More than a Face Lift

Many of you may have read in a previous blog that there are three rules aboard Mary Rose.

1. Keep the water out.

2. Keep the people in.

3. Don't hit any hard stuff around the edges of the water.

Well the "Face Lift" deals mainly with rule #1, Keeping the water out! The caprail is the very top teak board the spans the deck and hull at the top of the bullwork. If water gets under the caprail in runs down the hull and into the boat. This is a cause for rot, mildew, and if enough water gets into the boat it could be a dangerous situation in heavy seas. The existing caulk was cracked, torn and missing in some of the places. This is a routine maintenance issue and this application should last for at least 7-10 years. When the caulk is removed the exterior paint is damaged so that accounts for the new paint on the sheers. The process goes something like this.

1. Cut and pull out all of the old caulk.

2. Sand the space where the caulk will go and also the edges of the caprail and sheer where the caulk will overlap and seal.

3. Tape the caprail and sheer to define a caulk line area.

4. Clean the gap and overlap area very well with acetone.

5. Apply caulk and force it well into the gaps. I used Teak Decking Systems, SIS 440 White.

6. Smooth the caulk with finger and force it into the gap.

7. Remove caulk from finger with mineral spirits.

8. Let caulk cure for about 45 minutes and remove tape. (repeat step 7)

After 24 hours the area can be taped at the caulk line for painting. The admiral asked me why I did not caulk after painting and applying the wood finish? The SIS440 caulk will stick to almost anything but it will adhere much better to clean well sanded surfaces such as bare wood and gel coat. So in order to get the best adhesion, I decided to take the extra steps and apply the wood finish and paint after the caulking process. So you can see this is a labor intensive project with a real benefit as we prepare for our long distance voyage. I estimate that both sides will take about 2-3 weeks. It seems a bit long but you have to wait 24 hours between coats of wood finish and 16 hours between coats of paint. This adds up to a week, if you do the math for three coats of wood finish and three coats of paint. The photos show the old caulk, the prepped area and the caulking. We will post final pics after the starboard side is complete.
