Finally! The Post Lizardskin Results episode. I finished the install of this spray-in insulation about three weeks prior to the recording of this podcast. I wanted to see how the Lizardskin was going to hold up and perform for both the sound insulation as well as cutting down on some of the heat in the van.
In this episode, I go into some detail on some of the lessons I learned before, during and after the application. Take heed my fellow Lizardskinners. Learn from my mistakes!
1. Don’t do it by yourself. You are going to need some help. You can manage it but an extra person that can refill you sprayer, quickly mask off an area you missed, or just remind you to drink water in the heat is a great asset.
2. Lizardskin is thick. Both the SI and CI. You are going to make a mess. Have plenty of tarps laid down and some old towels to wipe your hands and sprayer with.
3. The wet-mil gauge is just that. For product that is wet. The SI goes on thick and the CI even more so. You will want to check early and often when you get started. Once you see how the product looks going on at the recommended 20 mils, you can check less often.
4. Manage you product. I needed 8 gallons per coat for the van that I was spraying. So think about how you are going to manage that quantity. I basically thought, OK I am going to need 8 gallons for this square feet. If each bucket is 2 gallons, I will need roughly 1 for the ceiling, one for each side including one back door and I better roughly have one left to finish the floor on the way out the back.
5. Pick a pattern for each coat and repeat it for all the sprays. I did the complete ceiling first. Then the Driver side wall (easiest), Passenger side wall (most complex due to sliding door and then I started on the floor at the cab and sprayed walking backwards till I had it covered.
6. Watch your step. If you don’t, you can fall right out of the van. Seriously. Also you are going to have the compressor hose that will insist on being exactly where you do not want it.
7. Take breaks. The stuff dries quickly but not so fast that you can’t take a breather every couple of fills. It is also good to let your compressor take a short break every now and then. Mine 33 Gallon one from Husky was rated to run 30 minutes of every hour. I pushed this a bit but tried to keep it in mind.
8. Wear a mask. The SI is heavy and drops out of the air quickly. However, the CI is MUCH lighter and hangs in the air much longer. Do yourself a big favor and keep this stuff out of your lungs.
9. If you think you are done masking, you probably are a professional painter or you are completely wrong. Masking sucks. Seriously. However, you will be glad you did. Buy good quality masking tape in varying widths. Aluminum foil is your friend. It will cover wires and odd shapes when masking tape may not.
10. Think about your masking. Determine how you are going to spray a section before you fire up the sprayer. My example was the sliding door on the side of the van. There was a section at the bottom that I had thought would be sprayed. However, there was no way to get a sprayer to the area. I ended up taping a bit higher and saving myself a lot of heartache.
11. Walk your vehicle every couple of sprayer fills and look for overspray. The Lizardskin is pretty forgiving when it is wet. However, it is pretty stubborn when it has dried.
12. Have a spatula or ladle or both to help get the product out of almost empty buckets. This stuff is expensive and you have already purchased it. Use it.
13. Be ready to protect it. By some Top Coat for areas that will remain exposed. And if you are going to be doing the floor like I did in the van, have your subfloor ready to lay down over it. This stuff is not paint. It maintains a slightly rubbery texture. Don’t walk directly on it and not expect it to take a beating.
14. Wear something you really hate. I mean like a jersey of a team you hate. A crappy Christmas sweater. Whatever you are wearing will be trash. Those guys in the video make it look like a super clean application and for the most part it is but you are going to get it on you. It just happen. Bragging rights. Stay out of the wind and yes, it does pour into the sprayer easier than you would think.
15. Prepare to be amazed. I had high expectations. But I watched the videos and I read the directions. (Crazy, right?) But doing this will save you from a bad experience. Every person I spoke to at LizardSkin was awesome and friendly. Don’t decide to do this on a Friday night after a few beers and start spraying Saturday morning. Do your homework and reap the benefits.
I also discussed how I used the ZOOM H4N Audio recorder to get a baseline before the install and comparison results after the install and before anything else was done like installing the subfloors. Here is a trick. The ZOOM H4N fits really well in a phone caddy. This is how it looked from the driver’s seat.
There are several pics of the masking process and the installation in the Photo Gallery
The orange is laid directly over the top. It certainly shows the amplitude being lower. Using a comparison program in Audacity shows:
Time started = 0 hour(s), 0 minute(s), 0.00 seconds.
Time ended = 0 hour(s), 1 minute(s), 37.52 seconds.
Average RMS = -21.2 dB.
Time started = 0 hour(s), 0 minute(s), -1.00 seconds.
Time ended = 0 hour(s), 1 minute(s), 37.52 seconds.
Average RMS = -18.3 dB.
Difference = 2.9 Average RMS dB.
Check out the audio comparison in the podcast and let me know what you think. As usual, I appreciate the listens and the encouragement that quite a few people are posting and sending.
Stay in touch and keep the course.
