Overview

Rasolastik ADV is a two-part cement-based waterproofing membrane designed for floors and walls in both interior and exterior areas. Once mixed, it forms a flexible coating that handles movement and ongoing moisture exposure. Commonly used across bathrooms, balconies, and tiled wet areas where a stable waterproof layer is needed before tiling.

Key Features

Two-component system with powder and liquid mix
Flexible membrane suited for movement-prone substrates
Works across interior and exterior applications
Suitable for bathrooms, balconies, terraces, and pools
Can be applied by brush, roller, or spray
Forms a tile-ready surface once cured

Where to Use It

Used in areas exposed to regular moisture or weather. This includes bathrooms, showers, balconies, terraces, and pool surrounds. Also used when upgrading older surfaces where waterproofing needs to be added without full removal.

How to Use It

Make sure the surface is clean, solid, and free from dust or loose material. Prime if required based on the substrate. Mix Component A and Component B to the recommended ratio until consistent. Apply the first coat evenly, allow it to settle, then apply a second coat to build a continuous membrane. Let it cure fully before tiling.

Compatible Substrate

Concrete
Cement screeds
Cement plaster
Cement-lime mortar
Existing ceramic tiles
Plasterboard (with primer)

Appearance

Component A: Grey powder
Component B: White liquid
Mixed product: Smooth, spreadable membrane

Pro Tip

At joints, corners, and floor to wall transitions, use reinforcing tape along with the membrane. These are the areas where movement shows up first, so a bit of extra build here helps avoid failures later.
