How To Choose Porcelain Paving Grout
There are several factors to consider when selecting good porcelain paving grout, so let’s have a closer look at some of them:
Colours
When choosing outdoor porcelain tile grout, colour is significant. Pairing a dark grey grout with a warm-coloured beige tile can make your paving pop. Whereas a matching colour gives a sleek contemporary seamless look
Long-lasting
By its very nature, Porcelain is a durable and long-lasting material, so the last thing you need is your grout cracking and crumbling away after a few years. Epoxy grouts will undoubtedly last time, but we’ve also seen fantastic results with slurry and brush in grouts when applied correctly.
Durable
As mentioned above, you want your porcelain grout to last as long as your patio, so it must withstand adverse weather, staining and discolouration. Do you use a jet wash? If so, check the reviews; not all exterior grouts can withstand regular power washing!
Affordable
If you have a tiny patio, the cost of grouting porcelain tiles is relatively affordable, but as size increases, so does the price. Using epoxy grout for paving larger areas will be expensive, so slurry porcelain grouts and sweep-in options work out much more cost-effective for the average household.
Easy to apply
Nobody enjoys grouting. Who needs all that measuring, mixing and crawling about on your hands and knees? Nowadays, applying grout between porcelain tiles can be an effortless task that anyone can do!

Epoxy-based porcelain grouts provide a non-toxic, strong bond that doesn’t require a sealant and is easy to maintain. A mixture of two parts resin to one-part hardener produces a water-resistant bond which is virtually stain-resistant and won’t crack.
However, it’s important to note that improper application can cause severe issues and using epoxy grout is much more expensive than a traditional brush in exterior grouts.
Brush in
A brush-in grout is a dry mix that is easy to use and affordable. All you need to do is sweep it into the joints. It comes in various colours so that it can complement most porcelain patios.
So if you need something that’s no fuss, a brush in porcelain grout like EasyJoint could be the perfect solution.
Pre-mixed
The clue is in the name; these exterior porcelain patio grouts come ready to use; they are cement-based grouts known as slurry grouts. They are poured straight from the tub into the paving joints, and the excess is wiped away.
This type of grout for porcelain prevents weeds and can withstand pressure washing, so it is suitable for high-traffic areas.

FAQ’s
Do you need special grout for porcelain tiles?
Porcelain paving slabs are one of the most expensive options for patios, so whilst they do not theoretically require a special grout, using one specifically for porcelain will ensure no unsightly staining or discolouring, which can occur with a standard sand cement mix.
What do you put between porcelain slabs?
There are several options for filling the joints between porcelain paving stones. You could use traditional kiln dry sand, a jointing compound or porcelain tile grout.
How do you grout a porcelain patio?
Following the manufacturer’s instructions, apply the porcelain patio grout to the spaces between the pavers. Depending on which type you choose, you may need to wet the area, and in some cases, applying a sealant or pointing the grout for a better finish is recommended.
A top tip is to work in manageable areas. Once all the nooks and crannies are filled, you can then wipe away any residue, and it’s best not to walk on the site for 24 hours.
What gap should I leave between porcelain slabs?
According to experts, the spacing between the gaps in your porcelain pavers should be around 5mm wide.
Last Word
We hope this post has made choosing porcelain paving grout easier and given you an understanding of why it’s crucial, especially on an expensive material like porcelain.
Today’s technology and high-performance paving products are created to be highly robust and should last for many years, just like quality external porcelain paving.
Our top choice is Nexus ProJoint porcelain paving grout. It comes in two convenient 10 kg bags, is straightforward to apply, produces a stain- and weather-resistant joint filler with no shrinkage and is long-lasting.

Wipe away the residue as you go, and in a few hours, you’ll have a porcelain patio to be proud of!
