The key advantage of HYDRO BAN is the extra heavy duty waterproofing protection it provides, making it ideal for applications that require a robust vapor barrier and waterproof membrane.

Laticrete 9235 And HYDRO BAN Comparison

Now that we’ve covered the basics of Laticrete 9235 and HYDRO BAN, let’s directly compare the two to see how they stack up against each other:

Application Method

  • Laticrete 9235 – Applied with a paint brush or roller in a thin, fluid coat.
  • HYDRO BAN – Brush, roller, or trowel applied. Can be spray applied with proper equipment.

Dry Film Thickness

  • Laticrete 9235 – 30-40 mils total over 2 coats
  • HYDRO BAN – 30 mils over 2 coats

Curing Time

  • Laticrete 9235 – Dries in 2-3 hours per coat. Flood test in 2 hours.
  • HYDRO BAN – Dries in 1-3 hours per coat. Flood test in 2 hours.

Working Time

  • Laticrete 9235 – 20-30 minute working time after mixing.
  • HYDRO BAN – 15 minute working time.

Crack Isolation

  • Laticrete 9235 – Up to 1/8″ crack isolation.
  • HYDRO BAN – Up to 1/8” crack isolation.

Suitable Substrates

  • Laticrete 9235 bonds to cement boards, concrete, masonry, wood, metal, PVC, acrylics, and more.
  • HYDRO BAN bonds to concrete, cement board, masonry, ceramic tile, glass, metal, wood, and more.

Interior vs. Exterior Use

  • Laticrete 9235 can be used for interior and exterior applications.
  • HYDRO BAN can be used for interior and exterior applications.

Freeze-Thaw Stability

  • Laticrete 9235 is freeze-thaw stable for up to 5 cycles at 0°F.
  • HYDRO BAN is freeze-thaw stable up to 3 cycles at 0°F.

Hydrostatic Pressure Resistance

  • Laticrete 9235 resists hydrostatic pressure up to 7 psi.
  • HYDRO BAN resists hydrostatic pressure over 700 psi – much higher water resistance.

VOC / Low Emitting

  • Laticrete 9235 is VOC compliant – 105 g/L.
  • HYDRO BAN is Greenguard Gold certified for low VOC emissions.


  • 10 year product warranty available for both Laticrete 9235 and HYDRO BAN.


  • Laticrete 9235 costs approximately $165 per gallon.
  • HYDRO BAN costs approximately $115 per gallon.

So in summary, HYDRO BAN has greater hydrostatic pressure resistance and is a bit more affordably priced, while Laticrete 9235 has a longer working time, higher freeze-thaw stability, and can be spray applied to potentially save time and labor costs. Both offer excellent thin film waterproofing with warranted performance.

Laticrete 9235 Or HYDRO BAN Waterproofing: Which Is Better?

Based on this comparison, which waterproofing membrane is the best choice? Here are some key factors to consider when deciding between Laticrete 9235 and HYDRO BAN:

  • Water Exposure Level

For high water exposure areas with direct water contact or high hydrostatic pressure, HYDRO BAN is the better choice given its incredibly high 700+ psi water resistance. For lower-pressure water exposure like showers and tub surrounds, either membrane will work well.

  • Crack Isolation Needs

Both membranes provide effective crack isolation up to 1/8”. If you only need basic thin crack isolation, 9235 and HYDRO BAN are equal. For projects with greater movement, consider a thicker crack isolation membrane.

  • Environmental Factors

In hot or cold climates, Laticrete 9235 may be a better choice given its slightly wider application temperature range and higher freeze-thaw stability. HYDRO BAN can still be used in many exterior applications but may need extra care.

  • Substrate Type

Check that the membrane is approved and warranted for your specific substrate. In general, both bond well to the most common materials.

  • Application Method

If spray applying to save time, Laticrete 9235 is the only choice. For roller, brush, or trowel application, both work well.

  • Cost

If budget is a concern, the lower cost of HYDRO BAN may make it more appealing, though the cost per square foot is still low for both options.

  • Project Size

For larger commercial projects, HYDRO BAN comes in 5 gallon pails to help speed up application. Laticrete 9235 is sold in 1 gallon containers.

  • Warranty Requirements

To get the 10 year product warranty, approved installers and methods must be used for both membranes. Ensure the warranty meets your needs.
