Similar to ProJoint™ Fusion™, ProJoint™ MAX offers a quick and easy solution to filling joints between paving slabs and setts BUT in areas of vehicular access. Suitable for natural stone and concrete paving, ProJoint™ MAX™ is a high strength 2-part epoxy paving grout and is very simple to use.
Resin and sand is supplied ready-mixed within the tub and only requires the addition of the enclosed hardener to activate the chemical cure.
ProJoint™ MAX™ is available in three colours – neutral (buff), mid grey and black – it delivers a weed free, frost resistant joint which resists pressure washing.
• Part mixed components for fast application, all supplied within its own mixing tub
• Suitable for natural stone and concrete paving, slabs or setts
• Ideal for pedestrian and vehicular areas (up to 3.5 tonnes)
• Professional results: no mess and no returning for cleaning
• Self compacting and suitable for joint widths from 5mm upwards
• Weed, pressure washer and frost resistant
Ensure the joints are cleaned out to a minimum depth of 25mm for 3.5t traffic loading, and a minimum joint width of 5mm. Paving must be firmly bedded and stable prior to filling joints and laid on bedding material suitable for the intended traffic loading. Liberally wet the paving prior to mixing allowing the water to soak into the surface. ProJoint™ MAX™ is designed to be mixed in its tub using a plasterers’ whisk. When wearing appropriate PPE, remove the bottle of hardener from the tub contained within a sealed bag. Open carefully and empty the hardener into the resin/sand mix. Using a plasterers’ whisk mix for 3 minutes until the mix becomes a free flowing slurry.
Ensure that the paving is still wet and the surface temperature is between 0°C and 25°C. Do not allow the paving to dry out during application and care should be taken when using the product on dark paving due to high surface temperatures. Empty the mix directly onto the paving and move the mix using a squeegee over the total area, allowing the empty joints to fill completely. After 10 to 15 minutes use a medium soft brush at 45° to joints and sweep off the excess sand leaving the paving clean. It is particularly important to sweep the paving clean before the product cures to ensure any remaining residue does not set on the paving surface. The fluid nature of the mortar means that no further compaction of the joint is required. To achieve a traditional finish, a trowel or iron can be used if necessary once the mortar has begun to cure. Increased water tolerance means that the product can be used in light rain but does need protecting from prolonged and heavy rain as this will delay the cure and could cause fluid damage. Make sure that any protective cover does not come into contact with the fresh joints; air circulation over joints is required during curing time. Cure times are dependant on temperature and humidity but as a guide can accept foot traffic after 12 hours at 20oC and vehicle traffic after 24 hours at 20oC.
ProJoint™ MAX is not recommended for porcelain – please refer to ProJoint™ Porcelain™ products. ProJoint™ MAX™ may highlight and enhance the natural surface colours and textures of the paving – this sheen can be especially noticeable on grey paving, including granite, so a test area is advised before use. It is important to spread the mix across the total paving area to ensure the potential effect is uniform. Please note that this is a temporary effect and weathering and foot traffic accelerate its disappearance. For extra porous paving or to minimise any effect use Fusion™ or V35-UV™.
