Homemade bondo hardener

By | 07.10.2020

Best Answer 3 years ago. I realize this question is 7 years old but just wanted to add this for those who might see it in the future. I've had respectable results making my own "glazing putty" using talc as the thickener. Purists might scoff at this idea, but it does seem to work and I've used it under some "show quality" paint jobs. I use this as as step between the base coat of bondo and the next coat of sandable fill primer.

I find that fill primer is too thin to fill all the imperfections and bondo is too thick and difficult to sand to use as a finish coat. I mix the talc with acrylic primer if I'm going to be spraying acrylic on top or with enamel primer if I'm going to be spraying enamel.

Have not tried it with lacquer Basic rule of thumb, mix the talk with whatever type of paint you will be spraying over the top of it. I generally mix in a ration of 3 parts talc to 4 parts paint primer. But the more talc, the thicker of filler. I apply the paint with a brush using the "tipping" method. I've also had some luck applying with a brush and then swiping the surface with the edge of a plastic credit card or similar material.

If mixing the talc with enamel, be sure to allow sufficient time to dry before attempting to sand. Minimum of 24 hours and 48 is even better. Otherwise you'll make a mess of things and clog up your sandpaper quite quickly. Two part mixed with hardener acrylics will dry much faster and you may even need to use a retarder to prevent it from setting up too quickly.

Might take some trial and error to get just the right consistency that will work for you. Unflavored jello and acetone nail polish remover I think, might make super glue instead though Good luck.

Not really Bondo is a polyester resin with filler. Plus, getting the right texture is a lot of trial and error.The bottom of each shutter had taken on water somehow and was rotting. We had our house painted a few years ago, and the painters used it to repair some damage to the columns around our front porch.

It held up well. So, why not use it again? Plus, it dries so fast, it makes the repair work so much faster than normal wood filler. Make sure to always read the directions for any products or tools you use while building. Read the full disclaimer here. Start by cleaning and prepping the surface for Bondo. This can be done in basically 2 ways. One is removing all the soft and rotten wood with chisels, utility knives, screwdrivers, or whatever you have on hand.

Two is, removing just any mold, then hardening the rotten, soft wood with Bondo Wood Hardenerbefore applying the Bondo Putty. You may want to replace large sections with wood, to create a good base and scaffold for the Bondo to stick too. One of my shutters lost so much wood, that I replaced the bottom with new wood. Then filled in between the old and new with the Bondo. Once the surface is solid, hard wood and clean, you can apply the filler.

Mix just the amount you can use in about 5 minutes. Follow the directions on the Bondo. You can see how I mix mine in the video. When using bondo to repair wood rot, always wear gloves and work in a well-ventilated area.

Using Bondo to Repair Wood Rot or Damaged Wood

The fumes are quite strong and even flammable. Mix the bondo, then apply it to the area. Spread it around with the spreaders. Try to get it as smooth as possible and filled over the level you need it at.

Be sure to wear a mask, while sanding! Let harden for 30 minutes, then sand smooth with your sander. I used grit to start, to make quick work of the sanding. You can decide if you need to add more Bondo. I tend to just use normal wood filler on shallow dings and divets. Once, the wood is smoothed and sanded to a medium grit. Or, you can sand to a fine grit and stain or seal with an exterior-grade product. I do not recommend patching large areas that will be stained.

It is very hard to match the filler to the wood and will likely look patched. But, smaller areas are less obvious and may work fine. And, be sure to use the Bondo wood filler, if you are hoping to stain the wood. Looking for another Easy Home Maintenance Project?

And what's the right ratio to add of the hardner? Yes, it will harden eventually, but if you get tired of witing, just scape it off and put better catalyzed bondo on it. You should have a nice pink color, roughly the color of the plastic spreader. You should lessen the hardner for large batched, or warm temperatures.

My mix is gray from the can - With a blue tube of hardening liquid You generally mix it until it has a consistent color - normally kind of a salmon colored pink.

I haven't seen the blue. It will start to "rubberize" pretty quick and it does get warm. Normally it's pretty hard and good for sanding within minutes. As for it being old - does it still smell really bad, kind of a petroleum smell? If so, it's probably ok.I've been filling holes in the foot-well of my car unseen when covered by carpetswith mesh, hardener and filler, to stop the rain entering.

However, I've run out of hardener, so just carried on with the filler. I know it won't really solidify, but wondered if I can add something to the top surface to make it so - putty or 'Polyfiller' maybe?

Ultimately that filler not being primed or sealed afterwards is going to be counterproductive to what you're trying to accomplish. Filler even catalized use with hardener will absorb moisture and break down.

Especially with the filler you applied without the hardener. Not to mention these holes you're plugging up without corrosion protection is a sure path to problems. These holes need to be welded up. Acid wash or some kind of e-coat to prevent rust and breakdown.

In anycase the method you're using now is going to cost you a whole lot more later on. You must use hardener. The material is a two paste composite. Neither is good without the other. Like epoxy resin of which it is a type You need paste A and Paste B for it to work.

It may harden somewhat, but will not be strong. You can buy hardener separate from the filler at an auto supply store. Any advice much appreciated. Answer Save. Favourite answer.

I know I'm gonna sound like a dumbass with this, it's not my first time with filler, just first time with this issue. Using some PPG lightweight filler. For some reason it won't harden for anything. I put on the first batch, with hardener waited and 2 days later it wasn't a bit hard. Scraped it all off, mixed up another batch with considerably more hardener, now it's been a day and it's "cheese grater" hard.

The can may have frozen a while back out in my garage, but is surely thawed now, was also well mixed before usage this time. Hardener was kneaded and warmed before being added to the mix. Any ideas WTF is going on here? Getting tired of scraping the stuff off.

How Can I Make Car Body Filler Solidify Without Hardener?

I wanna get on with this project Gearhead GraphicsDec 16, As you stated, Bondo does not harden quickly in the cold but I would think 2 days is plenty. Maybe ya got a bad batch or its old or the freeze did it in. Big TDec 16, I would go get a new tube of hardener and see if that works. If its cold, it may never harden. Freezing is no good, get another can and hardner. Also heat lamp the spot if it's really cold.

If its cold it won't harden correctly. If it was mine i would throw it out and get more. I would hate to have it fail later. Louie S. I thought it was a chemical harden not a climate harden not sure of the technical term if its chemical it shouldnt matter what the temp is?

Have you tried mixing in a little Viagra? Toby DenhamDec 16, See there, love the hamb, i learned something today. Curing time is directly related to the ambient temperature of the working environment. They don't print that on the can to use ink, they know what works. Did you stir the filler in the container? Freezing may have separated the good stuff and it is in the bottom.If you create a new prediction using a logistic regression, its coefficients will be used.

You can also list all of your predictions. You can use curl to customize new predictions. It is possible to create a prediction using the filtered decision tree model by specifying filter parameters in the query string of the request parameters. Two useful parameters are support and value, as described in the Filtering a Model section.

Once a prediction has been successfully created it will have the following properties.

This is the date and time in which the prediction was created with microsecond precision. Each entry includes the column number in original source, the name of the field, the type of the field, and the specific datatype. Not available for ensembles with boosted trees.

Even if this an array the current version of BigML. A string if the task is classification, a number if the task is regression prediction filterable, sortable Object A dictionary keyed with the objective field to get the prediction output for the model, ensemble, or logistic regression.

The prediction object includes: confidence: the confidence or expected error for the prediction. In a future version, you will be able to share predictions with other co-workers or, if desired, make them publicly available. Available for classification tasks only.

For logistic regressions, note that it has been called confidence. However, it will be deprecated soon and only this property will be supported in the future. This is the date and time in which the prediction was updated with microsecond precision. For classification models, confidence is the lower end of a binomial-style confidence interval, where 1 indicates absolute certainty and 0 indicates no better than a random guess.

Technically it is the lower bound of Wilson score confidence interval for a Bernoulli parameter. Read how it works in layman's terms here. For regression models, confidence is the upper end of a confidence interval around the expected error for that prediction. The prediction goes through a number of states until its fully completed. Through the status field in the prediction you can determine when the prediction has been fully processed and ready to be used.

Most of the times predictions are fully processed and the output returned in the first call. These are the properties that a prediction's status has:To update a prediction, you need to PUT an object containing the fields that you want to update to the prediction' s base URL.

Once you delete a prediction, it is permanently deleted.
