Are you looking for a simple, cheap travertine repair kit to fill holes appearing in your beautiful Travertine Floor?
This article will show you how to get an easy to use repair kit for travertine for under £20, that will last you for years to come.
Before we start, it is worth wile understanding why holes appear and more importantly why they will continue to appear.
Why Do Holes Appear In Honed Travertine Tiles
Natural travertine is full of holes , caused by gas bubbled trapped in the stone when it first formed, leaving the stone sponge like, with a honeycomb structure.
If you look at the underside of the tile you will see the natural holes in the stone.
When the stone is processed into floor tiles, the holes on the facing surface of the tile are filled before smoothing and polishing.
That is why the tiles are called filled travertine.
Holes appear in filled travertine tiles for two reasons:
- a hole just below the surface is exposed when the thin layer of stone above it is damaged.
- filler in an existing hole breaks down.
The problem with holes is that they fill with dirt, making your floor look ugly.
There are two ways to fill holes in travertine tiles.
Two-part resin based filler or sanded grout.
We recommend homeowners to use sanded grout for a travertine repair kit. Even if you enjoy diy, we still suggest that you use sanded grout because grout filling is much cheaper, easier to do and gives you excellent results.
Filling Travertine Holes With Sanded Grout
You Will Need
- 5kg bag Mapei Keracolour FF, available here £6.20
- Some water or 1 litre bottle of Mapei Fugolastic available here for £4.60. The Fugolastic makes the grout harder and more improves its water resistance.
- A few disposable party cups or bowls and plastic spoons etc for around £1.50
- A few pairs of disposable vinyl or plastic gloves, £1.50
- A dry microfiber cloth £1.00
- The bowls, spoons, gloves and cloth are all available from Wickes or your local supermarket; Azda, Testo, Sainsburys etc.
I suggest you keep all the items ready in a box ready for use.
Most hole repairs will need one to three teaspoons of grout, so the grout will last you a long time.
How to mix the grout
Mix one or two teaspoons of grout with the recommended amount of water or fugolistic additive With small quantities like this, I use a pair of electronic kitchen scales, because you will be working in grams of water or additive.
Thoroughly mix the grout and then leave it undisturbed for around five minutes. This is a critical step to allow the grout to slake.
Slaking is an industry term for allowing the liquid to completely penetrate the grout.
The grout will usually stiffen during the slake time and appear unworkable and difficult to spread. To return the grout to a workable consistency, all you need to do is remix the grout without adding any more liquid. The action of the mixing will return the grout to a workable consistency
If you want to understand more about slaking watch this video.
Put some grout into the holes and smooth them off with the back of the spoon or your gloved fingers.
If the hole is large, you can use a decorating knife
Don’t spend much time trying to smooth the grout, that will come later.
Leave the grout until you see the grout residue around the repair start to dry and opaque.
Use the dry microfiber cloth and gently rub the cloth over the repair to remove the excess grout and opaque grout haze off the tile. This process will smooth the grout.
Use a vacuum cleaner nozzzle to vacuum up the grout dust.
Leave the grout to go hard overnight.
Filling Travertine Holes With Two Part Resin Fillers
If you search online for a travertine repair kit you will see plenty excellent resin-based filler alternatives such as:
We use all of these fillers, and they do an excellent job of filling holes, however they are best used by professional restorers because they are not simple to use.
- the resins in them have a strong smell that you may find unpleasant.
- if you get these resins on your skin, you need acetone to remove them, which will irritate your skin
- the resins will start to set after around 5 minutes, so if you have a lot of holes to fill, you will need to mix a number of batches.
- there will be a small amount of resin above the repair that needs to be smoothed flat with the surface of the tile. There are two options for smoothing resin.
Grinding Travertine Filler
Grinding the filler smooth is done with a slow speed grinding machine and special carbide pads. The machines cost over £200.00 (Our machines cost over £400.00) and the disks cost at least £50.00 per pack. You also need a vacuum to remove the dust. Also, you need to take care not to damage the surrounding surface of the stone.
Scraping Travertine Filler
Small repairs, under 10mm diameter, can be scraped using a sharp blade. Again this is not as easy as the instructions lead you to believe. First you need to kneel or lie down on the floor while you work. Next you need to scrape backwards and forward over the filler, gradually shaving off small amounts until the filler is smooth with the stone. Filler is a hard material and this can easily take 30 mins to achieve. Finally, it is extremely difficult not to scratch the surrounding tile, especially when your fingers are tired.
If you are an enthusiastic diy’er, then these issues should be of little concern to you. But is you are not keen on diy, then we recommend you use a sanded grout.
