Midwest Hearth Clear Aquarium Silicone Sealant - 10.2 Fluid oz Cartridge

very good

Seems great it skins up nicely allowing time to work

la verdad al inicio se me hizo caro pero ya probandolo me encantó y me sentir que valió cada peso. Me ayudó a pegar el fondo 3D y pequeños espacios que tenía en la pecera.

Purchased this for a fountain I made. Works fantastic. Dries clear. Seal & strength is perfec. Thank you!

Fast delivery. As per specified.

This is an outstanding product if you are resealing an aquarium or building new. It is much more costly than the silicones you can find at your local hardware store but FOR THE PURPOSE worth the money. There are two downsides that you learn from experience. (1) You need to allow a full four days for it to cure before adding water. If possible don't move the aquarium at all during that time. Impatience is likely to have you cleaning up puddles and require you to start the whole process over (including trimming ALL the earlier silicone away). (2) Because of the slow curing time, trimming any blobs where you don't want them needs to also wait on the curing, otherwise it will smear and prove to be a bigger task than it would have been with patience. Thorough preparation is needed. Trim ALL old silicone away with an exceptionally sharp razor blade and wash repeatedly with vinegar. (I never go so far as to try to separate the glass pieces.) The new silicone WON'T adhere to the old. Wipe dry with a clean lint-free towel and allow an additional 12 hours or more to air dry. Apply a good thick bead of silicone and press into the corners by running your finger along all joints while the silicone is still very soft. DON'T try for as narrow a bead of silicone as possible, especially when resealing an older aquarium. There is A BIT OF FORGIVENESS for spots of old silicone remaining if your new seam goes beyond them. Then BE PATIENT.
