MicroCement Wall Surface (Wall Installation Guide)

Easy Application Instructions for Microcement on Internal or External Vertical Surfaces.

1. Purpose

This guide provides step-by-step instructions for applying Ecoflor® MicroConcrete to vertical surfaces, creating the appearance of Concrete Walls, Tadelakt Lime, or Venetian Plaster. This trowelled method is ideal for commercial and residential interior and exterior walls.

2. Introduction

Ecoflor® MicroConcrete VertEcol is a premium, polishable blend of lime and cement render, designed for easy application on walls. Developed in Australia, it transforms existing surfaces efficiently. The substrate must be structurally sound and appropriately prepared to ensure long-term performance.

3. Resurfacing Overview

Ecoflor® MicroConcrete VertEcol is applied over hardened surfaces. Its polymer-modified lime-cement composition allows for effortless application, making it accessible for both professionals and skilled DIYers. The key requirement is that the surface must be paint-ready before application.

4. Surface Condition Assessment

The substrate should be free of structural defects, peeling paint, or contaminants such as adhesives and sealers. Any necessary cleaning or removal of foreign materials must be completed before applying Ecoflor® MicroConcrete.

5. Panel Joint Treatment

Plasterboard or panel joints must be taped to prevent cracking.
Fibre tape is recommended for secure joint reinforcement.
Apply joint compound suitable for the panel type per building regulations.
Proper surface preparation is crucial to prevent cracks from forming post-application.

6. Equipment Requirements

Basic Tools:

High torque power drill with variable speed
Metal paddle stirrer for low-viscosity cements
Measuring jugs and mixing buckets (1L-15L capacity)
Trowels, sponge, cleaning brush
Orbital sander (120-240 grit sanding screens)
Dust extraction vacuum
Paintbrushes and microfiber rollers
Safety PPE (gloves, dust mask, goggles, work boots)

Consumables:

Masking Tape (50mm multi-purpose masking tape)
Mixing buckets

Required Products:

Ecoflor® MicroConcrete VertEcol
Ecoflor® Concrete Modifier
Ecoflor® Liquid Colour Dispersion (200ml)
Clear Coat Sealer

7. Application Process

Step 1: Mask Adjacent Structures

Remove internal doors if applicable.
Apply 50mm painter's masking tape to adjacent surfaces (architraves, skirting boards, cabinetry, etc.).
Cover adjacent flooring and horizontal surfaces with protective material.

Step 2: Surface Preparation

Ensure the wall is structurally sound, clean, and free of contaminants.
Sand surfaces with 60-80 grit sandpaper to remove loose paint and smooth imperfections.
Wash down with water and a sponge to remove residual dust.

Step 3: Apply Primer Coat

Use Ecoflor® Concrete Modifier undiluted.
Apply using a paintbrush or roller.
Allow to dry thoroughly before proceeding.

Step 4: Mixing Micro Cement

Mix Ecoflor® Concrete Modifier and water (1:1 ratio).
Add 10kg of Ecoflor® MicroConcrete VertEcol 3.4L - 3.8L of mixed liquid (modifier, water, and 200ml colour dispersion).
Use a high-torque drill with a paddle stirrer to blend into a smooth, creamy consistency.
Adjust consistency by adding small amounts of water as needed.

Step 5: First Coat Application

Wearing gloves, apply the mix using a sponge in circular motions.
Trowel over immediately to flatten and compress the surface.
Work in sections and maintain a wet edge to ensure a seamless finish.
Do not pause mid-application; having a second person assist is beneficial.

Step 6: Second Coat (Wet-on-Wet Application is optional)

Apply the second coat before the first fully dries (10-30 minutes after initial application).
Follow the same sponge and trowelling technique.
Allow to dry overnight.

Step 7: Optional Burnishing

Once the second coat has set, begin polishing.
Lightly trowel the surface at a 10-degree angle, increasing pressure as needed.
If needed, use a damp sponge or spray bottle to moisten dry areas.
For a polished finish, use a flexible steel or plastic trowel to avoid black streaks.

Step 8: Sanding (Recommended for Enhanced Finish)

Lightly sand the surface for a smooth, mottled effect.
Start with 120-grit sandpaper and progress to 180-240 grit for a higher polish.
Remove excess dust with a dry cloth before sealing.

Step 9: Apply Clear Coat Sealer
