FAQS

ABOUT JOINT-IT SIMPLE™

What is Joint-It Simple™ ?

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.

Is Joint-It Simple™ a paving mortar or grout ?

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™.

What Colours does Joint-It Simple™ come in ?

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™.

Where is Joint-It Simple™ used ?

Joint-It Simple™ is used to fill the joints between natural stone and concrete paving slabs.

What is different about Joint-It Simple™ ?

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.

Does Joint-It Simple™ discolour any natural stone paving ?

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. In some cases where the stone is extremely porous, this may take longer, but any colour enhancement should disappear over time.

Can Joint-It Simple™ be used to re-grout an existing patio ?

Yes, provided the foundation is water permeable and the joints meet the minimum recommended width and depth (see above).

Why is being ‘cement-free’ important ?

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.

Why does Joint-It Simple™ being ‘water permeable’ matter ?

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.

BEFORE USING JOINT-IT SIMPLE™

What do I need to know before I use 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. 

What happens if I use too much water with Joint-It Simple™ ?

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.

What foundation should the paving be laid on to use Joint-It Simple™ ?

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.

What other preparations should be made before using Joint-It Simple™ ?

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.

USING JOINT-IT SIMPLE™

How do you use Joint-It Simple™ ?

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.

How long does it take to apply Joint-It Simple™ ?

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™.

Should joints be a specific size for using 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.

My bag of Joint-It Simple™ is hard when I take it out of the bucket ?

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.

Can Joint-It Simple™ be used with all stone ?

Joint-It Simple™ is suitable for use with all natural stone and concrete paving slabs including:

  • Porcelain* (see below)
  • Sandstone
  • Limestone
  • Slate**  (see below)
  • Concrete Slabs / Paving
  • Yorkstone
  • Granite**
  • Louisiana Stone
  • Oklahoma Stone
  • Quartz

* With Porcelain slabs, do I need to do anything differently ?

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.

** What do I need to know if I am using Slate or Granite ?

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.

What tools do you need to apply Joint-It Simple™ ?

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.

How long does Joint-It Simple™ take to set or harden ?

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.

How soon can you walk on the paving after applying Joint-It Simple™ ?

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.

WHEN NOT TO USE JOINT-IT SIMPLE™

In what weather conditions should Joint-It Simple™ not be used ?

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.

STORING JOINT-IT SIMPLE™

How long does Joint-It Simple™ keep in the bucket ?

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.

What is the shelf life of Joint-It Simple™ ?

Unopened, Joint-It Simple™ should keep for a minimum of 12 months when stored in a cool dry place.

What is the best way to store left-over Joint-It Simple™ ?

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 4 weeks. Watch our video to see the correct amount of water to use.
