12-Point Blister Restoration Program

12-Point Blister Restoration Program assures your vessel is restored to original condition. After inspection has determined that your watercraft has a large blistering problem, our restoration experts will restore your hull using our proven method.

Step 1. Remove The Original Gelcoat
The gelcoat is entirely removed from the vessel's hull below the waterline using laminate shaving equipment. We do this to expose all of the hull structural laminates/fibers, un-dissolved solvents, and to open up existing blister pockets/voids caused by the osmosis problem.

Step 2. Steam Cleaning The Hull
We aggressively Steam-Clean the entire hull, below the waterline. This dissolves and removes all un-dissolved solvents/contaminates, now exposed on the laminate fibers. This is done with hot water/steam equipment. This will eliminate all existing Chemical type residues, causing the Osmotic problem. (Blistering of the Hull).

Step 3. The Drying Out Period
It is extremely important to allow the hull to thoroughly dry out after cleaning. To facilitate this process you Tent the vessel with a heavy mil plastic to decrease the Dry Out Period. The tenting is accomplished by fastening the plastic approximately 18 inches above the waterline as well as laying-out plastic under the vessel and existing blocking. you seal and secure all plastic ends to the ground surfaces, and seal all loose vertical ends of the plastic tent material with shrink wrap type tape. you make the tented area as air tight as possible, creating a hermetically sealed environment.

Step 4. Moisture Level Monitoring Period
To further decrease this Dry Out Period. You install commercial dehumidifiers as well as placing calcium chloride in shallow pans on the ground surfaces inside the tented area, to absorb moisture. After approximately 20 days, a moisture meter reading is taken of the entire below waterline hull, The laminates must reach a minimum of 5-7 percent on a Sovergin Moisture Meter Scale A, for the barrier coat system to be applied. If after the 20 day moisture test, the vessel still needs drying time we replace the existing calcium chloride and continue to do so every 20 days until the desired moisture reading is obtained.

Step 5. Before Beginning The Repairs
Upon reaching a maximum moisture content of between (5 to 7) percent on the Sovergin Meter Scale A, the vessel's hull is ready for the barrier coat repair to begin.

Step 6. Repairing The Physical Damage
First you seal the entire under waterline portion of the hull with the highest quality Epoxy Resin. Then fill all blister pockets and voids with an epoxy fairing compound. When necessary apply more than one coats of the compound to fill the imperfections. Re-laminate all gross imperfections with fiberglass cloth and a compatible hull resin. After curing is complete, fairing is begun with the use of an epoxy fairing compound to make all surfaces smooth.

Step 7. Sanding Preparation
Sand and fair all compound/re-laminated areas. A general sanding of the entire hull is performed as the final step prior to the first stage/coating of the barrier coat application.

Step 8. Cleaning The Hull
Carefully vacuum clean all hull surfaces to remove dust and contaminates.

Step 9. Applying The Epoxy Barrier Protection
Apply Epoxy as an additional barrier coats. These coatings should be Hot Coated, {a method of applying the next coat over the top of the previous coat before the first coat cures and dries). Otherwise the entire hull will have to be sanded and washed with soap and water before each coat is applied. Multiple coats of Epoxy are necessary in order maintain this essential Part I barrier coat adhesion and thickness. After this stage of coating have been applied, the hull is sanded in preparation for the next series of Part II coatings.

Step 10. More Sanding & Fairing
After the barrier coats are fully cured and hardened, the hull is washed with soap and water and allowed to dry. Then the hull is sanded and faired with an 80 grit sandpaper and once again is washed thoroughly with soap-water solution. The hull should be allowed to dry thoroughly,

Step 11. Applying the Barrier Shield
Next apply a minimum of (5) coats barrier coat system. The five coats are necessary in order to maintain the essential second barrier thickness after the sanding process. Once again adhere to manufacturers Dry Time and Recoat Schedule.

Step 12. Applying The Anti-fouling Barrier
Adhering to the manufacturers Dry Time Schedule, a coat of anti-fouling paint is applied. Select a color which will be markedly different from the final anti-fouling hull color coating. This first coat of will indicate the outside layers of the System. If sanding of the hull occurs on a future date, to reduce the build-up of old anti-fouling paint coatings, the Interprotect System will not be damaged, due to this anti-fouling color indicator.
