Blackline BL816 Black Water Proof Chalk Line Compound - 8 oz Refill Bottle

I got this after watching a video where it was recommended by the Venable Larry Hahn and he sure was right when he said “it’s just a damn good chalk ”. When we’ve been marking a lot with it our hands turn dark and dingy looking till we can wash up with soap and water but I’ve been blown away how I can come back to an accurate line a week later after a couple downpours and it’s right where I left it. Highly recommended… It did clog up an old Stanley chalk line that was towards the end of its life but it’s been flawless in the Tajima

Good stuff. Wear gloves when using if you don’t want black fingers

works better than local stuff

This product is worth its weight in gold! Absolutely the best chalk product I’ve used so far! 100% worth it!

Seems good, just sometime you want to disappear easily. Sometimes needs to stay under all weather. Discovered, do not use on a wet surface...that made a mess

The bottle was half full and the bottle was open.

I purchased this product because it was highly recommend however, this product suggest the bottle you will receive is full (like pictured on Amazon). I have not had a chance to use the product but did notice the half-empty container. Yes it’s true that it measures up to 8 ounces. My container of Blackline appears to be a 16 out bottle or half empty.

Handles great, not dusty. Stays in place. Easy to see. Doesn't clump.
