Troubleshooting

Troubleshooting

1. Entire Surface Is Soft, Wet or Sticky after 48 hours:

 1. Product was under-mixed. Unfortunately, as much as we stress this as the most important part of the project, it can still occur and is the most common cause of this problem. If you do not mix long enough or do not scrape the sides and bottom of the container while mixing you will find under-cured epoxy. Please re-read Section 3 of our instructions.

 2. Product was inaccurately measured. 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. The product MUST be mea- sured with fairly precise accuracy using a graduated tub.

Solutions

 1. If the surface is hard but only slightly tacky, a new flood coat can be applied over the entire surface and the new product will dry hard assuming mixing procedures have been properly followed. 

 2. If the surface is wet and soft, then as much of the material as possible must be removed 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 certain to follow the proper mixing procedures.

2. Sticky or Soft Spots

The most common cause of this is scraping or brushing from the side or bottom of the mixing container while pouring. It is natural to want to use up every last drop you have mixed. However when you pour onto the surface you should just dump it out and set the container down. If you use a stick or a brush to try and remove every drop you will very likely end up with sticky spots.

 Solution

 1. If the sticky spots are hard but only have a slight tackiness on the surface then you can re-pour over the entire surface and the new product with dry hard assuming correct pour procedures have been followed.

 2. If these spots are soft and wet 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.

3. Air BubblesThere are many types and causes for excessive air bubbles. We have listed a few below.

1. Air bubbles across the entire surface.

a. No bubble removal technique was used as shown in Section 4 of our instructions.

b. Improperly applied or no seal coat was used.

c. Wood surface below was extremely porous and seal coat was not thick enough to cover. (Very common in aged wood).

d. Product was whipped or stirred excessively putting so many bubbles in the mix that they could not be removed with the flame/heat technique. Very common for users employing a drill mixer in their mixing technique or stirred the product too aggressively.

e. Dragging too hard with a brush on the epoxy while spreading. These tiny bubbles sometimes appear in cloudy streaks where the brushing technique was used. Consider using a rubber squeegee instead for spreading.

2. Air bubbles in just one spot.

a. Knot, cracks or holes in wood were not properly sealed and air bubbles continually rise throughout curing.

b. Missed a spot during the seal coat.

Solution: 

Usually the bubbles are not noticeable enough to warrant any further work. If, however, you desire, you may sand or grind the surface to remove as much of the air bubbles as possible and re-coat the entire surface.

 4. Surface Cures Uneven with Ripples or Waves:

 a. Wooden surface had too much warping or imperfections and one coat of epoxy was not enough to cover these issues.

b. Applying too thin a flood coat. This product needs to be applied in full 1/8” flood coats in order to properly self level.

c. Applying too much heat during your bubble removal techniques will cause a ripple effect. The heat gun or torch should be swept across the surface rapidly without holding it in one place.

Solution

Applying another flood coat in sufficient thickness should hide virtually all signs of the waves or ripples from the previous coat.
