Glass cast 3 drying time on a penny floor

We have laid a penny floor and 42 hours ago we sealed it with the glasscast 3 resin. However we are  little bit concerned that 42 hours later, although most of it is rock solid there are still a number of sticky patches remaining is this normal??

Hi,

There's no set solvents to avoid as such but  as mentioned above don't leave things immersed for a long time.  You can use acetone to wipe down the coins, although only use what you need rather than soaking the coins for a period of time. Most solvents or acidic/caustic cleaning agents will strip off the oxidization off the coins leaving them as new. - coke is a classic example of this - a few pennies left in a glass of coke overnight will be shiny and clean by the morning in most cases. wiping it for short periods to clean resin residue is unlikely to do this unless you are using something very strong like industrial acids or similar.
