FAQS
Joint-It Simple is a water permeable, cement-free, ready-mixed paving jointing compound made from a mixture of specialist, non-hazardous, sands and glues.
Technically, Joint-It Simple is a compound and is different to a traditional paving mortar or grout because of the type of glue used. However, the terms mortar and grout are commonly used to describe many ready-mixed paving jointing products, including our unique Joint-It Simple.
Joint-It Simple comes in 3 colours – Neutral, Grey and Dark Grey. The lid on each bucket and a tick on the colour indicator on the side of each bucket of Joint-It Simple indicates the colour of the product inside.
Examples of a variety of natural stone paving can be viewed on our website with each colour of Joint-It Simple.
Joint-It Simple is used to fill the joints between natural stone and concrete paving slabs.
Contact with air makes Joint-It Simple harden which is why you must use plenty of water on your paving slabs before you open and tip-out the bag. Wet paving slabs prevent Joint-It Simple from penetrating into porous natural stone.
With Joint-It Simple you must use water.
The paving slabs must be wet before you tip out the product, otherwise Joint-It Simple may accentuate any natural discolouration in your paving slabs.
This is why Joint-It Simple can be applied in the rain, as well as in dry weather.
In cases where insufficient water has been used, Joint-It Simple may leave a residue that accentuates any natural discolouration in the stone.
This residue should weather-off over a period of 3-6 months. To avoid any potential problems when using Joint-It Simple, please watch our step-by-step video guide before you use our product.
Yes, provided the foundation is water permeable and the joints meet the minimum recommended width and depth (see above).
Joint-It Simple’s cement-free formulation is kinder to the environment than using a traditional sand and cement mixture. Your patio can be finished more quickly, and the jointing can be completed even if it is a wet day.
Contact with air makes Joint-It Simple harden which is why you must use plenty of water on your paving slabs before you open and tip-out the bag. Wet paving slabs prevent Joint-It Simple from penetrating into porous natural stone.
Being ‘water permeable’ is very important because it means that water/rain won’t lodge on your patio; it will drain down through the joints that have been jointed with Joint-It Simple to prevent your patio from flooding. Rain won’t crack the joints between your paving slabs which is why we say that Joint-It Simple is weed resistant.
If you decide to power-wash your patio, the water won’t lift Joint-It Simple out of the joints once the manufacturers’ guidelines have been met – it will drain down through the joints, which is why we say that Joint-It Simple is power-washer resistant.
We recommend that you avoid using a power-washer on your paving for a minimum of 30 days after applying Joint-It Simple.
We strongly recommend that you watch our step-by-step video guide before you start the foundations for your paving.
The single most important thing to remember when using Joint-It Simple is that you must keep the paving soaked with clean water as you work.
If you are working by yourself, work on small areas and keep wetting the paving as you joint your paved area. Ideally, ask someone else to keep wetting the paving for you as you work.
Remember, you must keep the paving saturated as you brush in the product.
Adding lots of water does not weaken Joint-It Simple because the product is water permeable. It is not possible to add too much water.
Not using enough water on the paving, especially in warm weather, dries out the product too quickly before it has been brushed into the joints.
Again, please take note to keep the paving wet at all times when brushing Joint-It Simple into joints.
To get the best results with Joint-It Simple, your foundation must also be water permeable. This means using a compacted hardcore foundation approximately 100-150mm / 4-6” (inches) deep. Space must be left to allow for 50mm / 2” (inches) of sand and cement and the depth of your paving slab to sit on top of the foundation.
The sand and cement layer, on top of the hardcore, must use 6 measures of sand to 1 measure of cement and the mixture should be semi-dry.
We recommend that you watch our step-by-step video guide before you start laying your foundation.
We recommend using Joint-It Premium Seal prior to laying paving where you are using Slate, Black/Blue Limestone & Honed Black Granite. These highly porous stones would benefits from being pre-sealed to prevent drawing any of the colour of Joint-It Simple into the stone.
If you have any overhanging flowers they should be tied back before you wet your paving ahead of applying Joint-It Simple.
This prevents any dye from the flower petals transferring to the paving while it is being soaked with water.
We strongly recommend that you watch our step-by-step video guide before you use Joint-It Simple.
Before emptying the product out of the bucket, you must saturate your paving with clean water. Then brush Joint-It Simple in to the joints. As you joint your paved area, keep wetting and re-wetting the paving as you work.
Depending on the size of your patio and the weather, Joint-It Simple should take approximately 30-40 minutes to apply to a 30m²/323 sq ft paved area.
It is important to keep the paving slabs wet as you brush-in Joint-It Simple.
To get the best results from Joint-It Simple, joints must be a minimum width of 3mm and a depth of 25mm for the joint to have stability when it is set. Watch our step-by-step video guide to see exactly what the ideal Joint-It Simple joint looks like.
If you are using bevelled paving slabs, the joint must be a minimum width of 3mm at the narrowest point between all of the slabs.
Joint-It Simple is tightly vacuum packed inside a tough plastic bag to prevent any air from reaching the product before it is ready to be used. Contact with air makes Joint-It Simple harden within a few hours which is why you must soak your paving slabs with lots of water before you open and tip out the bag.
Joint-It Simple is suitable for use with all natural stone and concrete paving slabs including:
- Porcelain
- Sandstone
- Limestone
- Slate
- Concrete Slabs / Paving
- Yorkstone
- Granite
- Louisiana Stone
- Oklahoma Stone
- Quartz
Because Porcelain is a smoother stone it doesn’t absorb water to the same degree as other natural stone products. To get the best results when using Joint-It Simple with Porcelain, we recommend that you keep both the top of the stone paving and the Joint-It Simple product saturated with clean water to make Joint-It Simple flow into the Porcelain joints more easily.
Also, if your Porcelain paving slabs are bevelled, make sure that the joint is 3mm wide at the narrowest point.
Slate and Granite paving slabs, even those from the same batch, may absorb water at different rates. When using Joint-It Simple with either granite or slate, pause briefly after soaking your paving, before opening the bucket of Joint-It Simple, to allow time for the stone to absorb the water. You may need to repeat the soaking process. If you notice small dots on your paving slabs, this indicates that part of the slab was of a harder density, and the residue should weather-off over a 3-6 month period.
Because Joint-It Simple is activated when it comes into contact with air, the product hardens more quickly in warmer climates.
At an average temperature of around 20° Celsius, Joint-It Simple should feel hard-to-touch after approximately 4 hours. In cooler climates it should take longer for the product to harden while in warmer climates it should harden more quickly.
You need 2 brushes to apply Joint-It Simple.
A hard bristle brush is used on the wet paving, to brush the product into the joints, and a soft bristle brush is used to finish the job. Watch our step-by-step video guide to see examples of suitable brushes.
Professional pavers often recommend you use a squeegee on very smooth stone such as granite, because the squeegee makes it easier to joint a smooth stone patio.
Make sure that brushes are clean before you start, and we recommend that you wash off any particles of the product when you have finished to stop it hardening on your brushes.
The paving should not be walked on for approximately 24 hours after application in temperatures of around 20° Celsius. We recommend that you gently test the joints to make sure they have set before walking on the paving. Local weather conditions will determine how quickly Joint-It Simple takes to fully harden/set.
Joint-It Simple can only be used on a permeable base. If the base is completely solid and impermeable, this product will not work. This is because Joint-It Simple is a water permeable product, meaning water is able to move through it. We recommend a hardcore mix of sand and cement at a ratio of 1:6.
If the temperature is forecast to drop near freezing or below freezing within 12 hours of application, Joint-It Simple should not be used, because the water will freeze as it hits the ground making it too difficult to sweep the product into the joints.
If the temperature is above 30°, we recommend that you wait until it is cooler in the evening or early morning before applying Joint-It Simple because water will evaporate too quickly to allow you to brush the product into the joints.
To use Joint-It Simple, joints must be a minimum of 3mm wide and 25mm deep. If joints are smaller than 3mm wide, we would highly recommend using our other product Joint-It Fine.
Unopened, Joint-It Simple should keep for a minimum of 12 months when stored in a cool dry place. It is important to make sure that the bucket is protected from any punctures or piercing as contact with air will start to harden the product.
Any unused Joint-It Simple should be put into the cleaned empty bucket (first having removed the plastic bag and cardboard from the bottom of the bucket) and covered with at least 2 inches of clean water. With the lid closed tightly, the left-over product should keep for approximately 12 weeks. Watch our video to see the correct amount of water to use.
Joint-It Supreme Colour Enhancer is an eco-friendly, effective combined colour enhancer and sealer for natural stone and concrete surfaces, including paving, paths, roof tiles and walls.
- Ready-to-use formulation
- Intensifies Colour
- Waterproof
- Stain Resistant
- Quick Drying
- Breathable
- Long lasting
- Keeps surfaces looking new
- Eco-Friendly
- Repels moss and lichen formation on surface
- Resistant to graffiti
Sealing your surfaces stops dirt and contaminants from penetrating the stone. It prevents weakening of the surface and keeps it looking new. With Joint-It Supreme Colour Enhancer, you get the added benefit of enhancing the natural colour of the stone also.
Joint-It Supreme Colour Enhancer is IN the surface not ON it, and the dirt is ON the stone not IN it. The dirt will never penetrate the stone once Joint-It Supreme Colour Enhancer has been applied, but occasionally you may need to clean the top of the stone – this will be much easier because the surface has been treated.
This is not the case. There is no reason to wait for efflorescence to come through. Once you have applied Joint-It Supreme Colour Enhancer, the water in the sealer pulls the efflorescence out of the stone. When this happens, you can simply brush it off. Now that you have sealed your surface, there is no moisture present to activate the natural salts, and efflorescence should not occur again!
Joint-It Supreme Colour Enhancer can be used immediately after you have finished the jointing process. There is no reason to wait for weeks or months. Our product is completely breathable so the stone can dry during and after the application process.
Coverage depends on the porosity, type and texture of the surface. All surfaces must be treated to saturation in 1-3 applications to ensure 100% efficacy of product. This varies with the substrate, however treating a small hidden area is recommended to calculate true consumption.
General coverage guideline:
Architectural concrete: 5 m²/l
Block paving: 5-8 m²/l
Porous natural stone (limestone, sandstone, slate): 2-5 m²/l
Low porosity stone (granite, marble, terracotta): 8-16 m²/l
We recommend using Joint-It Supreme Colour Enhancer prior to laying paving where you are using slate, black/blue limestone & honed black granite. These highly porous stones would benefit from being pre-treated to prevent drawing any of the colour of Joint-It Simple into the stone.
As soon as the surface is visibly dry it is safe to traffic, 4 hours is the norm in dry conditions.
Joint-It Colour Enhancer is completely water based and VOC free, formulated using chemically inert materials.
It is manufactured to ISO-9001: 2015 Quality management system and ISO-14001: 2015 Environmental management system.
Remove all surface contamination. Surfaces should be completely dry, clean and free from dust, dirt, oil, efflorescence, organic growth, coatings sealers and old paint films. All algae and mould should be treated and removed prior to application. Cracks in the surface should be repaired before use. Pressure wash up to 2500psi and use of a sterilising solution is advised.
Do not apply in wet, damp conditions or if rain is expected in 4 hours of application.
No. All previous coatings and treatments must be removed prior to using Joint-It Supreme Colour Enhancer. Due to the nature of sealers, Joint-It Supreme Colour Enhancer cannot be absorbed if there is an existing product in the surface.
If you’re not sure if the surface has been treated, pour a steady stream of water onto the surface. If the water absorbs into the surface, there is no sealer present and you can use Joint-It Supreme Colour Enhancer. If the water forms droplets on the surface, this means the substrate contains a sealer. This must be removed prior to applying Joint-It Supreme Colour Enhancer.
Do not apply Joint-It Supreme Colour Enhancer if rain is expected within 4 hours. Product works immediately but it may take up to 7 days to reach 100% efficacy.
Do not apply a second coat if initial coat has dried.
Do not apply during rain or frost or when temperature is below 5℃ or above 30℃.
Wear protective gloves, glasses and appropriate clothing while using Joint-It Supreme Colour Enhancer.
Keep pets and children away until surface has completely dried.
Keep out of reach of children.
Substrate temperature must be between 5℃ and 30℃.
Ambient temperature must be between 5℃ and 30℃.
Substrate moisture must be less than 5%.
Yes, we recommend using Joint-It So Clean to thoroughly clean your surface before applying Joint-It Supreme Colour Enhancer. To achieve full penetration into the pores of the surface, dirt and stains need to be removed.
Always test a small hidden area before beginning works. DO NOT DILUTE THIS PRODUCT.
Using a low-pressure spray, roller or brush, apply product to the point of saturation. Ensure application is from bottom to top on vertical surfaces. Take care not to let the product run. As the product starts to soak into the substrate, add a second coat, if required. DO NOT ALLOW PRODUCT TO DRY BETWEEN APPLICATIONS. Product will start to work immediately but may take up to 7 days to reach 100% efficacy.
Clean equipment and tools immediately with water after you have finished.
No, Joint-It Supreme Colour Enhancer will not work on non-porous surfaces. This product must be absorbed into the substrate to work, and porcelain has almost no absorbency.

Joint-It Fine is a weed resistant paving jointing sand, which has been developed specifically for use with block/brick paving, most commonly used on driveways or more heavily trafficked areas. Where other sands and grouts can crack allowing weeds to flourish, Joint-It Fine is naturally formulated to increase pH levels in the joints to repel weed and windborne weed seed growth in the joints.
It is formulated using 100% natural raw materials stabilised with an innovative, organic binding technology that expands on contact with rain, preventing permanent cracks and repairing any hairline cracks that may have appeared due to normal use and traffic.
It is the perfect product to use for new block paving jobs and for jobs that need rejointing.
- Sweep sand into clean and dry joints
- Compact the sand with a vibrating plate.
- Using a leaf blower, clean away excess product from the surface.
- Wet the paving with a light, fine spray.
- Wait 5-10 minutes.
- Thoroughly soak the paving.
Joint-It Fine is a paving jointing sand for joints under 3mm, and Joint-It Simple is a paving jointing mortar for joints min 3mm wide and 25mm deep.
Always test a small hidden portion of the surface before applying Joint-It Fine™ to the entire area to ensure appearance and performance is acceptable.
Brush away any leaves, debris or heavy growth before use.
The innovative binding technology in Joint-It Fine creates a joint that constantly repairs any small cracks in the joints caused by heavy traffic. Rain swells the 100% raw, organic, natural ingredients in the sand, to consistently repair all microcracks.
The cutting-edge technology used to prevent weed growth raises the pH levels in the joint, preventing weeds from rooting.
Yes Joint-It Fine is an entirely eco-friendly, non-hazardous product. It is made from 100% natural raw materials.
No. Our jointing sand is completely free of polymers and cement. The reason is, polymer paving jointing sands don’t offer the same flexibility as Joint-It Fine. While they may stop weed growth initially, they won’t continue to self-repair cracks, causing weeds to grow over time. Once activated, a polymer sand remains tightly bound causing cracks to get larger.
No. Joint-It Fine must be applied in dry weather conditions at temperatures above 2℃. There is no requirement to protect paving from rain after installation.
Joint-It Fine can ONLY be used on a water-permeable base.
Each bag of Joint-It Fine will cover approximately 9-10m² of block/brick paving where the joints are less than 3mm wide.
Joint-It Fine is suitable for joints UNDER 3MM WIDE. If your joints are larger than 3mm wide, we recommend using Joint-It Simple.
Grey & Neutral in 20KG bags.
