Will this adhere to porcelain tiles?

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.

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

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.

Is the finish gloss OR matt on this product ?

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

What is the difference between the blue and red tubes?

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
