Waterproofing Newcastle homes is highly recommended so that tiles are protected from damage, particularly in areas where there are plenty of activities and traffic, such as the entranceway, the bathroom and the kitchen. Because water can easily seep through surfaces, tiles can become moistened, or develop moulds or cracks, or worse, warp and deform due to the conditions around it. Using waterproofing coatings can help the quality of the tiles last longer.
But there are many types of coating with different results and advantages. Below are some of the most commonly used types of coats:
1. Concrete waterproof coating
This type of waterproofing is usually applicable in areas that often get wet, like the bathroom and toilet. The process of application is rigid and allows only a little bit flexibility. It’s still best to use for bathrooms, however, because it will help minimise contraction and expansion that can happen in an area where there is not enough sunlight. Additionally, the coating is helpful in reinforcing structures against chemicals that may seep through the tiles.
2. Liquid waterproof coating
This type has a thin coat and is usually applied with a primer, at least two coats, and then a topcoat. Compared to cement or concrete coating, this option is more flexible and seamless. It also offers faster drying time and curing. A few hours after coating, the tiles would be ready to install. The process of application is also quick and simple, with no special mixing or application required. Liquid coats are more solvent and are considered non-flammable so they are the safest to use.
3. Bituminous waterproof coating
This type makes use of bitumen-based components that are so sensitive to sunlight that it can turn tiles brittle should it become exposed too long. Some bitumen coating however, are mixed and modified with other bases like acrylic or polyurethane coats, so that it can adapt to long sunlight exposures. With this type of coating, flexibility depends on the type of polymer that is usually added to the bitumen.
The process for application may be two-fold: self-adhesive membrane or torch on membrane. Self-adhesive types provide fast bonding so that it cuts down the work in half, while torch on membrane bonds better on the surface, and has a longer shelf life.
Bitumen coating largely used to fill expansion joints and cracks, such as in pavements or floor decks, and even rooftops.
4. Polyurethane liquid coating
Meanwhile, this type is ideal for exposed areas because it has the highest flexibility among other types of coats. It’s also more expensive. The process for applying this coat, however, is deemed very sensitive so that application must be done at the best time and during favourable conditions. Moisture is bad for polyurethane that if done badly, the tile may peel or detach in no time.
