Q: How much coverage do you get per tube . Thank you
A: If you are just 'capping off' expansion joints, created with an angle grinder? One tube should cover approx 7 linear metres. Hope that helps.
Q: Ideally to what depth should this be applied
A: The concrete is normally 4" inches deep. There is no point try to fill the joint, so just 'cap it off' using a minimum ammount of mastic. For expansion joints cut with an angle grinder, 1 tube should cover approx 7 linear metres. Hope that helps
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.
Good stuff. Should have bought more the first time but now all done and looks great
Does exactly what it is supposed do and very easy to use - even forr a 76 year old grandma!
