Celia UK Posted August 2, 2015 Report Share Posted August 2, 2015 The kiln wash on my shelves has been flaking off recently, sometimes one layer, in some places 2 layers right back to the shelf. I'd like to remove it all and start over. What's the best way to fo this? Is a sanding/grinding disc the only option? I don't want to end up with gouges in the shelf surface.

Marcia Selsor Posted August 2, 2015 Report Share Posted August 2, 2015 If your aren't grinding glazes off, you could get a wire brush for a drill.Lightly as you go. Wear goggles,hat or scarf, work shirt and respirator. do it outside if possible. Marcia Link to comment Share on other sites More sharing options...
Denice Posted August 2, 2015 Report Share Posted August 2, 2015 I would guess it depends on your the kiln wash you used, I usually scrape it off with a putty knife. The wire brush sounds good for some really stuck areas. Denice Link to comment Share on other sites More sharing options...
Patat Posted August 2, 2015 Report Share Posted August 2, 2015 I use an old piece of kiln shelf (a hard brick or soap works too). Slide it back and forth over your shelf like a scrub brush. It takes a little longer, but makes a nice smooth flat surface. Personally, I never go right down to the shelf, I just scrub until loose bits are gone and surface is flat. Then put on a new layer of wash and lightly scrub that back. But I like thick kiln wash cuz I like runny glazes.... Link to comment Share on other sites More sharing options...
Celia UK Posted August 2, 2015 Author Report Share Posted August 2, 2015 A few things to try here - might get my husband on to this - I've just done 3 hours gardening, so he owes me! Link to comment Share on other sites More sharing options...
GiselleNo5 Posted August 2, 2015 Report Share Posted August 2, 2015 I learned to do it with a handled pumice stone. Works pretty well. Also, my friend was using a commercial kiln wash mix and it was coming off in huge flakes down to the shelf and she got a recipe that solved the whole problem. Before, the shelves had to be done pretty much with every firing. Of course, this never happened so her stuff kept getting ruined. Link to comment Share on other sites More sharing options...
GiselleNo5 Posted August 2, 2015 Report Share Posted August 2, 2015 Let me know if you'd like the recipe. Link to comment Share on other sites More sharing options...
Judy_in_GA Posted August 2, 2015 Report Share Posted August 2, 2015 Do you know what commercial mix she was using? I bought some but I haven't redone all my shelves yet. I'd just as soon toss it if I'm going to have to redo the shelves every time. Please post the recipe. Link to comment Share on other sites More sharing options...
Tristan TDH Posted August 3, 2015 Report Share Posted August 3, 2015 Iwent to the hardware store and got a floor scraper. Its about 18: long very heavy duty has a removable blade that is about 1/4 inch thick at the back , non sharpened end. it's intended to remove adhesive and linoleum from a floor before you install new flooring... It works SO WELL it takes all of the kiln wash off easily in one pass usually. Works so much better and with less dust than when i used to sand then use a wire brush and a smaller less industrial scraper. Link to comment Share on other sites More sharing options...
Thuraya Posted August 3, 2015 Report Share Posted August 3, 2015 I use one of these, it takes the kiln wash and most small glaze drips off in about 30-60 seconds and i'll never go back to scrapers. Link to comment Share on other sites More sharing options...
