Brand New Paving Project

This is for paving projects where work has not commenced and the operator has total control over all aspects of the installation.

EASYJoint can be used on both permeable and impermeable bases, however, as you have control over the mix of the mortar bed on which your paving will lay then you have an ideal opportunity to make sure that the whole project is permeable.

Permeable Projects

Suitable for pedestrian areas

Base Mix

To create a fully permeable project, the bedding mix & any sub-base must be appropriately constructed. An impermeable base with permeable joints is pointless.

To ensure a fully permeable project, not only must the sub-base be permeable but so must the bedding mix. A mix of 6 parts sharp sand to 1 part cement (6:1) or weaker will ensure this. A mix of this strength is perfectly adequate for pedestrian areas.

Note: Many contractors would prefer a slightly stronger mix of say 5:1, especially when working with an absorbent natural stone, to ensure adhesion of the paving material to the bedding mix. This is not a problem for EASYJoint, subject to the ground conditions being well drained – Click here for details. However, a mix of 5:1 may cause the project to become either impermeable (see below), or at least slow to drain.

For domestic driveways, please refer to the Impermeable Project below.

Concrete paving with a chamfered edge

Sometimes, concrete paving is made in moulds & has chamfered edges. In such cases, when two paving slabs are laid side by side a “V” shaped gap is formed, wider at the top than at the bottom. This gap shape can be the most challenging to work with & we recommend you carefully follow the instructions below.

Concrete paving with a chamfered edge
  1. Maintain the Width of Joint Throughout Maintain at least a 3mm gap width throughout the depth of the paving material. Never have this type of paving butted together. See photograph adjacent.
  2. Lock in the Joint An irregular "V" shaped joint means that any type of filler, EASYJoint included, will have difficulty in staying in place.
    To assist in forming a stable joint we suggest that when laying the paving you draw the tip of your trowel along the bottom of the edge of the slab you have just laid so that a small gap is formed along & under the edge of the paver. The EASYJoint will flow into the gap and, when set, will be locked into place. See diagram below.
  3. To further aid this, "point" or "strike" the joint; do not leave it textured. This assists to compress the filler & help it adhere to the base & the sides of the paving material.
  4. Do not overfill the Joint As with all types of paving, never overfill the joint. This is particularly important if the paving has a “rounded” top edge. The filler should be kept below the start of the "rounding". See diagram below.

Natural Stone

Thin Paving

The modern trend with Natural Stone paving is for it to be machined for regularity of thickness. In many cases, this will create a paver of just 22mm thick or less. If you are working with such paving, please refer to the Joint Dimensions and working with thin paving in the before you start section.

Sensitivity to marking

Even with liberal amounts of water, some types of natural stone, e.g. Granite, Black Limestone and Modak, can be very sensitive and susceptible to marking; from the natural environment, from mortar used for the base or joints or from specialist joint fillers.

To greatly diminish the possibility of marking these types of stone we strongly recommend sealing the paving with a breathable sealant, if possible before installation but certainly prior to jointing. A breathable stone sealer will provide protection both during the jointing process and afterwards. It will also allow any efflorescence (white deposits caused by natural salts) present in the base and substrate to pass up through the paving material and over time, dissipate harmlessly into the atmosphere. This is a problem that is particularly prevalent in Black Limestone and will regularly appear after installation. It is not caused by the use of EASYJoint.

Our own water-based sealants - EASYSeal SSP and EASYSeal Ultimate - are ideal for this purpose. If in doubt please contact us at info@azpects.co.uk or call us on 01473 760777.


Applying EASYJoint

Weather Conditions

When working on a permeable base, EASYJoint can be applied in virtually all weather conditions except when temperatures are freezing or are 3 degress celcious and falling. For more information on application in inclement weather, refer to the before you start section.

If you have used a bedding mix of 5:1 sand/cement, you would be advised to follow the weather guidance detailed in Impermeable Projects detailed below.

Application Method

The preferred, fastest and safest method of installing EASYJoint is to use the wet application method.

As a final check before proceeding to install EASYJoint and to ensure this is the correct method for your project, check it meets the following criteria:

  1. The site conditions are suitable – Refer to the before you start guide.
  2. Ensure you are not working in freezing conditions or in temperatures that are 3 degrees celcious and falling – Refer to the before you start guide
  3. The base is permeable
  4. When working with Natural Stone paving ensure it does not require sealing prior to installation – See Nature Stone above

If all these conditions are met, install EASYJoint using the wet application method.


Impermeable Projects

Suitable for pedestrian areas and domestic vehicular driveways

1. Base Mix

An impermeable project is when the bedding mix and even in some cases, the sub base, is constructed so as not to allow water to permeate. A bedding mix made to a 5:1 or stronger sand cement ratio will achieve this.

Such a base would be suitable for a domestic driveway and whilst it is unnecessary for a pedestrian area, some contractors prefer to work to this criterion.

Applying EASYJoint

Weather Conditions

If you were working with a permeable base, the description of EASYJoint being an "All Weather" product is true. However, because you are working on an impermeable base, which will restrict the draining of water, some weather precautions do apply.

You are strongly advised to wait for a dry spell when moderate to heavy rain is not forecast for at least 18 hours (moderate to warm temperatures) or 36 hours (colder conditions) after the application. This is to give the best chance of the water that was used in the application process being able to drain and evaporate from the joint and for the curing process to commence. If further water is added from rainfall during the curing process, there is a risk that the surface of the joint will cure through evaporation but the bottom of the joint will not, leaving a weak result.

When temperatures are freezing or are 3 degress celcious and falling, refer to the before you start section.

Application Method

When working with an impermeable base, the operator has a choice of application methods (wet application method or dry application method) and needs to select the most appropriate for the job, wait for a dry spell of at least 24-48 hours as appropriate (See specific application method below).

The paving must be protected from the oil inherent in the EASYJoint and the most common method of doing this is with water using the wet application method. However, EASYJoint requires oxygen to cure – Whilst it is wet, it will not set!

Because you are working with an impermeable base, there is a risk that any water used in the application process will evaporate from the surface of the joint allowing the top part to set hard whilst the lower part remains wet (because the water will be slow to drain). The problem is compounded if during the curing process it rains. Because the lower part of the joint is subject to a prolonged wet period with a seal being formed at the top of the joint, the curing process can not complete as the water at the bottom of the joint will not be able to escape/evaporate . This will cause the "binding" properties of the compound to become compromised.

When to use the dry application method

The dry application method would perhaps be better referred to as the "almost dry application method" because a small amount of water is still used to assist the compound being swept and falling to the bottom of the joints.

It would be appropriate to use the dry application method in the following circumstances:

  1. The site conditions are suitable – Refer to the before you start guide.
  2. Daytime temperatures are cool (even cold) and overnight temperatures may drop to 3 degrees celcious or less
  3. There is a possibility of rain within 24-48 hours of application.
