Review: High-Spec stuff - Perfect for repairing holes in uPVC doors etc, and also for other sealing and caulking jobs around the home. It bonds to anything apart from your fingers; it cures quickly, even underwater, so it'll probably seal your yacht too; you can paint over it; it's anti-mould, anti-fungal; flexible, but not too flexible. Brilliant white in colour, both when squeezed and when set. Doesn't expand as much as I thought it would, so you may need a top-up application. Remember to wear gloves when applying.
Review: The Best Multi Use Mastic on the Matket - I have been using Tec 7 for 4 years. It is a solvent free mastic and adhesive and can be used to bond most items. It is a sealant for all sorts of bathroom areas and is excellent to seal around window frames, coving and more. And it never cracks open. It is more expensive than ordinary mastic but you do the job once and it last! Buy it!

## Questions & Answers

**Q: Does anyone know if Tec7 is heat resistant?**
A: no its not heat resistant

**Q: I used tec7 when fitting handrails on a grp boat. How do I break the tec7 hold?**
A: A very thin sharp blade long enough to get between the the rail and the GRP or perhaps a cheesewire.  A strong pencil eraser and peeling might get the remaining residue off.  Strong solvents might weaken the resin gelcoat but a paintwork cutting compound may help, check it on a test area first.
