Review: Easy to use and looks good - I recently used this to silicone the expanding joints on a fireplace, needing something with reasonable heat resistance. Was a bit tricky to apply as the instructions state NOT to fill the joints, but after some initial wobbles getting the hang of it, it turned out pretty well. Not yet into fire lighting season (the area has since had a firebox returned to it) but hopefully that everything will hold up well.
Review: Very good - Best price, nice colour

## Questions & Answers

**Q: Will this adhere to porcelain tiles?**
A: Yes it will, provided that the surface is clean and dry. It has done a very good job as a sealing bead between our bath and washbasin and loo and ceramic wall and floor tiles. It has also proved durable over the last two years.

**Q: Clean-up after with what? water, no! turps sub? forget it! meths? just about. what is recommended?**
A: Hello,

A good product for cleaning up silicone is WD-40. If it is dried then a sealant softener may be more effective.

I hope this helps.

**Q: Is the finish gloss OR matt on this product ?**
A: Unfortunately you can not get a gloss or matt finish in silicone, how ever it will have a shine to it due to the acetoxy in the product preventing mould

**Q: What is the difference between the blue and red tubes?**
A: HI there. The red tube is just the updated colour of the label. no difference in the product inside the tubes. Regards The Tile Experience

### ⭐⭐⭐⭐⭐ Very good
*by N***A on 17 March 2025*

Best price, nice colour

### ⭐⭐⭐⭐⭐ An exact match to the Mapei ultracolour plus grout
*by M***L on 30 September 2020*

Mapei Mapesil medium grey sealant was a perfect match to the same colour of Mapei ultracolour plus grout. Excellent product - was easy to apply and smooth off (using a 10% fairy liquid/90% water spritz). As an aside, note that the Unibond "special materials" grey sealant is NOT a good colour match to this Mapei product although the tube colour indicates that it is (I purchased Unibond when I ran out of the Mapesil product as it was not available locally. The Unibond colour dries much lighter than the colour indicated on it's tube).
