Scratch protection

Even if you buy the best quality pool, finding an easy solution to the scratch problem can be difficult. Scratches can happen for a bunch of reasons, especially if you are not careful. 

Your kid, pet, or anything sharp can scratch the pool, making it look older than it really is. The only way to remove scratches is by adding a protective layer on top. 

Mold and Mildew prevention

Some underlayments like pool pads and modified clothes offer protection from mold and mildew. To be exact, the fungus makes your pool ground look odd and unattractive. 

As the pool contains water, the dark and moist underpart of the pool makes a great thriving place for them. Then again, they can cause allergic reactions with direct skin contact. 

If you don’t want to do the effort of anti-fungal spray, use a permanent underlayment solution. 

Easy cleaning

When there is an extra layer under the pool, you can just clean it instead of cleaning the true under part. Additionally, carpets or clothes can be reused for years until they meet their service life. 

Turns out, your wife will finally stop whining for you not cleaning the pool’s dirty floor. Amazing right? 

No damage from insects

Insects may burrow into your pool under part and bloom a family there. As we all know, they can damage anything, starting from your clothes to your favorite leather jacket. If you don’t want any insect-related damage to your pool, use a Pad for above-ground pools or tough, rubbery material. 

Materials to put under the above ground pool

Deciding what to put under your pool is a hard decision for the newbies. But hey, we are here, aren’t we? Here is the list of materials you can use under your pool with the best of both worlds. So, let us begin.

Foam Tiles

Ground Cloth
