Can I apply microcement on a Cetris board?

Yes, provided the boards are firmly fixed and the joints are properly reinforced.

Substrates

Can I apply microcement on a lime-cement plaster?

Yes, provided the plaster is solid, matured, dust-free and not painted with a non-adherent coating.

Substrates

Can I apply microcement on a self-levelling screed?

Yes, if the screed is solid, cohesive, dust-free and properly primed.

Substrates

Can I apply microcement on concrete?

Yes, concrete is a suitable substrate if it is matured, strong, dry and clean.

Substrates

Can I apply microcement on Fermacell?

Yes, Fermacell is a suitable substrate with proper preparation and reinforcement of joints.

Substrates

Can I apply microcement on gypsum plaster?

Yes, in a dry interior, if it is stable, dry and properly primed.

Substrates

Can I apply microcement on impregnated plasterboard?

Yes, provided the structure is stable and the surface is properly prepared and primed.

Substrates

Can I apply microcement on OSB boards?

Yes, but the OSB must be firmly fixed, stable and usually reinforced with a reinforcing layer.

Substrates

Can I apply microcement on plasterboard?

Yes, but a solid structure and full-surface reinforcement with reinforcing mesh is recommended.

Substrates

Can I apply microcement on sand-blasted epoxy?

Yes, sand-blasted epoxy is generally a suitable mechanical substrate if it is solid and free of loose sand.

Substrates

Can I apply microcement on tiles without demolition?

Yes, if the tiles are stable, cohesive, degreased, and free of hollow spots.

Substrates

Can I apply microcement on tiles?

Yes, the procedure is similar to that for floor tiles; the key factors are strength, degreasing, and a reinforcement layer.

Substrates

Can I apply microcement on Venetian plaster?

Only after verifying adhesion; glossy or waxed plaster must be removed or roughened.

Substrates

Can I apply microcement on Ytong?

Yes, but Ytong is absorbent and must be levelled, reinforced and properly primed.

Substrates

Can I apply microcement over adhesive with mesh?

Yes, provided the layer is even, solid, fully cured and dust-free.

Substrates

Can I apply microcement over anhydrite?

Yes, provided the anhydrite is dry, sanded, vacuumed and properly primed.

Substrates

Can I apply microcement over existing microcement?

Yes, provided the original surface is solid, cohesive, degreased and sanded down.

Substrates

Can I apply microcement to a kitchen splashback?

Yes, it is a suitable application if the surface is finally protected with a durable lacquer.

Substrates

Can I apply microcement to an chipboard panel?

Only with caution and rather on less stressed elements; the panel must be stable and protected against moisture.

Substrates

Can I apply microcement to plywood?

Yes, it is possible on stable plywood, but edges and joints must be properly treated.

Substrates

Do I Have to Remove Old Tiles?

No, if they are solid, cohesive and free of hollow spots.

Substrates

Do I have to remove the old tiling?

No, if it is firmly fixed and properly prepared.

Substrates

How Can I Identify Hollow Tiles?

By tapping; a hollow tile produces a different, more hollow sound and needs to be repaired or removed.

Substrates

How do I know if the substrate is sufficiently strong?

The substrate must not crumble, peel, dust or sound hollow.

Substrates

How Large Imperfections Does Microcement Cover?

Microcement follows the substrate; larger imperfections need to be levelled beforehand.

Substrates

How to Degrease the Substrate?

Use an appropriate degreaser, rinse with clean water and allow the surface to dry.

Substrates

How to Prepare a Wall Surface?

The wall must be flat, cohesive, and free from grease, dust, and unstable coatings.

Substrates

How to Prepare the Substrate in a Shower?

The substrate must be solid, even, waterproof and ready for the application of the screed system.

Substrates

How to prepare the substrate on the floor?

The floor must be flat, stable, dry, dust-free and without any loose parts.

Substrates

How to prepare tiles before application?

Tiles must be degreased, roughened as needed, checked for hollow spots and treated with a reinforcement layer.

Substrates

How to prepare tiles before application?

Tiles are cleaned, degreased, inspected and covered with a basic reinforcing layer.

Substrates

Is a reinforcing mesh necessary?

In most high-risk substrates, yes, especially on tiles, claddings, panels and joints.

Substrates

When is Reinforcing Mesh Necessary?

When overlapping joints, board materials, substrates at risk of movement, and in bathrooms.

Substrates

Which Reinforcement Mesh to Use?

Use a glass fibre reinforcement mesh suitable for trowel-applied systems.
