Q: How long before I can drive over a silicone mastic joint
A: You should able to drive over the surface after 24 hours.
Q: Do I need to apply a primer to the expansion gap (after cleaning and sealing) to ensure the mastic will adhere, or can I just apply the mastic straight into the expansion gap after the sealing has been applied and dried?
A: No, you do not need to apply a primer to the expansion joint to ensure the mastic adheres OK. The mastic can be applied to the expansion joint after the imprinted concrete sealer has dried.
Q: I have a neutral concrete driveway with expansion joints. A magpie is pulling out the sealant between the expansion joints. What do I need to replace the missing sealant please? Internet states a flexible concrete caulk. What do you recommend? Many Thanks.
A: We would recommend using the Silicone Sealant (For Concrete Joints) to replace the sealant being pulled out by the birds.
