Canoe Mold Build Day 8

Filling spaces with mud

Filling spaces with mud

Day 8 we focused on finishing up shaping and sanding the mold. As I have mentioned before this step of the process is about care and patience. Take your time to get the mold just right as the canoe is going to come off as a complete duplicate of the mold. There is not going to be much flexing or twisting that will allow you to “correct” any oddities in the shape.

Mudding

Due to the fact that Moran gives us the guidance of having up to a half inch of gap between the foam, we realized that mud was going to need a decent amount of time to dry at that kind of thickness. So in an effort to speed up the drying time and reducing cracking I started the mudding with a simple crack filling layer. All I did was filled the large cracks that I knew would take at least few days to dry. And I was correct, the larger cracks took almost 3 days to finish drying.

Another technique I used to avoid cracking in the mud was to add water to the premixed mud. Out of the packaging the mud is about the conistensty of cake icing. To get a smoother application and less cracking I added water to achieve a consistency of pudding. While this does increase dry time the decrease in cracking is well worth it since you will spend less time applying additional coats plus you will not need as many coats. There was no precise measurement of water I added, it was essential based on visual consistency.
