Joint-It Porcelain Epoxy Grout
The Newest Innovation in External Porcelain Grout
We have been asked to develop a new solution to grouting outdoor porcelain paving. After a long, painstaking research and development phase – we are excited to finally launch our brand new epoxy grout product for professional pavers and landscapers.
Joint-It Porcelain Epoxy Grout is unlike any other jointing product on the market for outdoor porcelain patios. It can be used on a joint width of between 1mm and 10mm but is best suited for a 2mm to 5mm joint width.
Application Gun:
Joint-It Porcelain Epoxy Grout can be applied with a manual gun or an electric gun. The manual gun is suitable for touch-up jobs or testing. The electric gun is recommended if it is a larger area or a full patio that needs jointing.
Application Tips:
Always submerge the tubes in hot water for 30 minutes before use. This ensures the best results and an effortless application.
Choosing your colour: Product images and colour names are provided as a guide only. The finished appearance of Raven, Tan and Grey can vary depending on the surrounding paving, joint width, lighting conditions, and whether the area is viewed in direct sunlight, shade, or lower evening light. Screen settings may also affect how colours appear online. We strongly recommend applying the product to a spare tile or small test area and allowing it to cure fully before completing the full installation, to ensure you are happy with the finished colour.
Three Colours:
Joint-It Porcelain Epoxy Grout is available in Tan, Grey and Raven.
We have developed a product for you that is:

No More Messy Clean Up
Gone are the days of racing against the clock to wash cement-based grouting products off your porcelain paving before it stains. Joint-It Porcelain Epoxy Grout just peels right off with a blade. Clean and simple jointing!
Incomparable Strength

The strength and durability of this product is like none other.
Just look at how it bonded these large porcelain slabs together when we tried to lift this patio during our testing phase.
Extremely Low Maintenance
Part of the reason porcelain paving has become so popular is due to its easy-to-keep-clean benefits. Until now, there was no grouting product on the market that was completely rock solid/non-permeable and would not absorb any dirt and grime.
Dog and cat urine have an acidic pH that can cause serious damage to slabs and joints, especially if not cleaned right away, leading to both aesthetic and financial damages. Urine can cause corrosion, so having your slabs sealed can prevent this from happening. If you have pets who frequent your paving or patio, it is good practice to wash it every few days to prevent long-term damage to the joints and slabs.

Please visit our Joint-It Porcelain Epoxy Grout calculator to estimate the amount of grout you will need for your project.
If you have any leftover product within a tube, you can put the cap back on and use within 1 month on a different patio.
Joint-It Porcelain Epoxy Grout can be used on joints with a width of between 1mm and 10mm. The product is best suited for a 2mm to 5mm joint width.
Yes – Joint-It Porcelain Epoxy Grout is resistant to up to 7500 PSI water pressure where application guidelines have been followed correctly.
We recommend maintaining your patio with a suitable patio cleaner every two to three months, depending on how much shade the area receives.
Joint-It Porcelain Epoxy Grout comes with a Colourfast Warranty, subject to the warranty guidelines. If the grout appears discoloured, this is likely to be surface staining rather than a change to the colour of the grout itself.
If the patio has not been maintained for some time and the Joint-It Porcelain Epoxy Grout appears to have changed colour, Joint-It Grout Haze Remover can be used to restore the grout to its original colour. Watch our video for guidance on how to use it.
In rare cases, Joint-It Porcelain Epoxy Grout may turn white shortly after application. This can be caused by a reaction between the epoxy within the product and moisture carrying airborne contaminants, including PM10 pollution and carbon. If this occurs, it will happen within the first six hours after application.
There is no need for concern. After a few days, Joint-It Grout Haze Remover can be used to restore the grout. Watch our video for guidance on how to use it.

Each tub of Joint-It Anti Bonding Wax will cover approximately 40 – 50m2. Actual coverage will vary depending on the amount of wax applied over the joints.
In some cases the product may initially have a slightly glossy appearance, but this will tone down after a few weeks to a matte finish.
Joint-It Porcelain Epoxy Grout can be used only on a surface where the finishing scraper can be smoothly pulled across the top of the paving to scrape off the excess. It cannot be used on paving where the edge of the stone has a handcuff finish.
Joint-It Porcelain Epoxy Grout is primarily designed for use with porcelain paving. The smooth surface of porcelain makes it easier to scrape away excess product during application.
Contractors have also reported successful results when using the product with certain types of natural stone, including sandstone and granite. When using this method, apply heavy-duty industrial masking tape to either side of the joint before applying the grout. Scrape away the excess product the following morning, then remove the masking tape.
If you intend to use Joint-It Porcelain Epoxy Grout on natural stone, we recommend carrying out a small test area first.
This product can be used to:
Adhere paving slabs to a wall on a small area (as long as the area is dry).

BEFORE USE
We strongly recommend that you watch our application video before you start the foundations for your paving.
Ensure paving is clean and dry and that rain is not expected before you have completed Step 3 of the application.
Product should not be used below 5°C.
Always submerge the tubes in hot water for at least 30 minutes prior to application of Joint-It Porcelain Epoxy Grout. This ensures that the product inside the tubes mix easily when coming out of the application gun. In addition, we strongly recommend using an electric application gun for an effortless application.

The product may change colour depending on air quality, especially in areas near the sea with high salt levels in the air. This discolouration may last for up to 24 months, but the product should return to its original colour; however, this occurrence is rare.
Product should not be used below 5°C or above 25°C.
Paving tiles need to be laid securely with no movement in the slabs.
HOW TO USE
Watch our step by step guide on how to apply Joint-It Porcelain Epoxy Grout.
If you have any questions about the application or otherwise, please contact us at info@jointit.com
To apply the Joint-It Anti Bonding Wax, use the sponge provided to rub the wax in a quick, circular motion. This is to ensure that the wax is loosened and almost liquid-like, so that there are no lumps of wax that may go down into the joints, preventing the Joint-It Porcelain Epoxy Grout from bonding properly over time.
When applying the wax with the sponge provided along the top of the paving either side of the joint, apply the wax lightly and with not too much pressure on the sponge. By applying too much pressure on the sponge, it may disintegrate the sponge. If you feel the sponge has disintegrated before you have finished the tub of wax, any type of a sponge of a similar grade will perform the same way.
We recommend applying Joint-It Anti Bonding Wax sparingly along the top edge of the tile beside the joint, ensuring that no wax seeps into the joint. If wax gets into the joint and onto the sides of the tile, it can prevent Joint-It Porcelain Epoxy Grout from bonding properly over time.
A number of finishing tools have been specifically designed to leave an even, smooth finish on the joints. The flat bar finishing tool is best used for a smooth flush finish on joints that are between 3-5mm wide.
For the best finish, we recommend using the flat bar finishing tool.
If the product remains in the mixing nozzle for more than 20 minutes without being used, the material inside the nozzle may begin to harden. In this case, the nozzle will need to be replaced before continuing. Each tube of Joint-It Porcelain Epoxy Grout is supplied with a mixing nozzle.
- The Electric Application Gun is intended for professional patio jobs. For touch-up jobs or testing, we recommend using the Manual Application Gun.
- The Electric Application Gun has six settings. We recommend using lower settings when getting familiar with using the Electric Application Gun, and you can increase the speed at your discretion.
- It is okay to use the Electric Application Gun without cutting the tip off the nozzle when using Settings 1-3. Just make sure to use it on a low setting, otherwise it will put additional pressure on the tubes.
- If you would like to use a faster setting, you will need to cut the end of the nozzle to create a larger gap. This is to prevent pressure building up in the tubes.
- If you would like to adjust the settings from three to six, whereby the product will come out faster, we recommend that you also cut a little bit off the top of the nozzle to allow more product to come out. Failing to cut the nozzle with the gun running at full capacity will put the wall of the tubes under increased pressure.
- The electric application gun comes with two rechargeable batteries. We recommend charging both batteries prior to use.
- Make sure the tubes are positioned correctly in the Electric Application Gun before use. Watch this Tips & Advice video where we demonstrate how to position the tubes correctly in the Electric Application Gun.
The Manual Application Gun is suitable for very small areas (up to 1m²) or touch-ups, while we recommend the Electric Application Gun for larger applications and full patio jobs.
WHEN NOT TO USE
Joint-It Porcelain Epoxy Grout is only for paving joints between 1-10mm wide and at least 10mm deep. The product works best with a 2mm to 5mm joint width.
The paving must be clean and dry before application and there should be no rain expected for the initial part of the application.
If it starts to rain after you have run the finishing tool along the joints (step 3), this is no problem and will not affect product performance.
STORAGE
If you have product left in the tube, remove and dispose of the mixing nozzle, re-cap the tube and store it safely until you are ready to use it again.
Joint-It Porcelain Epoxy Grout must be stored in original packaging in an ambient, dry area. Storing incorrectly may affect the characteristics of the product.
The shelf life of Joint-It Porcelain Epoxy Grout is 7 years, provided it is stored correctly in a cool environment.
The Joint-It Anti Bonding Wax has an indefinite shelf life, dependent on storage in a cool environment.
