18 forum posts | I make glue…
wooden splints, cheap as chips and not as bad as plastic, just throw them away.
as someone else said, glue is sticky. when dry / cured you may be able to peel it from the Teflon but no just don’t do it. |

When using complex chemical mixes for critical applications - any 2 pack glue/paint/filler/rubber/etc - using one use disposable mixing cups, stirring sticks, gloves, applicators is better than buggering up the cure and effect by reusing old ones. Shop rags are the same, you don't know what it was soaked in before you tried wiping down your expensive new paint job. Edited By Nicholas Wheeler 1 on 24/01/2022 23:32:02 |

But it's not cheap stuff. What thickness do you think would suffice? 2mm? 3mm? I have no idea how flexible and/or physically strong the stuff is. Although the Ergo Square doesn't have a handle it it might have had merit in boing thinner & much more flexible... but either way, being PTFE I guess they would be dead-easy to wipe clean. Might work (??) J Edited By John Smith 47 on 25/01/2022 01:11:30 |

157 forum posts 26 photos | Hi, It is possible to powder coat teflon onto a metal base. If you got a stainless steel spatula with the dimensions and flexibility you required a powder coating firm should be able to put a teflon coat on it for you. I use a piece of scrap teflon sheet to mix epoxy glue on. The wet glue sticks to it but easily peels off when it has cured. If you want the glue to not adhere to the spatula when you are smoothing it out, your best bet is to coat the spatula with a liquid which the glue won't stick to. For example, the packet my silicone sealant came in recommended dipping the tools your using in water with a bit of detergent in it. Just be careful the liquid you use doesn't interfere with the adhesion properties of the glue - silicone oil would be a definite NO I would guess. Regards, Alan C. |

2661 forum posts 294 photos | Perhaps the answer is to go back to biodegradable glues - hide or pine resins or bluebell mucilage or egg proteins spread with wood or cardboard spatulas and then composted. pgk Edited By pgk pgk on 25/01/2022 06:37:01 |

![]() 25215 forum posts 3105 photos 1 articles | Why not use some scraps of ABS or rubber, it seems none of your glues will stick to that, allow to set and peel it off any residual glue so you can use again. Just cut a strip from a Poly Prop bottle or container and put it back in the recycling after use. Notched or comb spreaders give a more measured and constant film thickness. If you use a flat spreader it is hard to tell if you have the same amount of adhesive over the whole surface. A notched one will leave a constant height bead and remove the rest of the adhesive between notches so when you put the parts together those beads spread to an even thickness. I used notched spreaders a lot for work. These days Vegans may not approve of some of the old adhesives PGK suggests

Hello Is it possible to buy a spatula made for Teflon (or something similar that is totally non-stick) for spreading glue? Thanks Actually, you might want to consider what the English Ashes team use to coat their gloves with as nothing sticks to that. I heard that Novac J is being considered as a batting coach for the English cricket team as it took almost two weeks to get him out. For spreading epoxy, nothing beats an old credit card.

![]() 3445 forum posts 62 photos | The main requirements are that the spatula should be flexible and very smooth. The peel strength of most glue is fairly low so with a flexible spatula the spatula can be peeled off the glue. regards Martin |
