MicroCement Flooring Surface (Floor Installation Guide)

This guide is intended to provide basic instructions for the application of Ecoflor® MicroConcrete to simulate a Burnished Concrete Floor, Polished or with a raw industrial look. A three-dimensional surface that reflects both the light and dark shades of the same colour. A trowelled method used on existing flooring surfaces on internal or external flooring, and other horizontal surfaces such as benches, stair treads and landings in commercial and residential buildings.

Ecoflor® MicroConcrete Flooring System includes a white cementitious base coat; 600 Cement, a white cementitious 2nd coat; 300 Cement, and a white micro-fine polishable cementitious finish coat; Micro Cement, for trowel application on interior flooring surfaces. The white cementitious materials may be coloured during the application using Ecoflor® Liquid Colour Pigments. Developed in Australia by Concrete Services Group Pty Ltd as an economical alternative to transform existing plain surfaces. The surface on which Ecoflor® MicroConcrete is to be used must be structurally sound and should only be selected based on suitable conditions to provide an acceptable surface which will aid the serviceability of the resurfacing system during its design life. 

Ecoflor® MicroConcrete coating system is 1mm – 2mm thick and applied on existing hardened surfaces, such as existing floors. The cementitious based polymer modified cement blend, has been designed for absolute ease of application. A professional flooring expert is not needed to install it, anyone good with a trowel or competent at DIY could easily give it a go.

The most important thing to remember is that the surface to which you are going to apply the Ecoflor® MicroConcrete Flooring System has undergone proper preparation and has floor design in place.

Ecoflor® MicroConcrete can be applied to most flooring substrates including Concrete, FC Sheet, Chipboard Panels and Tiles. Each of these substrates have their own preparation method, which need to be followed for each individual substrate type. This guide solely covers the application process of installing Ecoflor® MicroConcrete to the properly prepared substate and does not cover the preparation methods for each individual substrate type. (Acceptable substrates are cleaned or ground concrete or newly placed cementitious levelling compound)

The existing substrate needs to be structurally sound without unacceptable cracking or stepping between the panels and without obvious defects such as Concrete Spalling or laitance (a soft powdery surface) likely to affect serviceability or design life expectations of the Ecoflor® Micro Concrete Flooring System. Existing foreign matter such as tile or vinyl adhesives on floors, paint or sealer compounds must be capable of being completely removed and the surface must be capable of being completely and thoroughly clean of contaminants before acceptance of the Ecoflor® MicroConcrete resurfacing method.

All surfaces must be clean, structurally sound and free of dust, moisture, oils and other surface contaminants. Clean concrete and other types of cementitious surfaces are best for the application of Ecoflor® MicroConcrete, Seek technical advice from Ecoflor®.

Dismantle internal doors and remove from the area, if applicable.

Apply 50mm painter’s grade masking tape along adjacent vertical surfaces eg. Architraves, skirting boards, kitchen joinery, slide door rails and horizontally on adjacent flooring. Ensure that masking is applied flat and pushed neatly into internal corners. Follow by applying 50mm cloth tape (high strength) directly over the top of the Painter’s grade masking tape. Cover and protect any other horizontal surfaces.

Use Ecoflor® Concrete Modifier mixed with 20% - 30% clean water. Apply to the surface with a brush or roller. 

Spread evenly with a full coverage. Broom application is best in a circular motion. Do not allow to pool. Let it thoroughly dry. 

The intended purpose of Ecoflor® 600 Cement with coarse aggregate is to produce a tough surface. It is applied as the base coat with a trowel method. Using this method, a 15KG bucket of 600 Cement can cover well over 20m2 or 1.3m2 per kilogram. Only mix enough 600 Cement that can be comfortably trowelled out and applied in around 30 minutes. On warmer days this time is reduced.

1st mix the Concrete Modifier with water 1:1 or 50/50

Mix ratio of water and modifier for 15kg of Ecoflor® 600 Cement -1.8 litres of Water mixed with 1.8 litres of Ecoflor® Concrete Modifier. Mix the water and modifier and lightly blend. Shake well your Liquid Colour Pigment and add to the water and Concrete Modifier mix (Use 1 premeasured 200ml container of Liquid Colour Pigment per each 15kg bucket of Ecoflor® 600 Cement

Slowly add 15kg Ecoflor® 600 Cement powder whilst continuing to mix (using your High Torque Power Drill with Metal Paddle Stirrer) 

Continually blend the mix while adding the Ecoflor® 600 Cement powder until a creamy mix is achieved. Scrape the sides of the bucket to remove any unmixed dry powder and increase the mixing speed to blend any unmixed cement. Mix consistency should achieve a state of flow that can be readily trowelled and spread evenly on to the floor. We recommend applying to whole floor at one time, so mix enough for that area using the ratios provided. If you are not mixing the whole 15kg, use about 250ml of your liquid which you have mixed (Concrete Modifier, water & colour) per kilogram of powder, get a consistency that works well with your tools and environment. 1kg should cover around 1.3m2 if applied at 0.6mm thick.

Apply the mixed material to the floor using the preferred application tools ensuring complete coverage of the area and uniform thickness. Trowel flat any ridges and use a random trowel pattern (not radial motion) as the trowel pattern may become visible upon completion. Avoid any unnecessary build up particularly along edges and internal corners.

Allow to completely dry.

Special Precautions: Mixing processes and application procedures will require modification on days of high ambient temperatures and/ or low humidity and general difference in environmental conditions between summertime and wintertime.

Technical advice from Ecoflor® about product precautions and limitations and control of workmanship procedures in such conditions is recommended.

Using a floor sander or scrubbing machine with a sanding screen attachment and dust extraction. Sand over the whole floor (dried base coat) with 80-100 grit sandpaper to remove superfluous knobs and excrescences. Hand tools will be required to sand small areas and along edges and corners.

Sanding method will vary depending on the size of the job.

E.G a small area can be sanded with an orbital sander or with a handheld sander block.

Vacuum and Repeat Step 3 - Use Ecoflor® Concrete Modifier mixed with 20% - 30% clean water. Apply to the surface with a brush or roller. 

Spread evenly with a full coverage. Broom application is best in a circular motion. Do not allow to pool. Let it thoroughly dry.

The intended purpose of the Ecoflor® 300 Cement with superfine aggregate is to produce a smoother surface. It is applied to the base coat in a thin coat with a trowel method. Using this method, a 15KG bucket of 300 Cement can cover well over 20m2 or 1.3m2 per kilogram. Only mix enough 300 Cement that can be comfortably trowelled out and applied in around 30 minutes. On warmer days this time is reduced. 

Apply 300 Cement by trowel on method. We recommend a thin trowel application for the second coat to limit visible surface imperfections and trowel lines.

1st mix the Concrete Modifier with water 1:1 or 50/50

Mix ratio of water and Concrete Modifier for 15kg of Ecoflor® 300 Cement -1.8 litres of Water mixed with 1.8 litres of Ecoflor® Concrete Modifier. Mix the water and modifier and lightly blend.

Shake well your Liquid Colour Pigment and add to the water and Concrete Modifier mix (Use 1 premeasured 200ml container per each 15kg bucket of Ecoflor® 300 Cement.

Slowly add 15kg Ecoflor® 300 Cement powder whilst continuing to mix as before. Apply to the surface as before and allow to dry. 

1kg should cover around 1.3m2 if applied thin.

Repeat step 5. Include sanding and priming as before and allow to fully dry.

The intended purpose of the Ecoflor® Micro Cement is to produce an ultra-smooth surface. It is applied to the base coat in a thin coat with a trowel method. Using this method, a 10KG bucket of Finish Coat can cover well over 30m2 or 3m2 per 1Kilo. Only mix enough Micro Cement that can be comfortably trowelled out and applied in around 30 minutes. On warmer days this time is reduced. 

Apply Micro Cement by trowel on method. We recommend a thin trowel application for the final coat to limit visible surface imperfections.

Mix Micro Cement – 1.5 litres of water to 1.5 litres of Ecoflor® Concrete Modifier and lightly blend then add the 200ml Liquid Colour Pigment and mix well as before. Slowly add 10kg Ecoflor® Micro Cement.

Continually blend the mix while adding the Micro Cement. Mix consistency should achieve a state of flow that can be readily trowelled onto the surface. 

Apply the mixed Micro Cement to the floor using the steel trowels, ensuring complete coverage of the area and trowel on tightly avoiding surface texture. Avoid any unnecessary build up particularly along edges and internal corners.

Allow to dry.
