Hormuz, Bab el-Mandeb and your tile adhesive (2026)
Two straits at war in 2026 squeeze construction-chemical feedstock - the binder in your tile adhesive - at source, not just freight. What moved, what did not.
Tile Grouts
Tile grouts are the thinnest and most exposed mortar in a tiled system - the joint between two tiles. They fail for reasons written into how they were mixed, when they were worked, and what moves beneath them. This cluster covers cementitious and reactive tile grouts: the standards that govern them (EN 13888, ANSI A118.6/A118.7, IS 17190), how they are formulated, and how their failures are read.
Grout classification, decoded: CG1, CG2, W, A, F
Grout classification without the mystery: what CG1, CG2, W, A, F and RG certify on the bag - and why the EU, US and Indian standards do not convert.
Grout was never waterproof - and never had to be
Tile grout is porous by design - its own standard never even tests it for waterproofing. What the W class really buys, and what keeps water out.
Why tile grout crumbles: the joint that can't cure
Crumbling, powdery grout is almost never a bad bag. The joint is the hardest place in the whole system to cure - why it happens, and a 30-second site test.
