- Basements, bathrooms, and kitchens must maintain waterproof conditions at all times in order to prevent a variety of problems. It is quite common for homeowners to suffer from mould growth, water damage, or both, but you can prevent these problems with the right materials or more specifically "sealants".Sealants are widely used by construction professionals as well as homeowners as a way to seal cracks on surfaces and prevent further damage. However, if water damage is the primary concern, it is usually best to use a waterproof sealant.Here is a list of the more common sealants and their applications.
    
    ### Silicone Sealant
    
    Silicone sealants continue to be one of the most popular sealants on the market. Its power, flexibility and durability make it ideal for a wide range of applications.It appears to be a flexible but tough rubber, commonly found on bathtubs, faucets, vents, roofs, and even windows.Your home's gaps and seams can be glued together using silicone sealants. Sealants are often used in automotive applications since they can withstand high temperatures. Local hardware stores usually sell them as caulk guns, which come in a variety of variations.While there are other sealants with greater strength, silicone sealants are known for their flexibility and durability, the two characteristics that make them such popular sealants.
    
    ### Waterproof Sealant
    
    Waterproof sealants are a great way to protect materials and surfaces from water damage. They can also be used to prevent sun damage and temperature fluctuations caused by ultraviolet radiation.
    
    ### Gasket Sealant
    
    Essentially, a gasket sealant consists of a solution (usually in the form of a spray, paste, or glue) that is applied to the gasket to hold it into place. Reducing friction between parts, prevents fluid leakage and mechanical breakdowns.In both vehicles and industrial machines, gaskets play a major role in engines. It is common to use sealants to reinforce and keep joints reliable, despite their reliability usually being fairly good on their own.
    
    ### Polyurethane Sealant
    
    Polyurethane sealant is easy to paint over, which is beneficial for concealing waterproof sealants under decorative features.Due to its durability and non-shrink ability, both flooring and car interiors can use it. These sealants, however, have the disadvantage of lasting less when compared to silicone sealants, as well as being less resistant to extreme temperatures and ultraviolet light.**What's the difference between sealant types?**Silicone sealants - among the most widely available sealant types, and ideal for a wide array of household, DIY and construction tasks.**Why are sealant modulus and cure type important?**High modulus sealants are less elastic but more hardwearing, and better suited to indoor applications as a kitchen or bathroom sealant (around baths, showers, sinks and worktops).Low modulus sealants offer better flexibility and adhesion where slight movement of the joint may be a factor, but are less hardwearing overall. They're generally best for outdoor and weather-resistant applications (perimeter seals and exterior UPVC).Most sealants are available in one of two cure types - acetoxy and neutral.High modulus sealants tend to be acetoxy cures, meaning they'll cure faster and harder, and will emit a slight vinegar smell while doing so.Low modulus sealants are often sold in natural cure variants, meaning they adhere better to a greater range of surfaces, cure slowly to a more elastic consistency, and give off little odour.


Waterproofing sealants include polyurethane sealants and silicone sealants. Waterproofing surfaces can also be done using silicone glue. Get them from RS online.

<p>Silicone sealants are adhesives that are most often used to create a water or airtight seal in the joint between two surfaces. Silicone sealant has a gel consistency which cures by drying over a period of time, with the correct temperature and humidity. The cured product is a durable yet flexible, silicone rubber. </p><h2>Why use a silicone sealant?</h2><p>They are very easy to use and enable you to create a waterproof join with minimal effort. The sealants are weatherproof and can withstand a wide range of temperatures. The sealants bond to many different materials, are long-lasting and do not promote mould growth. </p><h2>Types of Silicone Sealants:</h2><p>Silicone sealants come in a range of different colours such as black, grey, white and clear. They typically come in a cartridge or tube and many have a nozzle for precise bead application. There are squeeze tubes which are used by hand or rigid tubes for use with a sealant gun. Silicone sealants use different chemicals such as acetoxy, alkoxy and elastomer. It is essential that you choose the relevant chemical base for your application. Most silicone sealant is multi-purpose and can be used for general applications and bonds with many materials. Sanitary silicone sealants are best for wet applications for example in bathrooms. This is because they are resistant against mould and mildew. </p><p>Other things to consider when purchasing a silicone sealant is whether it is suitable for indoor or outdoor use, is it mould resistant, or whether you have any specific operating temperatures that could affect the efficiency of the silicone. Both heat and cold can affect silicone sealant and compromise its ability to seal.</p><h2>What are they used for?</h2><p>Silicone sealants are commonly used in both domestic and commercial environments. They are an essential DIY material for use as a bathroom sealant or in window construction. Other applications include:</p> <ul><li>Shower sealing</li><li>Window glazing and doors </li><li>Cooker and fridge sealing </li><li>Plumbing joints</li><li>Electrical repair</li><li>Wire entry seal</li><li>Junction protection</li></ul>

<p>Adhesive sealants, also known as hybrid sealants or combined sealants, offer an innovative solution to sealing, with the flexibility and elasticity of a sealant and the high strength and durability of an adhesive. This makes them a perfect adhesive for gap filling and general-purpose adhesion between two surfaces. The sealants and adhesives once dried can be painted over and are weatherproof, making them ideal for a variety of bonding and sealing applications.</p> <h2>What are the benefits of adhesive sealants? </h2> <p>Combined adhesives and sealants are versatile as they combine silicone and polyurethane sealant to create a multipurpose sealant that can bond with a range of materials, such as concrete, wood, metal and plastic. In general, adhesive sealants benefit from low odour, a large temperature range and good movement capability. They offer a good initial grab rate, which gives them more flexibility, whilst also being very resilient. The adhesives are UV stable, and do not yellow or degrade.</p> <h2>Applications and Uses</h2> <p>The new adhesive technologies of a hybrid adhesive can bond with a wide range of substances and materials, making them useful in both interior and exterior applications. They come in a variety of colours, sometime clear, and can also be painted over. Relevant applications may include glazing and windows, flooring, and as a gap filler. </p>
