Renovate balcony and tiles

Special attention should be paid to a balcony as it is exposed to the weather all year round. In order to avoid a complete renovation, the balcony and tiles can also be professionally renovated in various stages and protected over the long term. Below you will find comprehensive tips and information on the various renovation options.

The effects of the weather on a balcony should not be underestimated

A balcony is literally at the mercy of the weather all year round. In summer the sun hits the balcony and the structure expands massively. Rainwater penetrates cracks, where dirt also collects. The wet biotope is advancing, because it doesn’t take long until the first mosses and algae can be seen and the moisture is even better stored. Since balconies are also completely free-standing extensions, they cool down very quickly in winter. During the menopause, the sun warms the balcony during the day, while it is very cold at night - the materials with different properties also move independently of one another to different degrees and work practically permanently against one another.

Damage spreads exponentially on a balcony

Water can now run even better into cracks, slits and breaks. If it then freezes at night, the freezing water blows up concrete, tiles, intermediate layers, etc. From now on, the decline is even faster and more extensive. At the end there is a total renovation. To avoid this, you can intervene in all stages of weather-related decay. Even a single, blown tile drives the destruction even faster and should therefore be repaired immediately. Partial renovation of the balcony tiles is urgently recommended at this stage of the renovation. To do this, remove broken tiles and replace with new ones. On this occasion, however, you should also check all other tiles.

Always refurbish tiles on the balcony with particular care

You can tap off the balcony tiles with a rubber mallet, for example. Remove and replace hollow-sounding tiles. It is also important to thoroughly check the grouting. If the grout shows signs of damage, it is also advisable to completely remove the grout (€ 6.99 at Amazon *) and then to re-grout the balcony tiles. Of course, you also have to carefully check the expansion joints filled with silicone and, if necessary, re-grout them as well. If the moisture has already penetrated the building properly, you should remove the balcony tiles. Before re-tiling, let the balcony surface, which has been chipped off from tiles and adhesives and possibly sanded with a concrete grinder, dry out completely. This can take several weeks or even months.

Use only the best building materials and materials - from glue to tile

Then apply a high-quality barrier layer, don't forget the edges and corners. There are special adhesive tapes here. You may also have to apply a primer to the barrier layer (€ 19.50 at Amazon *). Now you can also re-lay the tiles on the balcony. Also use a highly flexible, plastic-coated tile adhesive for the adhesive. You should choose tiles that can absorb as little water as possible. Then joint the joints with a flexible joint mortar for outdoor use, and finally the expansion joints with silicone.

Renovate balcony tiles: touch up or re-install tiles on tiles

If the moisture has not yet penetrated the balcony structure, in addition to repairing individual tiles and the grout, laying tiles on the old tiles is an alternative option as a means of renovating the balcony. Remember, however, that the masonry or. the concrete of the balcony has to be really dry. Here, too, apply a high-quality barrier layer to the old tiles before implementing the renovation measures.

Tips & Tricks Old balconies often have no or only an insufficient gradient. Check the slope of your balcony before laying the new tiles and create a sufficient slope if necessary. Also check existing water drainage pipes to see if the water is actually draining. Likewise, puddles must never form on the tiles.

Tiles that are particularly suitable are, for example, porcelain stoneware tiles that are not polished but glazed. However, pay attention to the slip resistance, especially with glazed tiles. The water absorption is less than 0.5 percent. Earthenware tiles can absorb significantly more than 10 percent water and are therefore not frost-proof. Even stoneware tiles absorb up to three percent, so they are only suitable to a limited extent - even if they are declared frost-proof. So porcelain stoneware is best. With natural stone tiles, it depends on the natural stone. In addition, the rougher, the more difficult it is to clean natural stones.

You can protect balconies that are still tight or that have already been newly tiled for renovation reasons. The specialist trade offers appropriate impregnations. They are recommended for polished and glazed porcelain stoneware tiles as well as for conventional glazed and unglazed tiles. Regular impregnation should even be a requirement for non-glazed tiles. With glazed tiles, impregnation is worthwhile because it also protects the joints over the long term.

Damage to the balcony usually begins with very minor incidents. Even the moss in crevices can be dangerous because a lot of water is stored here. which literally blows up cracks in winter. The damage then spreads more and more from year to year. Even if you don't use your balcony: with cellar tiles you can say that you wait until more tiles are broken before you re-tiling. However, you should renovate balconies at the slightest sign of damage. The smaller the damage, the cheaper the renovation. This is offset by an extremely complex and costly total renovation. Above all, do not underestimate the speed at which small damage can grow into large damage.
