Black Pudding filling compound mix

I have read the term black pudding, a tar and portland cement mix used to make a strong filling compound for larger working boats, the caulking we have just removed is definitely tar based and had badly blown and cracked, after replacing the decks with Isoflex a liquid rubber mainly used for flat roofs which replaces tar we are going to do a test with Isoflex and portland cement make a paste and test its drying time and strength.

Isoflex data sheet.

We will post our findings.

The result after one night, a success

For any caulking enquiries please call A and D Wooden Boat Marine Services 07765 195 118.
