## Questions & Answers

**Q: Can you paint straight onto the slurry?**
A: Hi, this can be overpainted however a period of approximately 6 months is required before doing so.

**Q: Is this product breathable**
A: Breathable, in which way?? This is a waterproofing product, unlike lime mortar , and it does what it says on packet. I used it on wet dripping brickwork apply two coats and it stopped the water completely

**Q: Can the Sika products be used on a painted brick wall?**
A: Hi. Unfortunately the paint would need to be removed.

**Q: How should be the texture ? Hard or more liquid?**
A: The product should be a uniform lump free slurry, too liquid and it will slump from the wall

Sika is one of the construction industrys go to manufacturer. I used it as troweled on to a retaining wall to prevent moisture passage through to surface. It can also be applied by a brush as if painting to achieve the same result.
