How To Get A Proper Bathtub Liner Installation Guide And Avoid Installation Problems Or Your Bathtub Liner Will Fail! These Untold Installation Tips Will Keep Water From Getting Underneath Your Tub Liner Causing It To float!The bathtub liners installation method described in this post will guarantee the liner will not float by getting water trapped underneath and split.
You’ll want to avoid the biggest complaint with bathtub liner installation, having water trapped underneath the bathtub liner.
The water stagnates causing unsanitary condition and unpleasant odors. Over time, the hydrostatic pressure will cause the liner to split. I’ll show you how to avoid this problem.
How does water get under the liner? Poor fit and bad installation techniques are the main reason.
Many companies use generic molds that do not fit like a glove. There are over 200 different bathtub styles and many liner companies simply do not have the proper mold.
By taking 14 measurements to choose, the correct mold that forms the bathtub liner provides a perfect fit.
Here’s where the installation comes into play. Having removed 1000,s of failed bathtub liner installations, what we typically see, as the main culprits are improper surface preparation, not using butyl primer, skimping on adhesive and bad fit.
If the bathtub was refinished before, I recommend that reglazing material be chemically stripped to remove the reglazing. Should the reglazing fail, the adhesive bond with the liner will fail.
Most liner installers do not want to chemically strip because it requires proper personnel protection equipment when stripping, some will grind off some of the reglazing material and others won’t do anything.
Due to incompetence of the installer or the competitive nature of the business, a homeowner may not understand how important it is to spend the extra dollars for the time and materials for the installer too chemically strip the tub. You’re just asking the liner to fail and is a dis-service to all involved.
A Poor installations method besides not preparing the bathtubs surface is when the installer simply applies silicon caulking around the tubs perimeter and around the drain and over flow, which is pretty typical of the failed bathliner installations we see.
The next method involves only using butyl tape strips applied to the liners bottom and rail.
Both of these methods allow the liner to flex, causing the liner to separate from the wall surround and allowing water to get under the liner causing failure. Butyl tape has a very strong grip, but only if butyl primer is used.
Application of butyl primer before applying the butyl tape is critical for proper bonding to occur. Once the primer has dried; the application of butyl tape to the perimeter of the tub ¾ inch away from the wall and apply the silicon adhesive between the butyl tape and the wall.
Next Silicone adhesive applied liberally to the tubs sides, rail, outside skirt and around the drain/overflow areas.
The liner is now ready and slipped into place and by applying pressure to the liner too firmly set it. Once attached to the adhesive butyl tape, will hold the liner in place while the silicone adhesive sets up.
Now the bathtub liner installation will have the proper foundation and will not flex, providing you with years of great service.
Why; so few installers do not use the correct installation method is beyond me? Either they are incompetent or their trying to save expenses on materials.
Don’t be fooled by unscrupulous salesperson forcing you to get a wall surround with your tub liner, when you don’t need it. They push this so hard for two reasons:
- They need to have the wall surround go over the tubs perimeter lip to prevent the liner from getting water underneath it, because of their improper bathtub liner installation methods, described in this post. This locks in the tub liner, should you ever need the liner replaced, it would be impossible to pull it without destroying the walls.
- Most of these salespeople are commissioned sales and are just looking at their best interest, not yours. With proper bathtub liner installation a wall surround is completely unnecessary, unless of course you need one as well.
Now you know what to listen for when you ask them about the method they use for bathtub liner installation.
