Answer This Question

A: Thank you for posting your inquiry on DAP All-Purpose 100% Silicone Adhesive Sealant. DAP All-Purpose 100% Silicone Adhesive Sealant's use is limited to tanks sizes of 30 gallons or less and 18” or less water height. Given the volume and water height of most "stock tanks", it is likely to exceed this limitation. Likewise, this formula is not recommended for use on galvanized steel. Should you have additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.

Q:Would I be able to use this to fill in small holes drilled into a 5 gallon bucket?

by|Jan 1, 2021

3 Answers

Answer This Question

A: Thank you for posting your inquiry. 5 gallon buckets are most commonly made with HDPE (High Density Polyethylene). Due to HDPE’s low surface energy (slick/nonporous properties), this type of plastic is extremely difficult for most products to develop proper adhesion to. Of note: Even when an initial bond appears to be formed, they are not typically considered high strength or permanent (especially when flexing, wide temperature fluctuations and/or moisture exposure occurs). Should you have any further questions or wish to discuss this, please feel free to contact DAP’s Technical Customer Service Department at 888-327-8477.

by|Jan 4, 2021

A: This product is wonderful but in this case, you would be better off spending your money on another 5 gallon bucket.

by|Jan 2, 2021

A: yes you can.

Great for coating small custom fish tank ornaments!

Stuff is great...nothing else to say.. Tip for the cap breakers....put some vasaline in the tube end or in the cap before you put cap back on and don't muscle it.

I used it on my toilet tank. It did not work. The toilet tank still leaking. I tried with different product that I bought at ACE hardware store and VOILA!!!!!!! It works.

Thank you for posting your feedback. We are sorry to see your low star review on DAP All-Purpose 100% Silicone Adhesive Sealant. This product is only intended for use in submerged applications when applied to glass. Likewise, the product must be applied to clean/dry surfaces and permitted to fully cure before it can be submerged. For submerged repairs on other materials, the use of a two-component epoxy would typically be recommended. Even these more specialized products do not typically result in a permanent repair when used as you describe. DAP

Works good, but dries out in the tube.

I use the DAP All-Purpose Adhesive Sealant for many jobs. Its initial setup time (about 45 minutes) is pretty good, and fully cures within 24 hours. It really needs a better cap. The cap has broken on 6 tubes of partially used adhesive, allowing them to dry out and become unusable.

Thank you for posting your feedback. At your convenience, please reach out to DAP's Technical Customer Service Department at 888-327-8477 so we can arrange to provide you with replacement caps.

Decent silicone, ridiculous packaging. Tiny tubes requiring multiple packages to complete a project , and impossible to squeeze out a consistent bead or get the last 1/4 of the product out of the tube. This would work much better in 10oz 'caulk gun' style tubes.

Thank you for posting your review. DAP All-Purpose Adhesive Sealant (Aquarium Silicone) is only packaged/available in a 2.8 fl. oz. squeeze tube. This product is marketed for use in small household repair applications and when used as an aquarium sealant, its use is limited to tanks of 30 gallons or less, where the water height is less than 18".
