Damp stains on a room wall are a more common problem than we think, and can arise for a number of reasons: leaks, lack of insulation, or poor ventilation or condensation among others. Fortunately, there are ways to treat these dampnesses without getting too complicated.. In this article we will show you how to identify, prevent and solve them. In addition, we will explore the Tecpint Termic from Tecno Prodista versatile product that offers an effective solution against humiditykeeping the walls of your home dry and protected.
Why does dampness appear on the walls of the room?
Before applying any solution, it is essential to understand where the damp is coming from, as this will determine the appropriate treatment. Here are some of the most common reasons:
- External leakageIf your wall is directly exposed to the outside, leaks from rain or pipes can cause damp problems. If you suspect that you have a leak from the outside, you will have to pre-treat the problem on the outside with Tecno Prodist products from the range waterproofing
- CondensationCondensation occurs when moist indoor air meets a cold surface, creating small water droplets that accumulate.
- Lack of ventilationA poorly ventilated room favours the appearance of damp, especially in winter, as the air does not circulate and the excess humidity in the room is trapped.
Once you have identified the source, you can begin to work on an effective solution, and this is where the Tecno Prodist products play a key roleproviding a protective layer against moisture.
Step by step: How to remove damp from a room wall
1. Preparation of the affected surface
Before applying any damp-proofing product, it is important to prepare the wall for long-lasting results. Here are the basic preparation steps:
- Deep cleaning: Remove the damaged paint or coating, clean the mould stains with water mixed with bleach, the easiest way is to mix 1 part bleach to 4 or 5 parts water in a spray bottle and spray the area with mould stains, leave to dry, if necessary repeat the operation or reduce the proportion of water (use gloves, mask and goggles when applying) and make sure the wall is completely dry before applying the subsequent paint.
- Crack repairIf dampness has caused cracks in the wall, seal these cracks with TECPINT PUTTY before the application of the paints
2. Application of damp-proofing treatment
This is where specialised products come into play, such as Tecpint Termic from Tecno Prodista damp-proof paint that fights dampness and also offers thermal and acoustic properties.
- First layer of protectionApply an even coat of Tecpint Termic by brush or roller diluted with 10% of water. This product adheres easily and creates a barrier that blocks moisture and condensation.
- Adequate dryingAllow the first coat to dry for 6 - 8 hours to ensure its effectiveness. As it is a water-based paint, the drying process is usually fast and without unpleasant odours.
- Application of additional layersApply two more coats (3 in total) neat or thinned with a maximum of 5% of water, always allow 6-8 hours drying time between coats. This will increase the durability and resistance of Tecpint Termic, damp-proofing and thermal insulation
- Reinforcement and complementary treatmentIf you notice that you have a problem of thermal break (walls facing the outside or very cold pillars in winter) to achieve a complete treatment and greater thermal effectiveness, you can apply on those walls or colder areas a layer of 0.5 cm of TERMOMUR FLEX before applying TECPINT TERMIC
How to keep a room free of moisture
Once you have solved the initial problem, it is important to carry out regular maintenance so that moisture does not reappear.. The Tecpint Termic from Tecno Prodist can also be applied preventively to walls that have no visible damage, protecting them in the long term and contributing to a drier, healthier environment in your home.
Practical tips to prevent moisture in the future
In addition to treating the wall with Tecpint TermicThere are other measures that you can implement to prevent the appearance of new dampness.
- Regular ventilationOpen the windows and doors of the room so that air can circulate and humidity does not accumulate.
- DehumidifiersThese devices are very effective in reducing the humidity in the air, especially in rainy climates or seasons.
- Wall insulationIf the wall is exposed to the outside, improving the thermal insulation is a good idea to avoid condensation, you can apply a layer of 0.5 cm of TERMOMUR FLEX
Frequently asked questions on how to remove damp from walls
Dampness in the walls of the room does not have to be a permanent problem. With the help of Tecpint Termic from Tecno ProdistIf you have a damp-free home, you can not only eliminate it, but also prevent its reappearance, thus achieving a healthier and more humidity-free environment in your home.
Can I apply Tecpint Termic directly on a mouldy wall?
No, before applying Tecpint TermicIf the wall has been cleaned thoroughly, it is essential to thoroughly clean the wall and remove the mould with water and bleach, as we have explained. This ensures that the damp-proofing treatment is effective and long-lasting.
How many coats of Tecpint Termic should I apply?
For walls with slight moisture problems, two coats are usually sufficient. However, if the dampness is persistent, a third coat is recommended to ensure complete and long-lasting protection, also if you want to achieve a thermal effect on the product.
Is it necessary to apply Tecpint Termic periodically?
Frequent application is not necessary, but maintenance every 3 - 4 years can help to keep the damp-proofing in perfect condition, especially in rooms with a lot of exposure to moisture.
