Primer and Topcoat

Application Guide

1) Climate Control:  Try not to apply on days where relative humidity is above 70%, or the temperature below 50°F. Do not apply on rainy days, even if the boat is covered (unless you can add post heat and/or dehumidify the area).  The best environment to apply Wetlander is one that is warm and dry with good air flow.  In warm weather, apply outside in full sunshine.  In cooler, humid weather, apply inside and utilize space heaters, dehumidifiers and fans for the very best results.

2) Surface Prep:  Clean and “roughen up” the surface of the hull by sanding with 100-150 grit paper. This enhances the adhesion of Wetlander to the substrate.
Then, wipe down the entire area to be coated with an acetone dampened rag. This removes sanding dust, oils, waxes and any other contaminants that could adversely affect adhesion. Keep wiping with the rag until it comes away clean.
Lastly, tape or mask off the area to be coated.

3) Choose an Application Method:

.5 inch mini rollerIf rolling,…  Use a 1/2 inch or 3/4 inch roller on a “mini-roller”.  Rolling is the easiest method if your boat is not flipped over and/or still on the trailer.  It is also the fastest in terms of prep and clean-up.  If you don’t have spray equipment, or have never used spray equipment, you should apply with a roller.  Pro-Tip: Keep a foam brush handy for hard to reach areas and welds, rivets, and seams.


husky siphon fed cup sprayerIf spraying,…  Use an airless or air assist sprayer.  This is the preferred method for builders, fabricators and applicators because more coating can be applied at once and provides the smoothest surface.  You should be able apply 10 to 12 wet mils without fear of sagging. Avoid the cheap yellow plastic electric sprayers from the home center.  Pro-Tip:  Always keep a roller handy, just in case your spray equipment fails.

4) Mixing Instructions: Wetlander is a 2-component product. The entire contents of each container should be mixed together.  Begin by shaking both the "A" and "B" components violently, at least 30 seconds each.  Then, pour the B directly into the A container. Mix the A and B until completely blended.  Once catalyzed, Wetlander has a workable pot life of 1 hour.

5) Primer Application:  Begin applying Primer either by roller or spray.   Apply all catalyzed Primer within one hour. When rolling the first coat, Wetlander will fisheye or separate –this is normal.  Simply wait a few minutes and then smooth the coating out with your roller. The fisheye will diminish.  Sprayed Wetlander can sometimes have a slight “orange peel” appearance.  Let the Primer cure for at least 24 hours.  For the very best results, wait 2-3 days before applying Topcoat.  *If you are applying a Wetlander 3 Layer Kit, simply repeat step 5 for both 1L and 2L Primers, then move on to step 6 for 3L Topcoat.

6) Topcoat Application:  Begin by lightly roughening the cured Primer layer with 220 grit sandpaper. After roughening, wipe the Primer surface with a damp rag to remove sanding dust.  Apply Topcoat.

7) Curing:  Wait at least 5 days before putting the boat back into service. If you can press your fingernail into the coating IT IS NOT FULLY CURED YET. Adding heat after application, either by heaters, direct sunlight or other method, will increase the rate of the curing process and will provide a harder coating.  Do not exceed 250 degrees Fahrenheit if using post heat.  Cool and humid conditions will slow the cure, so be patient in those conditions.

Clean Up:  You can clean uncured Wetlander off of your equipment by thoroughly rinsing with water.

Touchups: Lightly scuff the area to touch up, wipe clean with acetone, allow the acetone to evaporate, then apply Topcoat. Allow 3-5 days to cure.


Extra Tips

Masking tape and registration stickers do not adhere well to a Wetlander coated surface. Plan your masking and state ID stickers accordingly.

If you only want to use ½ of a container, simply pour out ½ of the A and ½ of the B into a clean container, and then mix well.

On aluminum boats, try to apply the Wetlander within 12 hours of prepping with sanding. Aluminum does oxidize.

Warning:  Store Wetlander containers at room temperature.  Do not allow to freeze.  Wetlander has a shelf life of 6 months.  To prolong shelf life, shake the bottles often. Contents WILL settle to bottom.
