RotFix

  • What finishes are compatible over RotFix?

    We know that System Three® finishes, WR-LPU and Marine Spar Varnish 
    are compatible with RotFix™.  Nitrocellulose lacquer, waterborne finishes, and 2-part polyurethanes will work as well.  As far as oil and 1-part polyurethanes, you will need to test for compatibility.

  • RotFix as a paint primer

    RotFix Sealer is a great product for consolidating or hardening soft or rotted wood.  It's also useful as a general purpose wood sealer.  If you have wood to paint, and it's a little soft, but not rotted away to require a full repair,  Rot Fix epoxy sealer will act as a primer for paint.

     

Sculpwood Putty & Paste

  • Can Sculpwood Putty or Paste be colored?

    Yes.  There are a few options:

    1)  Dry pigments can be added into the mixed products in any proportion. 

     2)  Liquid dyes or paint colorants can be added into the mixed at up to 2% by weight.

     3)  System Three® Epoxy Paste Pigments can mixed into the Part A at up to 10% by weight and then mixed 1:1 with the Part B.

  • Can you stain over Sculpwood Putty or Paste?

    Unfortunately, no.  The resin content of the products is high enough to effectively have them function somewhat as sealers, and the stain will not penetrate like it will into the bare wood.

    The suggested workaround is to mix dry pigments or house paint colorants into the paste or putty as you combine the Part A and B.  This can approximate the color of the stained wood around it.

  • How soon can SculpWood Putty be applied over the RotFix Epoxy?

    SculpWood Putty can be applied over the RotFix immediately after application.

Mirrorcoat™

  • Can fine scratches or defects be buffed or sanded out of your products?

    Yes.  System Three® offers a sanding and buffing kit for sale on the website.  Contents are shown below.  The video shows its use with Mirrorcoat®, but it also works well on WR-LPU and coating epoxies like Silvertip™.  Click on the image for detailed information and to purchase.

  • What are the causes for fish-eyes or craters in Mirror Coat?

    MVI_2492.MOV.00_00_35_10.Still002.jpg

    From our experience, cratering or fish eyeing almost certainly indicate that one of three things occurred during your application:

    1. Insufficient drying and/or incompatibility with a stain or oil: Pre-testing is always recommended when using products from another manufacturer.

    2. Sanding too smooth can cause the epoxy to draw away from the surface. For example, sanding higher than 220 grit will make it difficult for the Mirror Coat to overcome the surface tension of the substrate. 

    3. Lack of coverage: We specify pouring the MirrorCoat at 4 oz/sq ft to allow enough coverage on the substrate. Any less will result in a lack of adequate coverage.

  • Mirrorcoat Heat Resistance/Temperature Tolerance

    The rule of thumb with cured Mirrorcoat® and how much heat it will tolerate is this:  If an object is not too hot to hold in your hand, you can set it directly on a Mirrorcoat surface which is completely (more than a week) cured.  If it is hotter, you must place a coaster or hot pad underneath the object.

    If you happen to put an object that is too hot on a Mirrorcoat surface, and it leaves a ring, the ring can many times be removed by passing a hairdryer back and forth over the affected area.

  • How is Mirrorcoat applied?

  • Mirrorcoat epoxy has cured with some sticky spots. How do I fix it?

    The sticky spots are most typically uncured resin or hardener which hasn't been completely mixed in.  If it's excess resin it can be removed with a strong solvent like lacquer thinner.  If it's excess hardener it can be removed with soap and water.  The voids can be filled with small quantities of newly-mixed Mirrorcoat, carefully using a spatula or squeegee to smooth out any excess material.  Let this cure 24-hours and lightly sand the surface with medium-coarse sandpaper.  Finally, apply an additional flood coat at 4 fluid ounces per square foot.

WR-LPU

  • How do I thin down or lower the viscosity of the WR-LPU Topcoat?

    The WR-LPU Topcoat may be thinned with clean deionized or distilled water at up to 25%. 

  • Custom colors for WR-LPU

    WR-LPU waterborne polyurethane topcoat comes in 12 standard colors.  We will match any color sample you send us for an upcharge with a minimum order of 1 gallon.  Small 4 oz. samples of all 12 colors are available for a nominal charge from the website.  These can be intermixed in any proportions to obtain the color you want in order to have it matched.

  • I want to paint a design on my wood/epoxy paddleboard but I do not know what kind of paint to use or when to paint.

    You can paint your design under or over the epoxy coating.  If it's underneath, ordinary house paint will do.  If it's on top of the resin, we would recommend our WR-LPU.

     

     

     

Miscellaneous

  • 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.
