LET’S GET STARTED
Step 1: Drilling Holes & Applying Foam Support
Start off by grabbing your basic tools: a power drill, 1/4” – 5/16” drill bits, and Floor Support Foam. Drill holes at the crack's ends and middle for even coverage using the two different drill bits. After drilling, start pumping foam into the deep holes first and then the shallow ones. Take it slow and easy, especially when dealing with foam. Too much foam can cause bulging, especially with plastic tubs, so handle it with care. Give it time, around 2 – 4 hours, for the foam to set until it's no longer gooey.
Watch out for any bulging; if it happens, add some weight on top of the area, keep an eye on the foam coming out of each hole, and let it sit for 2 - 6 hours. This patient and careful approach ensures a strong foundation to your repair.
Step 2: Prep Damaged Area
Make sure you have all the necessary tools at your fingertips: 80 grit sandpaper, vacuum, 5 ½” orbital sander, an extension cord, 3-prong splitter, and mesh tape for larger holes. Once you're equipped, start by carefully removing any excess foam and trimming or sanding down any protruding or loose damage. Then, extend your sanding around the damaged area, going about 2 inches beyond the affected part. Thoroughness is key, so after sanding make sure the sanded surface is clean using a vacuum and acetone on a paper towel. And if you're dealing with sizable holes, don't forget to apply mesh tape.
Step 3: Apply Glass Putty
For step 3, you’ll need Glass Putty and Putty Hardener, a mixing pad or cardboard, putty spreader, wooden stir stick, orbital sander, vacuum, and 80 grit sandpaper.
It’s time to mix the Glass Putty and Putty Hardener, keep a 10:1 ratio of the two products. After application, patience is key – let the Glass Putty cure for at least 30 minutes before you start the sanding process.
Pro tip: focus on achieving a smooth and feathered edge during application; it'll save you from the hassle of extensive sanding later on.
Step 4: Match Color
When it comes to achieving the perfect color for your bathtub repair, precision is key. Begin by preparing between 1 to 3 oz of mixed resin, ensuring you have an ample supply of Catalyst and Reducer on hand for the task. Start small in the color mixing process, blending modest amounts of resin until you reach the exact shade you desire.
To ensure accuracy, conduct a simple test: place a single drop of the mixture on the tub's surface, spread it evenly, and then blow dry it. This method allows you to observe the final shade once it's dried. If, by chance, the resin colors don't seamlessly match your tub, use a small amount of dye.
Step 5: Mix Coating Products
Once you’ve matched the color, mix resin, Catalyst, and Reducer in the correct ratios according to the chart provide in the instructions. Carefully pour the resin into the Preval jar, followed by the Catalyst and Reducer, and stir to create a well-blended mixture. Before applying the mixture to your repair area, test the Preval spray system to guarantee that your application will go on smoothly.
