Tile Application Guide - Floors & Walls

Tile Application Guide - Floors & Walls

This guide covers the application of Ecoflor® Micro Concrete directly over existing tiled surfaces — floors and walls — including wet areas. The tile covering system uses PrimeLock and fibreglass mesh to create a sound bonding base before the cement coats are applied.

Practice first. Before tackling your tiled surface, run through your technique on a piece of cement sheet. Tiled surfaces have specific requirements — follow this guide carefully for a professional result.

Ecoflor tile covering system diagram with PrimeLock primer layer

Option A — 600 Cement (1 coat)

One coat of 600 Cement over the primed mesh. Faster and uses fewer materials. Recommended when time is a consideration.

Option B — 300 Cement (2 coats)

Two coats of 300 Cement over the primed mesh. Builds sufficient thickness to fully cover the mesh shadow for a cleaner result.

1

Clean the tiles thoroughly

The tiles must be completely clean before any primer is applied. Remove all traces of soap scum, grease, mould, and surface contaminants using a suitable detergent. Rinse well and allow to dry completely.

  • Confirm the surface is structurally sound, without excessive cracking or moisture ingress.
  • For wet areas, confirm the presence of a sound waterproof membrane beneath the tiles before proceeding.
  • Treat floors and walls as separate panels throughout the installation.

Optional — fill grout lines: Prime grout lines with Concrete Modifier, then apply Micro Cement paste to fill them. Allow to dry 1–2 hours, then sand the entire surface with 80-grit paper and vacuum thoroughly.

2

Mask adjacent structures

Remove internal doors where applicable. Apply 50mm painter's tape along skirting, door frames, and adjacent flooring. Reinforce with 50mm cloth tape over the painter's tape. Protect all adjacent horizontal surfaces.

3

Prime — PrimeLock (first coat)

Apply the first coat of PrimeLock over the cleaned tile surface using a brush or roller. Ensure even, full coverage.

Allow to dry — approximately 3 hours.

4

Apply fibreglass mesh

While the first coat of PrimeLock is still tacky, or immediately after drying, apply adhesive-backed fibreglass mesh over the entire surface. Ensure full coverage with no gaps. Butt mesh edges together — do not overlap.

The fibreglass mesh is critical for tile covering applications — it bridges grout lines and prevents reflective cracking in the finished surface.

5

Prime — PrimeLock (second coat)

Apply a second coat of PrimeLock over the fibreglass mesh to lock it into place. Ensure the mesh is fully embedded and covered.

Allow to dry overnight before applying the base coat.

6

Base coat — 600 Cement (Option A) or 300 Cement × 2 (Option B)

Choose one of the two base coat options. Both achieve the same goal — sufficient build to cover the mesh shadow before applying Micro Cement.

Option A: 600 Cement — 1 coat

Coverage: approximately 1.3m² per kg on floors / 1.0m² per kg on walls.

Option B: 300 Cement — 2 coats

Coverage: approximately 1.6m² per kg on floors / 1.0m² per kg on walls per coat. Sand and re-prime with Concrete Modifier (diluted 20–30%) between the two coats. Allow 60 minutes drying time before applying the second coat.

Mixing ratios (both options)

Ingredient Floors (per 15KG) Walls (per 15KG) Walls (per 1KG)
Clean water 2 litres 1.6 litres ~105ml
Concrete Modifier 2 litres 1.6 litres ~105ml
Liquid Colour Pigment 200ml 200ml proportional

Mixing method (both options): Combine Concrete Modifier and water 1:1. Add the full 200ml colour pigment container to the entire liquid batch and stir until evenly combined. Then measure out the required volume of coloured liquid proportionate to the amount of cement powder you are mixing — e.g. 630ml per 3KG of 600 or 300 Cement. Gradually add the cement powder while mixing continuously. Blend for 2–3 minutes until creamy and flowing.

Only mix what you can apply within 30 minutes.

Application: Apply by trowel ensuring full, even coverage. Avoid build-up at edges and corners.

Allow each coat to dry — approximately 6–8 hours.

Important: Do not add liquid to rehydrate a stiffening mix — this will alter the colour. Remix with the paddle stirrer to soften it.

7

Sand and re-prime before finish coat

Sand the dried base coat with 80–100 grit sandpaper using an orbital sander with dust extraction. Vacuum all dust thoroughly.

Apply Ecoflor® Concrete Modifier diluted 20–30% in clean water. Allow to dry — approximately 60 minutes — before applying Micro Cement.

8

Finish coat — Micro Cement

Ecoflor® Micro Cement produces an ultra-smooth, polishable finish. Coverage: approximately 3m² per kg for both floors and walls when applied over 300 Cement.

Only mix what you can apply within 30 minutes.

Ingredient Floors (per 10KG) Walls (per 10KG)
Clean water 1.9 litres 1.6 litres
Concrete Modifier 1.9 litres 1.6 litres
Liquid Colour Pigment 200ml 200ml

Apply a thin coat by trowel ensuring full coverage. Keep the surface as smooth as possible and avoid build-up at edges and corners.

Colour mixing tip: Add the full 200ml pigment container to the entire liquid batch and stir until evenly combined. Then measure out the required volume of coloured liquid proportionate to the cement powder being mixed — e.g. 640ml per 2KG of Micro Cement on floors, or 640ml per 2KG on walls.

Allow to dry — approximately 4–6 hours.

Important: Do not add liquid to rehydrate a stiffening mix — this will alter the colour. Remix with the paddle stirrer to soften it.

9

Sand before sealing

Remove all masking tape. Use a steel spatula to knock down any dry cement build-up at edges and corners.

Sand the surface with 100–120 grit sandpaper. Vacuum all dust thoroughly before sealing.

10

Seal

Sealing is essential for durability and stain resistance. Apply sealer no earlier than 8 hours after completing the Micro Cement coat.

Floors:

Prymaren
Pre-sealer — 2 coats
Ecostar 2K
PU protectant — 2 coats

Walls:

Prymaren
Pre-sealer — 1 coat
Ecostar 2K
PU protectant — 1 coat

For wet areas or floors requiring slip resistance, add EcoGrip to the final coat of Ecostar 2K. Use flexible caulking at internal corners after sealing is complete.

Allow full cure of 7 days before normal use.

What our trade customers say

Real feedback from trade customers and Google reviews.

"I've been using Ecoflor as my supplier for micro cement projects, and they have been outstanding. The quality of the micro cement system itself is excellent, consistent, easy to work with, and the finished results have been reliably beautiful across different projects. Fabian's technical support has also been a huge asset. He's always available to answer questions, offer guidance on application techniques, and troubleshoot when needed, which has made a real difference in the quality of my work. Highly recommend Ecoflor as a supplier for anyone in the trade looking for a dependable micro cement system backed by real expertise."

Josh, Valetta Form & Design — Google review

"I've now used a few different microcement products on various jobs, and I have to say Ecoflor has been the standout for me. From the first mix it just felt easier to work with. The consistency was great, it trowelled on smoothly, and I found it much more forgiving than some of the other systems I've used. It gave me enough time to work the surface properly without feeling like I was racing against the clock. The finished floor has come up even better than I hoped. As a builder, I'm pretty fussy about the products I use because my reputation depends on the end result. Based on my experience, Ecoflor has become my preferred microcement system, and I'll definitely be using it again on future projects."

Daniel Mack, Builder — Google review

"I held off writing this for a few weeks because I wanted to make sure it wasn't just first impressions before I put my name to a recommendation, and I can honestly say the Ecoflor system is the real deal. I've worked with a lot of microcement brands, and this one's easily the best balance of quality, ease and finish I've used. Every step just makes sense. For tradies, it saves time and still looks high-end. The burn from the final sand is brilliant, and once that top coat's down, it looks like a polished job every time. The team at Ecoflor are great to deal with and always quick to help if you need advice."

"I'm a flooring contractor based in Melbourne and have been using micro toppings to rejuvenate old concrete for years. After trying numerous competitors' products without great success, we found Ecoflor and started dealing with Fab. His product is second to none. It produces great results every time and our customers are delighted with their new floors. I highly recommend Ecoflor to both people looking to renovate their floors and contractors looking for a new micro topping system to install."

Nick, Allgrind Melbourne — Google review
★★★★★

"We used Ecoflor's product for our alfresco project on a feature wall and floor area and could not be happier with the finished look and feel. Service was excellent, from communication and product knowledge through to installation by professional tradesmen. Ecoflor products come highly recommended and we'll definitely use them again in future."
