What is your best product for gap-filling?
Depending on your specific application, there are any number of options. If you want a clear product, or one that can be colored, a pourable, self-leveling epoxy like Mirrorcoat® or Mirrorcast™ will work very well. For vertical surfaces, a non-sagging product like Gel Magic, primarily used as an adhesive, is easily mixed and spread, filling gaps without shrinking.
How many years of protection is the Board Defense borate powder rated for?
The Board Defense powder is really designed to be used as a first step to our System Three End Rot System to make sure that wood destroying organisms are killed before it is repaired and patched. It is effective in destroying any decay, insect, or fungi in the instant it is applied and can last for a few months without any other protection. For long lasting repair and protection, please check our End Rot system here: https://www.systemthree.com/pages/rot-repair
How do I thin down or lower the viscosity of the Marine Spar Varnish?
The Marine Spar Varnish can be thinned with mineral spirits at up to 10-15% by weight.
Marine Spar Varnish Over Sanding Sealers
System Three® Marine Spar Varnish can be used over some sanding sealers but it will depend on the formulation of the sealer. Most lacquer-based sanding sealers are not recommended because the sanding aids are wax-related. We recommend testing the varnish over any other sealers in a small section to ensure you get good adhesion between the two coatings. Also, for future reference, the Spar Varnish does not require sanding in between coats if applied within 12-24 hours of the initial coat.
How can I repair wood rot?
System Three® offers the End Rot® Kit, a group of products which kill rot, repair the wood, and keep the rot fungus from coming back.
What is the proper surface preparation for gluing wood to metal using G2?
Make sure that the surfaces are clean, sanded, and free from contaminates. Best results are achieved by adding some silica thickener to the G2. Also, apply only enough clamp pressure to close the joint. Over clamping will squeeze out the G2, resulting in a weak bond.
Can I coat urethane (poly iso) foam with epoxy?

How much working time do I have with my epoxy?
See Technical Data Sheet or container for working times.
The Part B hardener has gotten darker over time. Can I still use it?
Probably. Hardeners yellow and darken over time due to contact with air and sunlight. This does not affect their performance. If the batch date is older than 3 years, to satisfy yourself do a small test and make sure it cures properly. Batch code: X(YEAR) XX(MONTH) XX(DAY) X (INTERNAL CODE).
How long should I wait in between coats?
See Technical Data Sheet or container.
My epoxy resin is taking too long to cure. How can I speed it up?
The only way to speed the cure of our epoxy resin products, once they've been applied, is to heat the room or the area that your project is in. Every 18°F (10°C) increase in temperature cuts the time it takes for the resin to cure in half.
