Pavetuf Jointing Compound Precautions

• Amongst the wide selection of paving available some natural stone materials can be particularly susceptible to staining. These include Sandstone, Limestone, Polished Stone and other porous grades. If you follow the recommended instructions on how to use Pavetuf Jointing Compound, this will reduce the potential for staining to occur.

• Pavetuf Jointing Compound, like most external materials, will age with time due to natural weathering and site exposure conditions. A natural discolouration over time can, therefore, be expected depending on the site conditions, weathering, constant drainage of dirty rainwater and the level of cleaning maintenance offered to the paved area.

• Pavetuf Jointing Compound is manufactured from natural aggregate materials, therefore, it should always be attempted to use the product from the same batch and manufacturing date or those in close proximity to get the best colour consistency.

• Always ensure joints are filled to their full depth to provide good solid grouting. Poorly filled or bridged joints will result in failed installations.

Preparation

Before starting please ensure that the area to be jointed can be drained of water and that the mortar bed on which the paving site needs to be a porous mix of sand and cement. Pavetuf Jointing Compound is suitable for use with most paving types, apart from block paving, however, some paving can be prone to staining. Before applying, test a small area first to ensure your paving does not discolour. For more information on preparing your paving for Pavetuf Jointing Compound, please visit Pavetuf.co.uk.

7 Easy Steps to Great-Looking Paving

1. Thoroughly pre-soak the area before application. The more water used the better the result.
2. Pour Pavetuf Jointing Compound evenly across your newly laid paving. Top Tip: To help stop staining thoroughly soak the Compound in the tub before putting on the paving.
3. Using a stiff broom, brush the compound into the joints ensuring they are completely filled.
4. Ensure that the surface of the paving and the compound are kept wet during application.
5. Repeat step 3 until all joints have been filled.
6. Top up any joints that haven't been filled properly and wash off the excess Compound from the surface using a watering can or hosepipe with low pressure.
7. As the application involves water it needs to be applied in temperatures of 4 degrees and above.

Top Tips:

• The more water added, the easier it is to move the Compound and fill the joints.

• Why not add water to the tub, along with the dry Compound before pouring the compound onto the paving?

• If you are using a Compound from a tub that has been opened previously and soaked in water to preserve it, when you come to use this with new tubs of jointing Compound, you should mix the open tub with a new tub before application to avoid colour batching.

Important: Please note that staining can occur on the paving, especially near the joints, if it is not kept soaking wet throughout the application process, and if any surplus Jointing Compound is not removed from the surface of the paving.

Curing

Curing in warm dry conditions will take approximately 18-24 hours. In cooler weather curing can take up to 72 hours. Do not allow Pavetuf Compound to dry on the surface of the paving. We recommend you then seal your paved area with a Pavetuf sealer.

Storage

Any unused product can be kept in the tub just add sufficient water to cover the surface of the remaining product. Store in a cool, dry and frost-free area at temperatures between 5⁰c and 30⁰c. Pour off excess water before reuse. Be sure to use within 2 years of the date shown on the tub.

Coverage

A 15kg bucket will cover approx. 7m² of paving (based on 450x450mm slabs with 25x8mm joint width). A Natural Paving 600 Series 15.25m² Project Pack will require approx. 2 tubs of Pavetuf Jointing Compound.
