What sort of base should I put a Bonded system on?
Resin Bonded systems can be applied to a new or existing base. This could typically be an existing surface of tarmac, asphalt, concrete or other monolithic material as long as it has been cleaned and prepared.
Ensure that the base is in good condition as the finish and longevity of any system applied is dependent on the soundness of the base that it is applied to. Making sure that the surface is properly cleaned and that any loose materials and dust are removed and sealed if necessary. To make sure that the resin adheres to the base any contaminant such as oil, traffic film, algae or fungus will have to be removed with a suitable de-greaser.
Make sure that the base is level and that any damaged areas or cracks have been repaired before the resin is applied. Always make sure that the base is suitable for the traffic load it is expected to carry once the resin system is applied. Suitable bases can vary depending on the system used, it is recommended that advice from the resin supplier should be sought prior to application. Surfaces that have fewer joints and are predominately large slab areas such as tarmac or concrete should provide the best finish. Any bases that are made up of paving products such as block paving, sets or flags etc are NOT recommended for use as the base for a resin-based system as the amount of cracks or lines below the surface would ultimately lead to cracks in the resin and failure of the system due to the extreme pressure loaded onto the resin during day to day usage.
When laying a new base for the Resin Bonded system make sure it has been allowed to cure properly prior to the application of resin systems. In the case of bitumen surfaces a minimum of 28 days should be given to allow it to weather and oxidize.
For concrete, at least 7 days should be given to allow it to cure properly. It is important with any base used that the moisture levels on the surface meet an acceptable level as recommended by the resin manufacturer. In all cases, the manufacturer's advice and recommendations should be followed regarding preparation, pre-cleaning, etching or whatever is required. For any surfaces that are absorbent a primer should be used.
