Which sealant for tile gaps?

Hi,

Have a few 'gaps' between surfaces, and just wanted to confirm the right product to use. First photo is indoor, and gap is not much wider that the grout lines. Second and third photos are outdoor gaps. I was considering using Sikaflex Pro, but that seems to be the wrong product the more I look into it. One of the selleys no more gap ranges? Thanks.

Hello @WL

Both Sika and Selleys are good products in regards to sealing gaps. I propose looking at the Sika 310ml White Sikaflex Pro+ Polyurethane Sealant - 310ml White. This product is designed for interior and exterior use. It is designed as both a sealant and adhesive, plus it has excellent movement and stretching properties. Selley's of course have the Selleys 430g White No More Gaps Exterior Gap Filler and the Selleys 475g No More Gaps Interior Multipurpose Gap Filler.

If you have any other questions we can help with, please let us know.
