Choosing the right grout type for your porcelain paving project

Choosing the right grout type for your porcelain paving project

To achieve the perfect finish with your Select Stone porcelain paving you will need a good grout or jointing compound. Grout and jointing fill the gaps between the slabs to ensure tiles are aligned for a polished look, whilst ensuring the tiles durability and strength. 

When it comes to choosing the right grout type for your project with porcelain tiles, you will want to pick from the following three which we recommend:

  1. Premjoint Fine
  2. Fuga-pave FLEX CH GROUT
  3. Flowpoint Fine

This blog will outline the difference of each of these 3 grouts so you can make an informed decision over which will suit your project the best.

Premjoint Fine

Single part polymeric compound

Pricepoint: £££

Say hello to this super easy brush-in paving solution, although this is one of the more expensive options per m2 to install, it is one of the quickest processes and is suitable for most types of paving. Once set on a permeable bed, it provides a permeable paving solution, meaning it will allow rain water and air to penetrate through.

There is no waste here, with this product, as any leftover material can be reused. It is resistant to freeze/thaw weather conditions so can be applied in any weather.

Premjoint Fine colour availability

  • Cosmic Black
  • Storm Grey
  • Natural Cashmere

We recommend the Premjoint Fine over Premjoint Coarse for porcelain paving. The fine grade comes in 3 bespoke colours, each with an excellent colour stability for a consistent finish.

Brush-in application (it’s quick and easy)
  1. Wet the paving thoroughly first
  2. Add the dry compound by pushing it into the paving joints with a squeegee and brush
  3. Sweep and leave it!
  4. For a neater finish run a jointer over the material once dried. But don’t press too hard.
  5. You can walk on it within 24-48 hours
To get the best lifespan jet wash sparingly, avoiding direct contact with the joints.

Meet this technologically advanced, cement-based, non-permeable paving grout - this paving is perfect for both internal and external applications. It is perfect for those who are looking to achieve a sleek, contemporary look with their porcelain paving.

Its application process requires less effort than traditional application methods, however in comparison to brush-in grouts like Premjoint, it will take slightly longer to do, and can only be applied in dry weather conditions.

Fuga-pave FLEX CH GROUT application

This requires a minimum of 2 people to complete the job and protective clothing to be worn to avoid eye and skin contact with the mixture. Grout does not come pre-mixed.
  1. Mix the contents of the bag with a specific ratio of water
  2. Ensure joints are as dry as possible, no standing water in them when you apply the grout
  3. Apply to joints with a grout float
  4. Once touch dry (don’t wait until bone dry), wipe surfaces clean with a damp sponge.
  5. Sponge off diagonally across the joints to avoid dragging any paving grout out
  6. Repeat steps 4 and 5 for a second clean to ensure there is no grout residue

Tools such as Washboys will make easy work of wiping surfaces clean, if you are going to be applying grout regularly we advise this is something you invest in!

Flowpoint Fine

Cementous-based slurry paving grout

Flowpoint is a great option if you’re looking for a smooth, contemporary finish on a budget. This option is the most cost effective, however is the hardest application if you have never done it before.

The advantage of slurry paving grouts over single part polymeric grouts like Premjoint is that grouts like Flowpoint form a slightly stronger bond so is suitable for both permeable and non-permeable bases. It results in strong, durable, weed-free paving joints! 

Flowpoint Fine colour availability

  • Charcoal
  • Natural Grey

Although Flowpoint has limited colour availability, its finer granules give it a more grout-like, modern appearance. We recommend Flowpoint Fine for porcelain paving.

Person measuring joint width and depth

A note about joint widths and depths

Before installing your paving, it is worth discussing with your installer what joint depth and width will be used between the tiles, as this can affect how much area coverage you will get per product.

For calculating joint depth it depends on what tiles you are using. For example with our Select Stone porcelain paving, our tiles require a 20mm depth.

For calculating joint width it depends on what grout you will be using. Below is a chart that outlines the recommended grout width for each of the products we have featured:


Grout joints from 2 to 50mm wide


Grout joints between 5 and 20mm wide.

Fuga Pave

Grout joints from 2mm to 20mm wide.

Avoid butt-jointing (where there is no gap left between slabs) at all costs as this can cause damage to the tiles when pressure is applied.

Conclusion is to 'get the good stuff'


Each of these grouts are a lot easier to apply than traditional methods, but if you are still unsure which grout is best for your project, feel free to ask us so we can advise the best grout for your application. We can also put you in touch with an approved Select installer if you require help with the application process or colour matching.
