Hello @suley001 

Welcome to Bunnings Workshop. There are always factors to consider for long curing times such as temperature, humidity and sunlight. Too much or lack of these elements causes unpredictable drying times. You could artificially hurry up the process by using a fan or heat gun but it would only dry the surface and it would still be soft at the bottom. To prevent accidental water from entering your pond I suggest covering it with a tarp, make sure it does not touch the pond sealer. In these instances if it still feels too soft to the touch you may have to wait a few more days with good sunlight until the sealer cures to full strength. At the back of the can are instructions for moisture cure test. You can give that a go to test if it's cured. If there is anything else we can help you with please post it here on workshop. 

Cheers,

Hi @suley001,

How's the area looking now, and has it cured at all? After speaking with Crommelin, they've suggested that the area will probably just take longer to dry. As long as the area isn't flaking or bubbling, it will be fine. If it doesn't cure or starts bubbling, you can cut the affected area out with a Stanley knife and peel it away. Ensure you dry the area thoroughly and apply two fresh coats of sealer over the cutout section.

Please let us know how you go or if you have more questions.

Hello, I used the clear pond sealer about two months ago and followed all the instructions correctly but my project is still not dry when put in water.

How can I get it to dry?

Hello @THowell

Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about the Crommelin pond sealer.

Four weeks is a long time to wait for the sealer to cure. As I've mentioned before in this discussion, the only reason there would be a delay in the cure time is because of the temperature, humidity and sunlight. Any of these factors would be enough to delay or retard the drying time of the product.

Would you be able to post a picture of the location of the pond? This will allow our members to assess its location. We can then make recommendations on what steps to take. Has there been a lot of rain in your area lately? Has it been very cold for the past few weeks? Is full direct sunlight reaching the pond that you sealed? 

My only recommendation to accelerate the drying time of the pond sealer is to use a heat gun. However, too much use of the heat gun will damage the surface of the sealer. 

Please keep us updated with your progress, we look forward to seeing your pond sealed and ready for use.

I used it to seal an ornament so it was safe to place in a fishtank.

I have kept it inside the whole time.

I even waited two weeks before putting it in water.

It wasn't dry so I tested it once a week only to have the same outcome.

Hi @THowell,

That sounds quite unusual for the pond sealer not to have cured. I'll contact Crommelins first thing in the morning to see if they can assist.
