Before using EASYJoint read all of these instructions, visit www.azpects.co.uk and watch the video Pre-Installation Checks EASYJoint is designed for use on a free draining site. Before using, check the site conditions are suitable for the use of EASYJoint, which is a permeable jointing solution (see below). Site Conditions IMPORTANT: The project’s ground conditions must be free draining. If the area stays naturally wet and rarely dries out, or if there is a high water table, then EASYJoint should not be used. EASYJoint cures gradually on contact with air, so, if the paving base never or rarely dries, nor will the bottom of the joints, resulting in joint failure. If the joints cannot gain full exposure to air, sometimes the top will crust over (from evaporation) but the lower section of the joint may not cure properly. Additionally, ensure the project has a suitable "fall" to allow surface water to drain away. Base Mix For a project to be free draining, both the bedding and sub-base must be porous. To achieve this, assuming a permeable sub-base, where a mortar bedding is used it should be no stronger than 6 parts sharp sand to 1 part cement (6:1). This will ensure good drainage and is perfectly adequate for pedestrian areas. If water is retained in the joint for long periods, rather than passing through, the joint may fail. Note about use of ad-mix products. Adding products such as PVA, SBR or other additives can greatly affect the porosity of mortar and may make the paving base unsuitable when jointing with EASYJoint. Weather Conditions. When working on a free draining, permeable project, EASYJoint can be applied in virtually all weather conditions. However, in freezing conditions, or in falling temperatures below 3°C, refer to the website for guidance. If heavy or prolonged rain is forecast, ideally wait for drier conditions, as heavy rain could disturb the sand particles that make up EASYJoint before it cures hard, giving an uneven texture. Prolonged rain will also extend the curing process. See www.azpects.co.uk for more information. Suitable Paving Types. EASYJoint can be used with all paving types, subject to the minimum 3mm joint width (see section on Joint Dimensions). It is, therefore, NOTsuitable for the UK’s traditional block paving, where the joint width is typically 1-1.5mm. Some paving types need additional attention before and during the use of EASYJoint. In particular, please be aware of the information supplied elsewhere in this guide about sensitive natural stone types and paving with chamfered edges (‘V’ shaped joints). EASYJoint Colours. There are various colours to choose from. However, EASYJoint is made from naturally sourced products and shades may vary, so always select tubs with the same batch number to complete a project. The name of the colour and the colour of the lid are for identification purposes only and are not a representation of the actual colour of the contents. Colour samples are normally available from your supplier and can also been seen in our literature and on our website. To ensure the colour meets your requirements, test a small area before spreading out the whole tub. Repointing Old Paving. (Not suitable for use on chamfered sided paving). Clean out the old jointing product completely to create the correct joint size (see section on Joint Dimensions). Do not use EASYJoint if the correct and fully clean joint size cannot be obtained. Be aware of the information supplied about site conditions and the porosity of the base and ground conditions. If there is uncertainty about either of these factors, do not useEASYJoint. In such instances, EASYJoint PROmay be a viable alternative - visit the Azpects website for more information. Joint Dimensions. Minimum width: 3mm, minimum depth: 20mm. There is no maximum width but minimum depth must be achieved. When working with thin paving material, it is difficult to achieve the correct depth. In such cases, to achieve the required depth, create a channel in the base material by running the tip of a trowel around the exposed edges of each paver. Ensure that at least the minimum gap width is maintained throughout the full depth of the paving. 1
