Pro-Joint™ V75-WT™ was used on reclaimed French cobbles

A client who was importing thousands of reclaimed ancient cobbles from France to be used on a driveway area of approximately 300m2 chose Nexus ProJoint products for his project.

He had been recommended to point the attractive 140x190mm cobbles with ProJoint V75-WT, so the technical team worked with him to ensure the best possible results were achieved.

ProJoint V75-WT is a specialist solution to filling joints between paving slabs and setts, suitable for natural stone and concrete paving on pedestrian and vehicular areas with medium to heavy vehicle loads up to 7.5 tonnes.

The epoxy resin system is easily mixed and quickly applied as a slurry to dampened paving. It has increased water tolerance to give the great advantage enabling use in damp weather and light rain.

Its high performance means that it is used widely for domestic and commercial projects where medium traffic loading is required and when laid in times of inclement weather.

• Two-part resin-based mortar system, cement free
• Medium to heavy traffic loads up to 7.5 tonnes, ideal for driveways and high traffic areas
• Fast application
• Easy: No more bending or kneeling and much less effort
• Applied to wet surfaces plus increased water tolerance for use in light rain
• Self compacting and suitable for joint widths from 5mm upwards
• Weed, pressure washer and frost resistant
• Colours available: Neutral (buff), Mid-Grey and Black
• Professional results: no mess, and no returning for cleaning

Preparation is simple

Ensure the joints are cleaned out to a minimum depth of 25mm for 7.5t 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. V75-WT™ should be mixed by using a plasterers’ whisk. Add the sand to a mixing vessel and when wearing appropriate PPE, pour the resin and hardener together and begin mixing. Mix for around two minutes until thoroughly mixed and then add 3 litres of water to the mix (equivalent to 2 of the resin containers). Mix for a further three minutes until the mix becomes a free-flowing slurry.

Application

Ensure that the paving is still wet and 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. A trowel or iron can be used if necessary, once the mortar has begun to cure to achieve a traditional finish. 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 dependent on temperature and humidity but as a guide can accept foot traffic after 12 hours and vehicle traffic after 24 hours.

ProJoint™ V75-WT is not recommended for porcelain – please refer to ProJoint™Porcelain™ products. V75-WT™ 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™.
