When to use each format
Block: pressed chalk you crush inside your chalk bag. It is the cheapest per gram and you choose how chunky it gets.
Loose: ready to use and covers your hand fast. It is messier and kicks up more dust. It is the classic choice for outdoor bouldering.
Ball: a fine mesh sock filled with chalk. Squeeze it for a thin coat without a dust cloud. Ideal for the gym.
Liquid: chalk dissolved in alcohol. You apply it before you start and it leaves a layer that lasts longer than loose chalk.
Bulk bag: for people who climb several days a week. Much cheaper per kilo and good for refilling bags and balls.
Liquid chalk as a base layer
The most common trick is to apply liquid before warming up, let it dry and touch up with loose chalk during the session. The liquid base lasts and the loose chalk just tops it up.
Simond Liquid Chalk V2 contains 72.9% isopropanol plus rosin for extra grip, and dries in about 22 seconds according to Decathlon. Alcohol dries your skin: moisturize after climbing.
Gyms that require a ball or liquid
Many indoor gyms ask for chalk balls or liquid chalk to reduce airborne dust, which dirties holds and filters and bothers people with asthma. Ask before bringing loose chalk.
If your gym requires it, a ball inside your chalk bag, or liquid with a ball touch-up, is the easiest combo.
Magnesium carbonate and additives
Climbing chalk is magnesium carbonate. It absorbs sweat and dries the skin. Simond's 1 kg bag, for example, lists 99.7% magnesium carbonate and 0.3% calcium carbonate.
Some makers add drying agents or, in liquid chalk, rosin. Friction Labs markets its chalk as high purity with no fillers. If your skin is very dry, a pure, fine chalk usually feels better.

Frequently asked questions
Is liquid chalk or loose chalk better?
They work together. Liquid is a long-lasting base and loose chalk is for touch-ups during the session. If you can only pick one, go liquid or ball at a gym with chalk rules and loose outdoors.
Why do some climbing gyms ban loose chalk?
Because of airborne dust: it dirties holds and ventilation and bothers people with asthma. That is why many require chalk balls or liquid chalk.
Is climbing chalk bad for your skin?
It dries your skin, which is exactly its job. Wash your hands after climbing and moisturize. Liquid chalk dries more because of the alcohol.
Can I use climbing chalk at the gym?
Yes. It is the same magnesium carbonate used in weightlifting, CrossFit and calisthenics. Check first whether your gym allows it.
