Keeping water out of a roof, shower, or wet area starts with the right waterproofing layer. The four products here take different approaches: one is a heavy EPDM rubber sheet, another is a latex bonding adhesive, and two are membrane rolls meant for tile and shower coverage. Prices range from $63.50 to $170.00, a spread of $106.50, so the challenge is matching the material to the job rather than choosing the cheapest option.
Quick Take
If you need a large rubber barrier for a roof, RV, or pond, the Uimoso EPDM roll at $139.99 gives you 150 square feet of 45-mil black rubber. If you are preparing a tile shower or bathroom floor, the Shower 20 Mil PE membrane is the lowest-priced option at $63.50 with 108 square feet of underlayment. Need to bond EPDM or TPO rubber to roofing insulation? The TEGO latex bonding adhesive at $170.00 is built for that. For a red fabric membrane that suits tile, the REDGARD roll at $87.99 also delivers 108 square feet.
Listed Price Comparison

|---|---|---|
| Uimoso 10 x 15 ft EPDM Rubber Roll | USD 139.99 | |
| TEGO 1 - 4 gal Latex EPDM and TPO Bonding Adhesive | USD 170.00 | |

Decision Matrix
- Roof, RV, or pond surface: Uimoso EPDM rubber roll - a 45-mil rubber sheet for continuous large-area coverage.
- Bonding EPDM or TPO to a substrate: TEGO latex bonding adhesive - an adhesive that helps rubber roofing stick to insulation or substrate.
- Tile and masonry waterproofing: REDGARD fabric membrane - a red fabric roll described as suitable for all tile.
- Shower walls, bathroom floors, steam rooms, and wet areas: Shower 20 Mil PE membrane - a tile underlayment with vapor barrier.
Product Notes
Uimoso 10 x 15 ft EPDM Rubber Roll
This is the large-area choice in the group. The black EPDM sheet measures 10 by 15 feet, giving 150 square feet of synthetic rubber at 45 mil thick. It is a heavy roll at 39.68 lbs, so it is built for covering roofs, RVs, and ponds more than for tight indoor spaces. The material is flexible enough to conform to roof contours, which makes installation less labor-intensive. The main planning point is that this is just the membrane; if you are adhering it to a roofing substrate, you would use a bonding adhesive such as the TEGO product to complete the assembly. When you need broad, continuous waterproofing in one piece, this is the product to consider.
TEGO 1 - 4 gal Latex EPDM and TPO Bonding Adhesive
This is not a membrane roll; it is the latex bonding adhesive used to help EPDM or TPO rubber stick to roofing insulation or substrate. The title lists a 1 to 4 gallon size, so you can choose the amount that fits your project. It serves a completely different role from the other products: it is the glue between a rubber membrane and the surface underneath. If you are installing an EPDM roof, this adhesive pairs with the Uimoso or a similar rubber sheet. The limitation is that it does not supply surface waterproofing by itself; it is the bonding layer, not the barrier. You still need a membrane to provide the waterproofing.
REDGARD Fabric Membrane 108 sq Ft (1 Roll) Red Waterproof-Suitable for all tile
This red fabric membrane is described as suitable for all tile, making it a versatile pick for tile floors, walls, and other tiled surfaces. The single roll covers 108 square feet, and the red color helps you see where the membrane is in place. Since it is a fabric membrane rather than a rubber sheet, it is not intended for the same heavy-duty roof or pond duties as the EPDM roll. For a tile project, it provides a waterproofing layer under the tile. The main thing to plan around is that it is a fabric membrane, so you will still need to integrate it with your tile-setting materials and any waterproofing system you use.
Shower 20 Mil Shower Waterproofing Membrane 3.3 Ft X 33 Ft Roll (108 Sq.Ft) - PE
This is the tile-focused option: a 20 mil polyethylene membrane with a reinforced core and dual non-woven fabric layers, designed as a tile underlayment with a vapor barrier. It is specifically described for shower walls, bathroom floors, steam rooms, and wet areas. The roll is 3.3 feet wide and 33 feet long, covering 108 square feet. It is the lighter-duty of the group in terms of membrane thickness, but that suits its purpose as an interior vapor and waterproofing layer. The limitation is that it is not meant for roof or pond exposure; it is an indoor tile underlayment. If your project is a shower or wet room, this membrane is built for that use.
Final Recommendation
- For a large roof, RV, or pond surface, the Uimoso EPDM roll is the straightforward pick thanks to its thick rubber sheet and big coverage.
- For bonding EPDM or TPO rubber to a roof substrate, the TEGO latex adhesive is the pair for that job.
- For tile and masonry surfaces, the REDGARD fabric membrane gives you a red, tile-ready waterproofing roll.
- For shower walls, bathroom floors, steam rooms, and wet areas, the Shower 20 Mil PE membrane is the purpose-built tile underlayment.
Start with the surface you need to protect. If it is a broad exterior rubber barrier, choose the EPDM sheet. If it is interior tile and vapor protection, the PE membrane is the right direction.
