ProJoint V75-WT 27Kg Joint Filler- Pallet Deals and Bulk Buy – Two-Part Epoxy Resin Mortar System Suitable For Vehicles Up To 7.5 Tonnes

ProJoint V75-WT extended information

Coverage:

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 two-part 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 of 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.

Due to the high epoxy resin content ProJoint V75-WT will 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; weathering and foot traffic will accelerate its disappearance.  For extra porous paving, or to minimise any effect use ProJoint V35-UV.

Please note: when using wet cast concrete paving with tapered edges we recommend the following procedure to minimise the risk of any type of jointing compound/cement ‘lifting’ during or after curing due to the base of the joint being narrower than the top.

To ensure the ProJointTM jointing compounds can lock’ under the paving and achieve the best possible joint and reduce the possibility of the compound ‘lifting’ during or after curing:

1. Ensure the base of each paving slab is a minimum distance of 3mm from other slabs and create a small space under the joint area of each slab.
2. Ensure the jointing compound fills the joint to just below the upper surface of the paving slabs. (Pointing/striking with a trowelliron will help adhesion to the sides of the paving further.)

Preparation

1. 1. Ensure the surface of the paving is clean prior to application** and the joints are cleaned out to a minimum depth of 25mm for 7.5t traffic loading, and a minimum joint width of 5mm. Paving should be firmly bedded and stable prior to filling joints and laid on bedding material suitable for the intended traffic loading. **Care should be taken to ensure no soil or dirt is left or walked onto the surface of the paving during the application process as this may get trapped in the resin once cured.
   2. Liberally wet the paving prior to mixing the product, allowing the water to soak into the surface.
   3. ProJoint V75-WT should be mixed in a suitably sized bucket using a plasterers’ whisk. When wearing appropriate PPE, add the sand to a mixing vessel, pour the resin and hardener into the sand together and begin mixing.
   4. Mix for around two minutes until thoroughly mixed.
   5. Add 3 litres of water to the mix (equivalent to 2 x resin containers and 1 x hardener container).
   6. Mix for a further three minutes until the mix becomes a free flowing slurry. Ensure that the paving is still wet and the surface temperature is between 3oC and 25oC. Do not allow the paving to dry out during application – care should be taken when using the product on dark paving in direct sunlight due to high surface temperatures.
   7. Empty the mix directly onto the paving.
   8. Move the mix using a squeegee over the total area – allowing the empty joints to fill completely.
   9. Leave for 10 to 15 minutes.
   10. Use a wet medium soft brush at 45o to joints to sweep off the excess sand, leaving the paving clean.
   11. 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. Do not add additional water to the surface at this time. 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.

PLEASE NOTE: ProJoint V75-WT is not designed for porcelain paving – if you are planning on using porcelain paving, please refer to our ProJoint Porcelain Primer and ProJoint Porcelain Grout.

ProJoint 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 therefore weathering and foot traffic will accelerate its disappearance. For extra porous paving, or to minimise any effect use ProJoint Fusion or ProJoint V35-UV.

This product can be used in light rain but prolonged and heavy rain will delay the curing process and increase the risk of fluid damage so we recommend that the jointed area is covered if there is a chance of rain. Please make sure that any protective cover does not come into contact with the fresh joints; air circulation over the 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. Please note that cold temperatures can delay the curing time.
