How to Choose Waterproofing Materials: A Practical Guide

Waterproofing is the foundation that protects even the highest-quality renovation from becoming vulnerable. Invisible but essential, it shields structures from moisture, mold, deformation, and premature wear. The question "which waterproofing materials to choose" arises for both professionals and private homeowners. Let’s explore what to consider and what the modern market offers.

Types of Waterproofing Materials: From Mastics to Membranes

When choosing waterproofing, it's important to consider the application area, surface type, and operating conditions. The itum.ua catalog features the following key categories:

  • Liquid membranes (e.g., ISOFLEX-PU, ITUM Polymers, Maris, Polyval, Pazkar) — ideal for roofs, balconies, and terraces. They create an elastic waterproof coating resistant to UV and mechanical stress.
  • Mastics — single- and two-component mixtures based on polyurethane, bitumen, or acrylic. Suitable for floors, bathrooms, plinths, and foundations. Easy to apply with good adhesion.
  • Epoxy and polyurethane primers — serve as a base for waterproofing systems, enhancing adhesion and strengthening the surface.
  • Penetrating and cement-based compounds — used for basements, walls, concrete tanks, and other mineral substrates. They provide deep moisture protection.

Area-Specific Waterproofing: What to Choose for Each Case

Waterproofing materials for bathrooms: what to choose?

For bathroom floors and walls, optimal solutions include:

  • mastics (bitumen-polymer, polyurethane),
  • liquid membranes,
  • primers and seam sealants.

They’re easy to apply, resistant to constant humidity, and serve as a solid base for tiling.

If you plan to lay tile over waterproofing, check out the article Subtleties of Working with 3200×1600 mm Porcelain Slabs — it will help avoid mistakes and account for crucial nuances when working over waterproof layers.

Waterproofing for roofs: what works best?

For exposed surfaces (roofs, balconies, terraces), key qualities include:

  • UV and temperature resistance,
  • high elasticity,
  • durability.

Top choices are ISOFLEX polyurethane liquid membranes, mastics by Maris and Polyval, and polyurethane sealants.

Foundations and plinths

Here, protection from groundwater is critical. It’s best to:

  • use penetrating cement-based mixtures,
  • apply mastic in two layers,
  • reinforce joints with primers.

Key Considerations: Practical Tips

If you're unsure how to choose waterproofing materials, pay attention to:

  • surface type (concrete, metal, wood),
  • load level (pedestrian vs technical zone),
  • application method (brush, roller, trowel, spraying),
  • reinforcement possibility (some mastics can be strengthened with mesh),
  • budget and expected service life.

Which Waterproofing Materials Are Most Effective

There’s no universal answer to "what is the best waterproofing material" — it all depends on the task. However, experts recommend:

  • Polyurethane mastics and membranes — for roofs and terraces,
  • Cementitious mixtures — for foundations and basements,
  • Epoxy primers — under porcelain, flooring, and complex designs,
  • Combined systems — e.g., primer + mastic + mesh reinforcement — for high-stress areas.

If you're working on facades and combining waterproofing with decorative materials, check out the article Porcelain Stoneware in Facade Finishing — it offers tips for blending protection with aesthetics.

Why It’s Worth Checking out itum.ua

At itum.ua you’ll find a wide selection of waterproofing materials:

  • mastics (including ITUM Polymers, Pazkar, Maris),
  • liquid membranes,
  • polyurethane sealants and primers,
  • penetrating and cement-based mixtures for foundations and tanks.

We’ll help you find the optimal solution for your conditions, volume, and budget — no pressure, just expert support.

Summary: Confident Choices for Every Project

If you're asking "what waterproofing material should I choose", focus first on usage conditions and base quality. For bathrooms — mastic, for roofs — membrane, for foundations — cementitious compound.
