Q: I am looking at re-sealing my drive, I have a few hairline cracks would I be able to fill them in using the expansion sealant? Also when I re-fill my expansion joints the 3 colours you sell look odd with the slate grey colour that I will be purchasing from you.
A: we tend to not recommend trying to seal fine hairline cracks as any material tends to 'pop' out with the expansion and contraction of the concrete over time. Once sesled they tend to be a lot less visible anyway, especially if using a colour tint with the sealer.
Q: I am about to re seal my drive with your product. Do I apply the mastic to the expansion joints before or after sealing? Thanks
A: You apply the mastic after applying the imprinted concrete sealer
Q: I have garden concrete panel fencing, it is now showing wear and tear and bare in places where it has flaked off and you can see the metal base. Can you recommend a product for repair and then sealing it. Thankyou
A: Would be best to get in touch with our technical team online or over the phone who will best be able to advise you.
Good stuff. Should have bought more the first time but now all done and looks great
