![]() | Question: Can I use this paint as a finishing paint on a tiled balcony which is waterproof but discoloured? |
Answer: We would instead recommend the use of Sikafloor 161 as the primer and Sikafloor 420. However you need to ensure that the tiles are well bonded and not breaking up, otherwise you will need to remove them. Lightly abrade the tiles to remove the sheen and to provide a griping texture. Download the Additional System Data Sheet (MB-25) from the product page for more details. | |
![]() | Question: I am looking to paint a long outdoor concrete balcony in France. The current grey paint has been eroded by water drawing from the food in winter and hot sun in summer. The balcony goes all round the house some south and west facing in hot sun other areas east and damper. Would silks 405 be the best paint? The current finish is moth grey and looks smart in places. I would appreciate your advice kind regards |
Answer: Sikafloor 405 is ideal for balcony areas but you must read the product TDS (Technical Data Sheet) available to download from the 'DATASHEETS' tab on the product page. This goes through preparation, systems, number of coats, etc. We have also written an article on our blog on some of the most popular Sika balcony systems called Sikafloor Balcony Flooring Systems which may have some more useful information for you. | |
