## Questions & Answers

**Q: Hi Does anyone know how many m2 this would cover ?**
A: hi I had a 4 ltr tin and I gave a 3mx2m flat roof two coats and still had 1.50ltrs left. consertrated on joints ,good  product.

**Q: Is this definitely waterproof? When applying it appears to be like regular paint and washes off skin and brushes as normal with water...?**
A: Have used Thompsons  10 year Roof Seal on many occasions over the years and it is a very good  roof waterproof seal if used in accordance with their instructions.
It will not for instance last  for the guarantee period if there is any standing water or 'poncing' on the roof.
As it is water based the paint does give the impression that it is a standard type paint but when fully dry it a a good roof seal.

**Q: Do i paint this straight onto wood or do i need to fit felt first?**
A: If this is a new roof it must have felt fitted. If the felt is fitted correctly by a professional you will not need to use roof seal, as all the joints will be sealed. You will only need to use a roof seal when the roof starts to wear and show signs of ageing. This is then painted onto the felt to stop leaks.

**Q: How soon can I paint my felt cabin roof with Thompson’s after applying spear and Jackson algie spray**
A: I did not use Algiers spray
But the paint was fine no problems
