Frequently Asked Questions

Is Microcement waterproof?

Here at Cementtec we use the industry's leading Microcement brand Forcrete, which is fully waterproof during every layer of the application process. Two layers of sealers are also applied. Creating a sacrificial layer which adds advanced protection.

Other Microcement brands only become waterproof once the sealers have been applied. Which means dark spots, stains and installation delays are highly likely.

Is Microcement scratch proof?

Although Microcement is extremely hard wearing. Like any finished floor, dragging heavy furniture across Microcement surfaces can cause scratches. Sharp items and point loading should always be avoided. Do not drag heavy furniture or appliances across Microcement surfaces. We recommend using felt or rubber pads on furniture such as chairs and tables, or anything which is regularly moved.

Can cracks be prevented?

We take every measure possible to repair and reinforce any existing cracks prior to the installation of Microcement. However, we cannot guarantee against any cracks that form in the substrate after our coatings are applied.

Is Microcement compatible with Underfloor heating?

Yes! Please continue to Preparation & Installation for more information.

How do I prepare my new underfloor heating system?

When commissioning a new underfloor heating system, the temperature should be brought up slowly over a period of days. A maximum of 3°C increase per day.

Once your underfloor heating system has reached your optimal temperature, we recommended turning the system off and allowing it to cool before switching it back on.

This allows the screed to expand and contract and will reveal any cracks which can be repaired prior to installation. Your underfloor heating system must be on for a minimum of 2 weeks prior to the installation of Microcement. Coating the floors before the screed has been allowed to expand and contract can cause unwanted movement.

Do I need to turn the underfloor heating off during the installation process?

No, your heating system needs to remain on. With a temperature of around 16°C. This can vary depending on environment & weather conditions.

Does Microcement need to cure?

Yes! This is a crucial stage and must be followed to ensure your surfaces remain in excellent condition. Extra protective care should be undertaken for at least 30 days after installation. Although our polyurethane sealers will be touch dry, during the colder months they can take up to 30 days to fully harden and cure. 

Do not drag or drop heavy furniture or appliances across Microcement surfaces. Sharp items and point loading should always be avoided.

Finished surfaces should be protected using boards and heavy fabric sheets. Kitchen fitters need to take extra precautions not to drag or drop heavy cabinets.

How soon can I use my new Microcement surface?

Your Microcement surface will be ready to use 12 hours after the final sealers have been applied. Please ensure you follow the curing guidelines above.

Can Microcement stain?

To avoid soiling of the polyurethane sealers, a periodic cleaning schedule should be undertaken. Strong dyes and pigments such as: hair dyes and fake tanning products should never come in to contact with Microcement surfaces. Forcrete-Stain Remover is available to purchase on particularly stubborn stains.

Can you install Microcement on to new screed

Yes! Newly installed screed floors are an ideal surface to apply Microcement if laid correctly.

Different screeds come with different drying times. You should always refer to your installer, who will be able to provide an estimated time frame based on the product type and depth.

If in doubt, check the product data sheet.

Example: An Anhydrite screed with an 80mm depth will take approximately 100 days to fully dry before any preparation work can begin.

How will I know when my screed is dry?

We will arrange a convenient time to visit the project site. Whilst there we will conduct several damp meter readings across multiple areas of the floor. By following the manufactures guidelines, we can estimate an approximate time frame in which the floor can be tested. We do this by running a damp meter reader across multiple areas of the screed. The highest reading will be taken until all tests are on or below the recommended percentage. Which varies depending on the type of screed.

What is Laitance removal and should I have it done?

Laitance is a weak layer of fine particles which rise to the surface of the screed as the anhydrite cures. Laitance should be removed between 7-14 days after the screed is laid which also helps to reduce drying times.

The majority of screed suppliers will offer laitance removal as standard, but its always worth asking the question.

Will the room need to be clear for the installation?

Yes, all furniture needs to be completely removed. The room must remain clear for the full duration of the installation process and at least 24 hours post completion.

Do you offer crack repairs?

Yes! Crack repairs are another crucial process to the application of Microcement. If left untreated, the cracks can worsen over time. Causing the top surface to crack.

Will you grind the floor first?

Yes, during the multilayer system. Floor grinding is another key process. Used to remove floor imperfections and create a strong key for each product to adhere to.

Do I need to remove Doors, Skirtings & Architraves?

We use large heavy industrial floor grinders and hoovers. Which is why we ask that doors are removed prior to our arrival.

If being replaced, skirting boards & architraves should be fitted after the installation of Microcement. However, if you’d like to keep your existing fixtures that’s fine too! But they may need a repaint after.

How do I clean Microcement?

Strictly no harsh abrasive cleaners. Forcrete Cleaner & Renovator can be purchased from Forcrete.co.uk or simply use natural plant-based cleaners. (We use “The Pink Stuff” available to purchase in Home Bargains & B&M for difficult stain removal. You will also receive a complimentary Miracle paste pot on completion of your project)

Are there any products I should avoid?

Strictly no bleach or abrasive chemicals.

Can I use a steam mop?

We do not recommend using steam mops on Microcement surfaces. At the risk of removing the protective sealers which could leave your surfaces vulnerable to stains.
