored I reckon with a 200 sq metre patio! Hi Ste, Paving jointing compound, in my opinion, is a more user-friendly and a much quicker way to point but it doesn’t last as long as mortar.If you blast any of the old paving jointing compound out of between the paving slabs then I would just re-appy the jointing compound, this time being careful to not get it everywhere (I know it wasn’t you that applied the compound previously). In some places he just laid it over the cement and sand, but even where I know it was deep, it has still gone sandy, and every time I brush the terrace it comes away.

Once we had finished pointing the new patio we decided to give it a very light sprinkle to make sure that it would set. After drying i have noticed some staining to my Modak sandstone and i have washed with warm soapy water and tryed hyperchlorite on one slab to see if it would get rid of them and it hasnt any ideas on how to get these stains out as i want to seal it .I am worried the grey would come up either too dark or be a different colour grey to the slab which might look funny? It is also worth noting that all of the pictures in this post are patios that we have installed using this product! Since the jointing compound has no risk of staining the area, there would be no need to be careful which is where most of the time goes.
