## Questions & Answers

**Q: What is the depth?**
A: Well you could go 4 ft long 1 ft wide that would give you 1.5 ft depth  with a 4 by 7 ft liner

**Q: what type of seam tape works with this materal**
A: We did not tape any  seams but LDPE should be compatible with any tape designed for use with pond liners.  I do a lot of work with plastics and the two pieces of advice I would offer are buy a good quality, highly rated tape and wipe down any seaming locations with a proper solvent before applying tape.  I usually use a 70% or higher isopropyl alcohol to wipe down any plastics or resins that I am bonding.  It will remove any oils and release agents from the plastics and I have never found any plastics that it harms.

**Q: Can you cut it to the size you want**
A: Yes, you can cut the pond liner into any size and any shape you want.

**Q: What type or brand of seam sealer will work on this product?**
A: Personally I bought a seam sealer from the Pond Guy. But how well any sealer works depends on whether you are gluing together two liners of similar construct. This pond liner is not very flexible and rather brittle, and shiny. It did not match the rubber type liner of my current pond. Therefore, this liner did not suit my needs. I ended up pulling up this replacement liner and purchasing a small amount of proper liner from the Pond Guy, and more sealer. Don't waste your money on this liner

    Better than the Original!!
  

*by J***C on Reviewed in the United States on 6 August 2022*

We needed two patches to complete our waterfall pond. One was to cover the return hose at the rear of the waterfall and the other was a piece to help direct the water more precisely in the fountain itself. The amount we received was sufficient for our needs. It was more heavy duty and yet pliable for the job. We were very satisfied with this product for our needs.
