How to Recoat Your Pool Slide
Why Pool Slides Go Bad - Hydro Static Water Pressure...
Rock Pool Slides have two enemies UV rays. (The Sun) and water pressure from inside the rock slide (Hydro Static Water Pressure) I have seen hydro static water pressure just blow off the best epoxy coatings money can buy in less than a year (pond armor).
When your rock slide starts feeling like a cheese grader and destroys your best swim wear you start looking for another supper slide coating. Just read the blogs about this subject the only honest conclusion you can draw from all the blogs is nothing works long term. Nothing could be further from the truth.
Just ask yourself why do new rock slides last all summer and start falling apart in the winter? The true answer is ground water working its way up through the rock that water needs to get out and the symptoms of that is paint blowing off your waterfall and Jacuzzi and your pool slide starts cracking.
This is the exact reason all rock pool slide coatings are doomed to fail. So what is the answer? Stop the hydro static water pressure from reaching the surface and that is accomplished by hardening the cement and water proofing the outer 4’’ of your rock pool slide.
Rock Pool Slide Restoration - How To Just Do It!
The first step is remove the old rock pool slide coating I use a sand blaster, For you die-hard DIY people start sanding or use a strong paint stripper and a 4000 PSI. pressure washer. Your goal is to get down to the raw concrete.
Next I sand the entire slide with 60 grit sandpaper. Your goal here is to smooth the slide (every crack has a ridge) really take your time for a smooth ride.
Next you want to make sure the slide is 100% dry so if you power washed the old coating off STOP and let it dry a couple days.
Next it is time to densifie and waterproof the slide with (foundation armor) I added their link at the bottom. Get a pump-up garden sprayer with a fan tip, spray a good coat on the slide and let it dry two hours. Next spray another coat, you are stacking the protection, let that dry an hour then mist one last coat let that sit 15 min and last mist it one more time with water this works as an activator.
How this sealer works is it penetrates deeply into the slide turns into a gel that gel gets hard and forms a waterproof shield inside the slide that stops hydro static water pressure. You just put an end to why your slide goes bad.
Next it's time to add a color coat for this use pond armor, Follow my instructions well and you will not have a problem and I will put a link for this as well at the bottom. Pick a color I use gray or tan. Start your project early or late in the afternoon you do not want to attempt this in direct sun light. Get rubber water shoes like you use jet skiing! This helps not falling off the slide. Go to home depot and get some plastic cups in the paint department along with a small roller for oil based paints and get a few extra heads as well.
TIP- When you're at home depot pick up some painters duct tape as well, this is to define the top edge of the slide Nothing looks worse than a sloppy crooked coating.
Now mix only enough pond armor to last you 10 min. You want to start at the bottom and work your way up, TIP- walk down the slide first and make sure you're not going to slide off If the slide seems too steep tie a rope to yourself and have somebody really strong holding on, (I have to do it this way all the time) Now that you are safe as can be pour pond armor in the center of the slide and roll it out smooth and just keep this process going until you are done.
The very last tip is let the pond armor 100% dry and go over every square inch of your slide with your hand looking for sharp points and sand them down epoxy is hard and the points will tear you up.
Here is the big question; do I really think this is a DIY project? The simple answer is NO, but every rock pool slide blog I look at people are going crazy trying to figure this problem out so I made this web page for all the hard core Do It Yourself enthusiasts. ENJOY
