General Information & Precautions If you are reading this AFTER you have used EASYJoint, it is too late! Site Conditions. The site conditions must be appropriate for use. Refer to page 1. Use Plenty of Water. It cannot be overly stressed to use plenty of water before, during and after the application of EASYJoint. Sensitive Paving Materials. Some types of natural stone, eg, Granite, Black Limestone and Sandstone, can be very sensitive and susceptible to marking from the natural environment, from mortar used for the base or joints and from specialist joint fillers. If unsure, refer to the stone supplier for advice on the sensitivity of the particular stone, for even using liberal amounts of water as demanded elsewhere in these instructions may not be enough to prevent marking. To greatly diminish the possibility of marking these types of stone, it is strongly recommended to seal the paving with a breathable sealant, preferably before installation but certainly prior to jointing. A breathable 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 through the paving material and, over time, dissipate into the atmosphere. This is a problem that is particularly prevalent in Black Limestone and Granite and will regularly appear after installation. It is not caused by the use of EASYJoint. More information on these issues can be found on the Azpects website. Water-based breathable sealants can be found in the EASYSeal Range on the Azpects website; they are ideal for this purpose. Working with Porcelain Paving. The same rules apply when working with porcelain paving tiles as with working with stone or concrete. The base on which the porcelain is laid must be able to drain.. If the base is non-permeable then EASYJoint Proor EASYGrout should be used. See the Azpects website for more information. Less water is needed when applying EASYJoint to porcelain paving as there is little risk of residue staining however, users will find that a small amount of water, added to form it into a slurry, will make it easier for the operator to fill the joints properly. When applying to porcelain, to ensure an effective joint, the operator MUSTiron the joint to further aid compaction of the compound. Note on Compaction. Whilst not a necessity, a stronger, smoother and more durable joint is achieved if the product is compacted. Compaction forces out air and water which helps the joint harden quicker. EASYJoint is Permeable. This is a positive environmental attribute but, over time, there may be changes in the appearance of the joint. Dirty surface water passing through the joint can result in discolouration. This is entirely natural; it is not a fault, and it will not impair the integrity of the product. The porous nature of the joint also allows algae and fungal growth to develop. Both of these issues can be remedied with the cautious use of a light pressure washer once a year, using a “fan” type nozzle no closer than 150mm from the surface. This will safely clean the joints of dirt and spore growth. More persistent algae/fungal growth can be tackled with an appropriate product from the EASYCare range. Do not use a pressure washer on the paving for at least 4 weeks after applying EASYJoint. EASYJoint is a joint filler and like other types of joint fillers it is not designed to hold the paving together. If the paving moves, expect to see separation between the paving units. EASYJoint has not failed. AZPECTS accepts no responsibility for such occurrences. 4
