Troubleshooting for soft, wet or sticky surface


Reason -1- under-mixed - Mixing is a crucial part of the project. Mixing of the product should be done by hand with a clean stir stick. The more product you are mixing, the longer it will take to achieve a complete mixture. One gallon of the mixture takes approx. 4-5 minutes of mixing. Two gallons of mixture take approx. 6-7 minutes of mixing. Timing this with a watch is a good idea. While mixing make sure to scrape the sides and the bottom of the container to avoid under cured epoxy. Be sure to push thoroughly down with the stir stick or, you can end up with areas that are hard/dry with other areas that are sticky or tacky that will not harden.

Reason -2- inaccurately measured -  If you have measured and mixed your resin correctly, this problem will not occur. You must follow the strict 1 to 1 ratio by volume. Do not guess or eyeball these measurements. Just dumping the product from their original containers is not a proper measurement.  It must be measured with reasonably precise accuracy using a graduated tub.

Solution -  Entire Surface - Soft, Wet or Sticky  -

1) If your surface is hard but only slightly tacky -  a new flood coat can be applied over the entire surface, and it will dry hard and crystal clear assuming the mixing procedures have been appropriately followed. No sanding is necessary

2) If your surface is wet and soft or gooey like jello - removed as much of the material as possible with a paint scraper or knife. Use denatured alcohol or acetone when necessary to help remove the wet epoxy. Remix and apply a new flood coat. The new coat will cover up almost all effects of the previous error. Be sure to follow the proper mixing procedures.

Solution:  -  Some Areas - Wet, Sticky or Soft Spots  - 

1) If spots have a slight tackiness on the surface - you can mix up a very small batch of epoxy and paint over those areas with an artist paint brush. Make sure to dip the brush into the center of the container to ensure that you paint on blended epoxy instead of touching it to the sides of the container as you might end up with the non-mixed material. You may also repour over the entire surface, and the new product will dry hard assuming correct pour procedures have been followed.

2) If these spots are soft and wet on the surface - you will need to scrape or cut out as much of the soft material as possible using a paint scraper or knife. Use denatured alcohol or acetone when necessary to help remove the wet epoxy. If you are left with deep depressions. As a result, your first re-coat should be used just to fill in the areas in which you scraped. After this pour has set for at least 4 hours, a full re-coat can be completed. This will hide the imperfections and leave you with a hard glass-like surface.
