Its a heavy duty tape that can go on internal and external drywall. Knauf do one the same.whats level line?
Does that include the sanding mate?We charge around £15 a square. That’s materials and using level line in every corner and tape and joint so. I’d say if the tape and joint good and you didn’t want level line in corners I’m guessing it’s not beaded ?? You would be about £12-£12.50m2
