Application

At what speed should microcement be sanded?

Use low to medium speeds and monitor both temperature and sanding aggressiveness.

Products and Systems

Can a beginner handle the application?

Yes, on smaller and less risky areas; shower and floor are more demanding.

Application

Can Aqua Nature be diluted with water?

Dilution is possible only according to the technical datasheet and must not compromise the properties or shade.

Shades and Samples

Can Dilution of Aqua Nature Affect the Colour?

Yes, excessive or uneven dilution can affect the shade and texture.

Substrates

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.

Floors and Stairs

Can I apply microcement on an epoxy floor?

Yes, provided the epoxy is roughened, degreased and an appropriate adhesion bridge is created.

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.

Bathrooms and Showers

Can I apply microcement on Sika waterproofing?

Generally yes, after verifying compatibility; ideally with a test area and the recommended system procedure.

Floors and Stairs

Can I apply microcement on stairs?

Yes, stairs are suitable, but the edges must be well reinforced and protected.

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.

Furniture and Worktops

Can I apply microcement onto MDF?

Yes, especially for furniture; the MDF must be stable, clean, and properly primed.

Bathrooms and Showers

Can I apply microcement onto waterproofing?

Yes, but only if it is compatible and the surface allows good adhesion of the subsequent layer.

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.

Furniture and Worktops

Can I apply microcement to a fireplace?

Yes, on visible parts away from extreme temperatures; the thermal load on the substrate must be addressed.

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.

Furniture and Worktops

Can I apply microcement to a worktop?

Yes, but it must be well protected with varnish and you need to expect higher levels of wear.

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.

Furniture and Worktops

Can I apply microcement to furniture?

Yes, especially on MDF or stable plywood; edges and final protection need to be addressed.

Substrates

Can I apply microcement to plywood?

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

Floors and Stairs

Can I Use a Metal Edge on Stairs?

Yes, if it is compatible with the assembly and properly installed without sharp transitions.

Floors and Stairs

Can I use mesh tape on the edge of a stair?

Yes, but the edge must be mechanically protected and carefully finished.

Products and Systems

Can I use only Aqua Base and varnish?

Technically it is sometimes possible, but it is not a standard final decorative system.

Application

Can Microcement Be Machine Sanded?

Yes, but with care to avoid over-sanding or circular marks.

Application

Can microcement be sanded by hand?

Yes, smaller areas, corners and repairs are commonly sanded by hand.

Application

Can Primer Plus be used on a non-absorbent substrate?

Yes, but it is advisable to check the appropriate preparation and adhesion on a non-absorbent substrate.

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.
