Tech Tips: Mixing Hardener with Body Fillers and Glazes

[@josephmyers1492]

FINALY a true way to determine the proper ratio. Thanks, you for your precision.

[@edwardalamo2507]

A scale is expensive and not needed

[@normgraham6658]

I am using waaaaaaaaay too much hardener.... great video

[@nc240coupe]

Being experienced and using 3m filler and glaze for the most part everyday for the last 13 years, I take into consideration the temps, but most importantly the size of the spread and the difficulty when I mix filler which is essentially no more than what he shows in this video, if anything I use a little less on big spreads to give myself plenty of working time but mix it thoroughly, not “stir” is, press out air pockets, and tight, thin spreads, I get complemented a lot on how clean my spreads are, and painters love them because they rarely have pinholes

[@ayame5887]

I have to give you Sir the thumbs up... Because everything that you are explaining in this video is very reasonable and understandable and you also touch base on every point OMG I have never in my life heard anything like this great job.

[@marksearcy9708]

Excellent, the % was what I wanted to know.

[@3MCollision]

Hi Mark, we typically recommend 1.5-3% hardener to filler, with 2% (or 1:50) being the most common mix ratio.

[@edwardalamo2507]

A measuring scope for filler please,then 3/4 to 1inch hardener

[@ayame5887]

And just for the record I now understand the right ratio of using the hardner.

[@ali-sleimanchehade6129]

Thank you for that video! Love it! Helps a lot 🙏

The chemical reaction is exothermic, a process by which heat is created. I don’t live with math on the tip of my mind, unless my wife has the credit card. But using scales, 100 grams with 2 grams of hardener is 50 to 1. In this example, 50 grams with 1 gram of hardener is 2%. I do like the idea of placing the hardener next to the filler product as you have other things going on. A co-worker needs help installing a part, your name is called over the loud speaker as you have a call on line 3, or those times when nature calls, do to 4 cups of coffee! It all matters for a long lasting repair done right. Nice reminder of a basic function we take for granted! Thanks.

[@timbartley5678]

On the 3 m sheets would be nice to see preprint colored coater on bondo to harder 3 to 4 different size like 4 6 or 8 inch then to the side harder lines

[@dyingforpie6879]

Excellent video love 3m ( and not just because im from Minnesota 😉 ) i love the scale ideaand im betting alot of watchers are realizing they use way too much hardener- ive seen guys need 3 tubes per gallon - that scale will help . Thanks for the help.

[@MrFireman164]

Excellent!!

[@georgelusaka9646]

Awesome information

[@fabe202]

Great presentation!!!

[@santanagarza624]

Wow, I really need to rethink accelerence and hardener. My experience lies mostly in concrete but now I'm going to be less inept when it comes to adding calcium chloride, the correlation is crazy but now that I'm doing more Home Remodeling and repair this video will really help

[@douglasgallardojr4759]

This is a great informative video.

[@kennethugochukwu-cv5fi]

Please any tip on cream hardener production?. Any video link will greatly help me in this project

[@timbartley5678]

One other thing gussen weight the thickness on where you might be 1/2 filler on the board with a 4 inch puddle next time u might be thinker or thiner so that could be a difference in hardner

[@niazalsomai3526]

thank you for the tip

[@Mark-gg6iy]

@5:22 "I like to dispense a bit of hardner at the beginning onto a paper towel" I understand why but if you have kneaded the tube properly why waste this? Using it from a paper towel is more difficult than need be. Apply it to cardboard that way if it's not watery you can scoop & use. Waste not want not. Good video, thank-you.

[@douglasgallardojr4759]

The stuff on the paper towel isn't used - it's thrown away. Sometimes even after you knead the hardener some liquid stays in the hard plastic where the cap threads are and doesn't get mixed. There's not much to be done to avoid that, except maybe to mix your hardener before you add it to the filler.

[@garybrady7245]

Wouldn't 2 percent be........2 percent instead of 7/8 of a inch lol like you put you the amount of filler you think you'll need and weigh it and then multiply that by .02 that will tell you how much hardener you need for your particular pile example say you have 32 grams of filler you would need 0.64 gram of hardener. 32 times .02 is 0.64. Would that be correct?

[@jasirsofi3116]

Can we buy hardener tube seperately if finished ?

[@edwardalamo2507]

Why can't there be a measuring scope for accuracy

[@JudoKnowles]

I think you're better off shooting for 2% hardener at all Temps. It'll harden from what I've seen and heard but it may take longer if it's real cold.

[@timbartley5678]

Trouble i gauge the thickness to amount of harder makes a big difference on weight 50 to 1

[@evracer]

I know this isn't exactly a rocket science thing....but you would think with the total brain power at 3M and all the container technology available.....that there would be an easier way to get body filler onto a board from a can and properly dose hardener in 2021.

[@wildst1]

look at their Dynamic Mixing System, its a pneumatic gun that mixes the perfect amount of Part A & B in the nozzle and you can shoot it onto your board without having to mix it, also eliminates air bubbles completely

[@scoobyg2396]

2% by weight, why can't they just put that on the package along with their other instructions? Tare a scale with a plastic cutting board on it, 50 grams putty, 1 gram hardener, seems easy enough to do each time.

[@xtreamcj3547]

Right… check out my comment to 3m about there mixing sheets and let me know if you think it’s a good idea.

[@edwardalamo2507]

Needed like a ice cream scope then the bead

[@dausspraydausspray1138]

So great, i share yup..

[@mvadu]

Why can't you just print that 2% by weight on the packaging.. Why write in terms of length of a cylinder for goopy thing!!

[@douglasibarra4325]

Now I am clear how the putty is worked.

[@Ivanivan-zl3re]

Hi, my name is) i've been liked your type of mixing, you, the most of thing been right, but, can me ask you e few questions? Wonna be teachted

[@3MCollision]

Certainly! Please inform us of how we can be of assistance.

[@raminnajibi8343]

👍 🏎

[@boscomairena]

👍

[@edwardalamo2507]

Most common size given is golf ball size this is over

[@tedanoch]

I like this guy don’t say i’m a application Engineer

[@rickshaw6198]

When I was a body man, I told people I was a collision correction technician.

[@rickshaw6198]

I knead my hardener like roses knead rain.

[@douglasgallardojr4759]

That's so deep I need a ladder.

[@mra2957]

Great video drop the awful music…
