4 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 stones 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. Using liberal amounts of water as demanded elsewhere in these instructions may not be enough to prevent marking. To diminish the possibility of marking these types of stone, it is strongly recommended to seal the paving with a non film forming sealer, preferably before installation but certainly prior to jointing. A breathable sealer will provide protection before and 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. It is not caused by the use of EASYJoint. More information on these issues can be found on the Azpects website. Water-based breathable sealers can be found in the EASYSeal range on the Azpects website; they are ideal for this purpose. 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 discoloration. 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, using a “fan” type nozzle no closer than 6" from the surface. This will safely clean the joints of dirt and spore growth, and in most cases restore the joint to its original permeability. 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. Strength. The compressive strength of EASYJoint is such that it will adequately take the downward forces exerted by pedestrians and light domestic vehicles. However, if planning to use it on vehicular driveways please read the section on Residential Vehicular Driveways (page 3). Sealing. EASYJoint can be sealed but it is recommended not to apply any type of sealer over the joint for at least a month after it has set hard. Depending on the type of sealer used, EASYJoint may or may not remain porous. Applying EASYJoint Without Water. Installers are strongly advised to apply EASYJoint using the standard method as described in these instructions wherever possible. However, there are circumstances where this method may not be suitable, such as when using the compound in freezing conditions or in temperatures of 38ºF and falling. When applying without water, the risk of residue staining is higher. Refer to the Azpects website for more guidance. Footwear Caution. The soles of footwear may pick up some EASYJoint during application. Clean them before walking across dried (or drying) paving to avoid leaving “footmarks”. Do not use the same broom that was used to apply the EASYJoint to clear the surface afterwards; it will be contaminated and may leave marks.
