The majority of balconies have a concrete construction, and although you may find tiles, marble, or even wood placed over the top, the original structure of balconies that are not made of materials such as wrought iron is concrete. Concrete is tough and you would think that it would be fairly indestructible. However, you would be wrong. Concrete is actually porous, and this means that in order to have a long lasting balcony, you need to think about balcony sealing that will stop the rock like substance from absorbing water.
You may not give a second thought to the concrete of your terrace or balcony, until you suffer from high rainfall or snow and ice. It is easy to see just how absorbent concrete is unless it has been treated correctly. Try spilling a little coffee or red wine on your concrete floor and you will see how it does not just sit on the surface but soaks in and creates a stain.
What this means is that if you fail to use the correct balcony sealing techniques for your concrete terrace, over time the structure will weaken and you will see cracks appearing as the slab actually expand as it fills with water. If temperatures drop and your balcony freezes with water inside, it will expand, crack, and once it dries out it can be extremely unsafe altogether.
Balcony sealing for concrete balconies stops moisture getting into the slab or cement, an impregnating sealer stopping water getting in. The process is quick and simple, and offered by your local Bristol balcony experts for a very reasonable price. The results are fantastic. Not only will your balcony be safe and water resistant. It will also be stain-proof and easier to clean.
There are various different sealants using in balcony sealing, and these include both water based and silicone sealants. Silicone based sealants are a more expensive option than water-based sealants, but they last longer and will need to be applied less frequently. As silicone is not affected by water at all you can seal your balcony with a silicone-based sealer the day before a huge storm and the process will not be affected in the slightest. One downside to silicone sealers that should be noted however is their strong levels of VOCs, which give them an unpleasant odour that may hang around for some time.
Water based sealants are easier to apply if you are thinking of carrying out the task yourself, but the sealant can be easily washed away by water. For this reason, if you live in a harsh climate such as the UK, silicone sealing treatments available from your Bristol balcony experts are the better option all round. It is also crucial that you pick a time of year when you will be guaranteed a few days of good weather for sealing your balcony.
The preparation for sealing your balcony can be carried out by your professional balcony cleaning team, the dirt and grime being scrubbed away to provide a surface that is perfect for sealing. If you are attempting the job yourself, start by applying the sealant to the edges and around the banisters, then carrying on applying an even coat of seal to the main area of your balcony or terrace. Your balcony should be resealed once a year for optimum results, and this is once again something you can discuss with your balcony experts in Bristol.
