Just realized my old chalk line was costing me time on every foundation layout

I was marking a slab for a garage in Springfield last month, and my lines kept snapping back with a weak, faint mark. The reel was full of this cheap, clumpy chalk that had absorbed moisture from my truck bed. I grabbed a new Milwaukee chalk line and a fresh box of blue chalk from the supply house, and the difference was instant. The line was crisp and held tight for the whole 40-foot pull. Anyone have a favorite brand of chalk that really holds up in humid weather?

I switched to Tajima Pro chalk a few years back after a string of bad lines. Their stuff is sealed tight and the powder stays dry even in a damp basement. I get the red for concrete because it's just more visible against the gray. It costs a bit more but you're not wasting half the box.

Yeah the sealed packs are a game changer. Tbh I just keep a small silica gel packet in my chalk box too, helps a ton with moisture.

Wait hold on, you keep silica gel packets in your chalk box? That's wild dude, I never even thought of that. I always just tossed those things away without thinking twice, now I feel like I've been wasting a perfectly good hack. Does it actually keep the chalk from clumping up long term or is it more of a temporary fix? I gotta try that next time I'm working in a humid spot. My chalk always ends up getting hard and crusty after a few weeks and I just assumed that's how it goes. You might have just saved me a bunch of money on replacements.

Honestly that bit about the damp basement hits home. My old chalk would turn into a brick if I even looked at it wrong down there. Tbh paying a little more to actually use the whole thing sounds way better than constantly replacing cheap boxes.
