Touching Up Microcement

Microcement is very strong and resilient, and gets stronger all the time, so chips and cracks are rarely an issue.  But if you do need to touch it up for any reason, then this guide will tell you all you need to know.

Touching Up Microcement Surfaces

We’re talking small touch ups here, not large trowel-fulls.  Microcement is notoriously difficult to patch, and almost impossible to do seamlessly. Touch ups are intended to take your eye off an imperfection, but don’t expect a seamless repair, as that is very difficult to achieve.

Larger repairs to microcement surfaces, are covered in the following guides:

Follow the directions below to complete small touch ups to microcement surfaces.

Prepare the Area

Remove any loose material and make sure the area that you are going to touch up is clean, dry and free from dust and debris.  You can tidy up rough edges by gently sanding them (try a 120 or 220 grit silicone carbide sanding disc).

Which Microcement to Use?

It’s best to use the same microcement & colour that you used initially.  If you have any left over from the original install, that would be ideal, because of the natural minerals in microcement, the colour may vary slightly between batches.

If you don’t have any of the microcement left over, or you’re not sure what you had originally, then get in touch & we can help to figure out the best way forward.

Applying the Microcement

Less is more when it comes to touching up microcement.

It will be very difficult to completely hide the imperfection and the colour match is unlikely to be exact because of the natural minerals in the products.

So rather than making the chip or crack disappear, you are aiming to make it stand out less.

With this in mind, dab or scrape small amounts of product into the crack or chip using a sponge or paint brush.

Remove as much of the excess as you can with a scraper or sponge before leaving it to dry.  Try to gently feather the new product into the original surface to minimise the join.

The microcement may occasionally sink into cracks as it dries.  If this happens, you can apply more coats until you are happy with the appearance.

Leave the microcement to dry before gently sandling the surface to blend it in more with the surrounding microcement.

Re-Seal

To ensure longevity & cohesion with the original install, you will need to re-apply the sealers.  Again, it’s best to use the same sealers that you did on the original installation.

Use a small roller to apply the sealer evenly over any exposed microcement. Don’t put any pressure on the roller and try to feather it out around the edges to avoid leaving roller marks in the surface.

Mix & Apply Sealers according to the relevant Product Installation Guide

What if I Don’t Have Enough Products Left?

We sell all the products individually, so you only have to buy the items that you need to finish the job.  Please feel free to get in touch if you would like us to help work out quantities.

Can I Use a Sample Pouch for Touch Ups?

You potentially can use a sample patch to complete small touch ups, but please contact us first.  The sample pouches are all supplied in Microne Medium Continuous.  For the colour best match, touch up’s should be completed in the same product that was used initially.

Leave to Dry

Leave for at least 48 hours. Light use only for the first 14 days.  For more information on caring for your microcement surface, visit the guide below:
