LisaMW Posted December 4, 2019 Share Posted December 4, 2019 Has anyone ever used the rubber plugs to seal the mold hole. I usually cover the hole with a wick sticker and then cover the sticker with mold sealing clay. I don't generally have any problems. If there is a leak, it is typically a small leak that seals itself. Today I ran out of clay and tried mechanical duct tape. I ended up with a giant mess. Before I order more clay, I'm wondering if anyone has ever tried the rubber plugs? Do you trim the point down? How many times can you reuse them? Do you cover the plug with tape or clay for extra leak protection? When I order more mold sealing clay, that will be the only thing on my order. It's a small item compared to the shipping, so I was looking for thoughts on the plugs before I pace the order. Quote Link to comment Share on other sites More sharing options...
TallTayl Posted December 4, 2019 Share Posted December 4, 2019 I use high temp metal tape, the stuff used for car exhaust systems or high temp HVAC pipes. Quote Link to comment Share on other sites More sharing options...
bfroberts Posted December 4, 2019 Share Posted December 4, 2019 I wouldn't bother with the plugs. I had horrible luck with them. I use the same metal tape as TT. Hubby was an HVAC guy, so we have tons of that anyway. Works like a champ. Quote Link to comment Share on other sites More sharing options...
LisaMW Posted December 7, 2019 Author Share Posted December 7, 2019 Thanks, I thought the tape I tried would be strong enough to handle the heat, but I guess next time I'll have to get some HVAC tape. Quote Link to comment Share on other sites More sharing options...
