« Part 5: Further grouting experiments Part 6 of Fibonacci Mosaic box series no next part

Firstly it occurred to me that although I needed a pattern to experiment that it didn’t need to be fancy. To this end I took a scrap of MDF and cut 2 mm slots in it using the table saw blade set low.

Applying the caulk using the gun and fine nozzle was like trying to pass an elephant. Slow and painful. So I decided to use a putty knife to apply it.

This stuff cures by losing water so I expected some shrinkage and because of that didn’t level it off completely.

After a day this was the result.

Shrinkage evident. So sanded back level this is what I had.

It is not hard but flexible even when cured. I spray coated some acrylic finish . This appeared to take well.
Left the piece until today (5 days total) with this result

and the end, sanded off flat

Some further shrinkage. Though I don’t think its an unattractive result. The filler is still elastic. May be a better long term bet given wood movement. We shall see. Thats all.

Be seeing you.

Martyn -

Interesting as always. What about a classic wood filler – sawdust and glue, colored to suit?

Yes, Steven. Another possibility. It might be difficult to get a light colour though, such as white. Darker should be fine though.
