tuffbond (tub) - Priming Mortar

tuffbond is a bonding and priming mortar used to enhance the adhesion bond between the paving units and bedding mortar and where present, between the bedding mortar and supporting concrete structure.  

For ease of use, tuffbond has been packaged in pre-measured sachets contained in a reusable, recyclable tub. With individual sachets only the required amount of tuffbond is used and wastage is minimised.

Key Features 

• Creates the essential adhesion bond between bedding and the paving element
• For small-scale paved areas in sandstone, granite, concrete and porcelain paving units
• A 2–3 mm thick coat of tuffbond enhances adhesion by 100%
• Polymer and resin free
• Provides full BS 7533:101 compliance used in conjunction with tuffbed 2-pack and tufftop Utility mortars

1. Prepare equipment
2. Wash underside of paving units
3. Add 1 L of clean water per sachet to tub
4. Add sachet to tub and mix
5. Brush apply 2-3 mm thick coat to the paving unit
