## Questions & Answers

**Q: Can I paint over this stuff with outdoor masonry paint? if so, what time period should i let the water sealant dry for before i apply the paint?**
A: Yes you can paint over it with this sort of paint the seal will just act as an extra weather protector.  Probably say 24/48 hours to put paint over it to make sure depending on weather conditions.

**Q: Can this be applied with a spray gun or does it have to be applied with a brush or a roller?**
A: Used this on the rear brick elevation of the house last summer, I don't think you would get an effective cover using a spray gun. The product is very "thin", I would have thought it would run whereas a brush gives the opportunity to brush it into the brick facing and mortar joints.

**Q: If I use it to seal brick work on an internal wall will it still be able to provide a key for plastering over it?**
A: Rest Express - Wood Finishing Products:  It would have quite a strong smell so it would not be recommended for internal use.  I would also think think it would inhibit the adhesion of the plaster.

**Q: Can Thompson seal be aplied ontop of masonry paint**
A: Possibly but why? Would'nt it be more effective to add an additional coat of masonry paint to your existing surface, it would probably be more effective.
