Most failures in epoxy fillers result in the improper mixing of the two components, which results in a non watertight repair. The following instructions detail how to ensure you obtain a fully watertight filler by thoroughly mixing the two components of Fill-It. This is essential if you wish to use your epoxy filler for use below the waterline.
Measure Fill-It Epoxy Filler
Measure out equal volumes of Part A and Part B, sufficient to the task at hand. 1ml fills a volume of 1cc, or one cubic centimetre. 1cu inch is 15 cubic centimetres, ml or cc’s. There is no shrinkage. use two separate tools to remove part A and Part B from their containers, unless the entire volume of the container is to be used at once!
For estimation purposes our packages contain the following amounts:
| Package | MilliLitres (cc) | Cubic Inches |
| 12 US Fl Oz | 355 | 22 |
| 2 US Pint | 950 | 58 |
| 1 US gallon | 3785 | 231 |
I like to mix by weight, the ratios are 92 parts A to 100 parts B by weight.
Mix the Filler
Mix the two-components on a flat surface, using a paint scraper, stiff-bladed putty knife or other similar tool. Use a smear-scrape-fold motion, scraping clean both the mixing surface and the tools occasionally.
Add colourant, and Mix the Epoxy Filler Again
When thoroughly mixed, sprinkle a small amount of the Black Powder Pigment on the mixed material.
Mix again, observing that dark grey streaks rapidly develop in the filler.
Continue mixing until the entire mass is a very light grey in colour, and entirely uniform in colour with no streaks or imperfections.
MakeWoodGood will supply an amount of black pigment upon request if Fill-It is to be used below the waterline for this purpose.
Add more colourant, and Mix the Filler Again
Now sprinkle about twice as much black powder pigment on the mixed material and repeat the above procedure.
The filler, if uniform in colour, is now ready to use, and the thorough mixing will ensure that it remains watertight and you have fill-it epoxy filler for use below the waterline.
