Holly Himes Posted October 14, 2020 Report Share Posted October 14, 2020 I made a kiln wash of 50% EPK and 50% alumina hydrate and some of the wash is seriously flaking off the shelves. We sanded the surface of the old shelves, wiped them clean and then applied the wash with a brush. Is it too thick, shelves damp? Need some guidance Link to comment Share on other sites More sharing options...
liambesaw Posted October 14, 2020 Report Share Posted October 14, 2020 You want half the EPK to be calcined so it doesn't shrink as it dries. Also thin layers. Link to comment Share on other sites More sharing options...
Bill Kielb Posted October 14, 2020 Report Share Posted October 14, 2020 Lee’s kiln wash is the only wash I know of that stays on like iron and does not flake off. The recipe is secret and way better than the 30 recipes I have tried. Much more costly than making your own though. Link to comment Share on other sites More sharing options...
Mark C. Posted October 15, 2020 Report Share Posted October 15, 2020 Wash is to thick and you need 1/2 the epk to be calcined. Then apply two thin coats drying 100% between coats . I like a paint roller and have it mixed to heavy cream consistency. I use a paint roller drop in screen in a 5 gallon bucket. you can still use what you have just add more of the right materials to make it whole Link to comment Share on other sites More sharing options...

Piedmont Pottery Posted October 15, 2020 Report Share Posted October 15, 2020 You can also add about 1% minspar 200 to the EPK/calcined EPK/alumina hydrate mix to have it adhere better without flaking. Link to comment Share on other sites More sharing options...
