901 White Seam-Fil 1 Oz Tube

This worked perfectly on a laminated counter top that had knife cuts due to slicing fruit. They are not visible now - great product

The SeamFil product was easy to use and worked as advertised. For deep chips in Formica countertops, more than one application may be required as SeamFil does shrink a bit as it dries. For cracks and seams between separate pieces of Formica, SeamFil bridged the gaps nicely. Recommendation: watch the YouTube videos before using SeamFil as there are valuable tips on applying the product. My fault entirely: I bought the white SeamFil because it seemed closest to the color of my kitchen Formica countertop which is sort of a faint parchment/bluish color. The white SeamFil stands out glaringly. Perhaps I'll try spilling coffee on the repairs and see if the white can be toned down.

This smoothly covered the cuts in my white formica kitchen counter, but when it dries it is a light yellow, so the spots I filled stand out. I thought it was supposed to dry white. Now I need to research it and find some sort of white paint to cover those new spots.

This worked great for repairing my countertop, can’t even see the cuts after applying.

So easy to use. I had slashes--like from knives-- on my Formica. I put a small amount on a paper plate, stirred it with a toothpick until it got thick--just a few seconds. Then, I painted it with the toothpick--using a stroking motion. It dried within 10 minutes. I put a bit too much but used a clean sandpaper block n gently brushed it until smooth. Within a few hours, it was perfect! You couldn't even see where the original mark was. I used the same technique for other marks. I was very happy n very impressed!

I'm a furniture-maker who usually works in solid wood and ply, but for this project, white melamine was the best choice. I bought the seam-fil to fill and disguise the inevitable chips in the melamine from cutting on the table saw. The seam-fil recommends working it until it is thickening, but that didn't work well for me, so I started using it right out of the tube like the other reviewer. Using either method, the seam-fil doesn't really fill the chips. It turns them white and kind of plasticky looking so the chips are somewhat camouflaged, but there are still depressions in the surface. Also, you need to tape off the good melamine or it will change the sheen of those surfaces. It recommends a specific solvent, which of course I don't have, but I found acetone works pretty well for cleaning off residue (after scraping with a knife)...but do yourself a favor and tape off a clean line. I thought this might be a revelation that would allow me to invisibly seam 2 pieces of melamine together, but unfortunately, it is not. If I had time, I would probably just fill the chips with my regular wood putty and paint the whole thing with plastic paint.

I've used this product for years on melamine surfaces on drafting tables. Application was smooth and made for a seamless surface even under the pencil and have had repairs last a decade...and still going

Worked great, made my cabinets look seamless. : ) Perfect color match for 20 yr + white melamine foil cabinets. Used color 901 white.
