| Pointing Preparation | It is recommended to wait at least 7-14 days before pointing. It can help to dampen natural paving before grouting to help reduce the risk of picture framing. Prior to grouting the open grout joints clean, dry and free of residues. Porous or textured tiles/slabs may require sealing before grouting with a suitable impregnating sealer. If in doubt trial an inconspicuous area to check for staining and correct colour before commencing. |
| Mixing | Mix each 25kg bag with 4.5-5.0L clean water. GPM should be mixed with the correct amount of water using a low-speed drill and mixing paddle. Mix for a minimum of 3 minutes, allow to stand for 2 minutes, then remix. To check consistency, fill the tube of pointing gun and shake, the mortar should 'hang' from the nozzle. Do not mix more product than can be used in approx. 40 minutes. Do not add more water or 'wet-up' mortar which has begun to set. |
| Application Process | GPM can be applied to joints from 5mm wide up to 150mm deep. Joint depths should ideally bee 1.5 times the width. After filling the pointing gun, place nozzle as deep as possible into the joint and inject the mortar. Fill the joint from the bottom and allow to slightly overfill the joint. Allow mortar to stiffen before removing excess and tooling as required. Any mortar remaining on the surface of the paving should be removed and washed immediately before it sets. Use of excessive water or "wash boys" to clean the paving is NOT recommended as the high amount of water can result in excessive efflorescence. To ensure colour is correct please test the product first and always use the same batch. Refer to the install/product guide for further information. |
| Cleaning Tools | Wash all tools frequently to avoid material bonding to them |
| Cleaning During Application | Always keep a clean sponge and water available for wiping off any excess or spillages from paving |
Aftercare
Can withstand a light jet wash, be careful not to get too close which could damaged the joint
