Kampel SeamFil, ColorFlex and ColorFlex II: How to Read Kampel Numbers

Kampel Enterprises, Inc. (Kampel) identifies its SeamFil laminate repair and its ColorFlex and ColorFlex II caulks by number: 941 is a SeamFil color, CF8001 is White in ColorFlex and CF9001 is White in ColorFlex II. This guide explains what each product is for, how to read the numbers, what the two SeamFil kits contain and what Kampel says about SF99 solvent.

• SeamFil Color Matching Guide (PDF, 18 pages) - the 2025/2026 edition; page 12 lists the standard SeamFil colors and marks the kit entries

SeamFil, ColorFlex or ColorFlex II: what each one is for

SeamFil laminate repair

Kampel's SeamFil page calls it the "ORIGINAL" laminate repair, a one-part system to "Repair nicks, fill seams and make gouges disappear". SeamFil Facts describes it as "a single part, solvent based repair system for high pressure laminated surfaces" that cures in approximately one hour, with 24 hours recommended for total cure, and says it dries to a matte finish.

According to the same sheet, one 1 oz tube will approximately fill an 8 foot seam of counter with a 1/8 inch bead. A seam wider than 1/16 inch (it should never be larger than 1/8 inch) will probably need a second application, and SeamFil can fill an area up to 1/4 inch in diameter.

The sheet also states: "SeamFil is NOT recommended for use on Solid Surface materials." For solid surfaces it names Kampel's ColorFlex, ColorFlex II and KamSil products. We list ColorFlex and ColorFlex II, but not KamSil.

ColorFlex caulk

Kampel describes ColorFlex as "Custom colored acrylic latex caulk with silicone" for corner and perimeter caulking of decorative surfaces. According to the ColorFlex page, after a component such as a counter, vanity or bath surround is installed and its laminate seams are filled with SeamFil, ColorFlex seals the inside corners and the perimeter and, where flexibility is needed, fills gaps where components meet walls, floors, cabinets, tile or insets.

ColorFlex II caulk

Kampel describes ColorFlex II as "Custom colored high-gloss acrylic caulk", also used for corner and perimeter caulking, but its page says that, unlike ColorFlex, it has adhesive qualities that bond components together. Kampel lists its typical applications as "sealing miter joints, setting backsplashes on counter decks and caulking vertical and horizontal corners".

SeamFil color numbers: 901 to 946

Page 12 of the color matching guide prints the "COMPLETE LIST OF ALL STANDARD COLORS AVAILABLE": 22 three-digit numbers, each with a name. The guide calls them SeamFil color numbers and gives no meaning for the individual digits, so read each number as a whole. We list all 22 as 1 oz tubes.

Two entries have a special job. SeamFil Facts says that "To obtain a Glossy Finish, 943 Clear Gloss should be added" and that "To increase the cure time of SeamFil, 944 SeamFil Retarder can be added to the mix." Some of our titles spell names differently (Grey, Butcher Block); the numbers are the same.

A separate post in this series explains how to pick SeamFil and ColorFlex colors with Kampel's color matching guides.

Standard and Woodgrain SeamFil kits

On the same page, an asterisk marks the entries "INCLUDED IN STANDARD SEAMFIL KIT" and a dagger symbol those "INCLUDED IN WOODGRAIN SEAMFIL KIT". Each kit has 12 marked entries, and in both kits one of the 12 is 944 Retarder:

• Standard SeamFil Kit: 901 White, 902 Gray, 904 Tan, 913 Brown, 914 Black, 936 Primary Yellow, 937 Primary Red, 940 Orange, 941 Almond, 944 Retarder, 945 Spectrum Green, 946 Spectrum Blue.
• Woodgrain SeamFil Kit: 901 White, 913 Brown, 914 Black, 918 Mahogany, 931 Maple, 933 Teak, 935 Birch, 936 Primary Yellow, 937 Primary Red, 940 Orange, 942 Butcherblock, 944 Retarder.

Our SSK page is the Standard SeamFil Kit and our SWK page the Woodgrain SeamFil Kit. Each of the two pages lists the same 12 entries as Kampel's marks, plus a 1/2 pint of SF99 solvent, a putty knife and instructions. We list the five numbers that are in neither kit (903, 919, 934, 939 and 943) only as single 1 oz tubes.

ColorFlex CF8000 series and ColorFlex II CF9000 series

The ColorFlex Index prints 219 standard colors, CF8001 White to CF8219 Black, under the heading "NEW COLORFLEX / COLORFLEX II STANDARD COLORS", and gives this rule: "To order ColorFlex II, simply change the 8000 series to a 9000 series. Example: CF8001 White is a ColorFlex number - CF9001 White would be ColorFlex II." It also notes: "Printed colors will vary from actual ColorFlex and ColorFlex II colors."

The table shows the 16 ColorFlex colors we list as 4 oz tubes, a selection of Kampel's 219 standard colors, with the names the index prints.

We list ColorFlex II in five colors, also as 4 oz tubes: CF9001 White, CF9004 Pale Blue, CF9008 Almond, CF9146 Blue Iris and CF9193 Pumice.

SF99 solvent

SeamFil Facts states: "SF99 Solvent is the ONLY recommended solvent for use with SeamFil." It adds: "SeamFil can be successfully removed by SF-99 Solvent before or after it dries, regardless of the amount of time passed." And it warns: "SF99 Solvent is 100% VOC and will attack non-laminate surfaces like, finished wood, PVC, etc."
