Slate Filler?

What material would be best to use to fill chips and cracks? One area is pretty sizeable, it's like the slate was delaminating. Is Bondo best used in this kind of repair, or maybe like a two part resin filler?

Thanks for any info that can be given.
 
Do you mean cracks that go all the way through the slate? Or chunks missing from around the slate seams where the pins within the slate popped it.

Sometimes wax can be used and is the best. Waterputty is ok but if you have a large enough area waterputty will crack. Bondo works best for large chunks missing.
 
I can't remember the name of the product......but, it has a fellow on the can that looks like the old Ajax bald guy flexing his muscles :rolleyes:

It's some type of plaster type material -- you just add water -- turns yellow and is extremely hard.

Don't leave to much on the slate cause it's hard to sand after it dries but, lasts forever;)

Sounds like the one you're thinking of is Durham's Rock Hard (Watter Putty). I was planning to use that one myself. I've only done one table so far, and learned the hard way about what you said -- its a royal pain to sand. They have a tip on their website that I'm going to try this time (let set for 20 minutes and then shave excess off, leaving very little to sand):

I also have some chunks missing from the slate seams as Smittie described. There is one chunk missing along the seam edge that is about two inches wide (along the seam), half an inch tall, and half an inch long in the lengthwise direction of the table. Another missing chunk is circular, slightly larger than a quarter, and maybe about a quarter inch deep.

Unfortunately, the area that I live in gets too warm for beeswax in the garage (my last table got a wax mark through the cloth along the seams in the Summer), so I'm stuck with either the Durham's or Bondo. I'm not sure if the slate craters would be considered too big for Water Putty to work well, or if I should go with Bondo. Since I'm a newbie at this, I'm a little nervous about using Bondo, in case I screw up.

Is Bondo any harder to work with than water putty? I know I should score the Bondo at the seams or else it will probably chip the slate due to the extremely strong bond. Is it a big pain to get all the Bondo off the seams for a fresh start on the next assembly?

I know what you are talking about. One day we had a T-rail we needed to set up that had a 8" long chunk missing that went to the edge of the table.

We went to home depot and looked for the muscle man but they did not have it. We like the muscle man because it dries faster. With the waterputty we were there a while trying to get it right.
 
Slate Filler

I use Bondo to fill seams and fix slates. To glue slates that have cracked, they have some good epoxies and gules to use. I will use water putty when I am doing a job and I do not really know the people and do not want to smell up thier house.
