Honestly, it might be the humidity, not the heat. Those spec sheets always talk about air temp, but if there was any moisture in the slab or the air, it can mess with the chemical cure. I've seen a "fast" sealant stay tacky for days because the concrete was sweating and nobody caught it. The product could be fine in a bone-dry lab but a total fail on a real job site.

Ugh, I don't know... sometimes I just want different hair. It's not always some deep pressure thing. Changing your look can be fun, like wearing a different outfit. My curls are a lot of work too, so calling straight hair "hard to achieve" feels off. People should just do what they want with their own hair.

My quick fixes usually end up costing me more time in the long run.
