WATER REPELLENTS FOR CONCRETE MASONRY WALLS
Water repellents are used on exterior walls to provide resistance to wind-driven rain. In addition, water repellents can also reduce the potential for efflorescence and staining from environmental pollutants, and enhance the color or texture of a wall. These are also called Concrete Sealants - Concrete sealers and sealants are applied to concrete to act as a protective layer while safeguarding the material below. Despite its inherent strength and durability, concrete is a porous material with an absorptive surface, making it susceptible to the intrusion of water, chlorides, oils, and other chemical substances.
TYPES OF WATER REPELLENTS
There are two general types of water repellents:
Surface treatment repellents - Surface treatment repellents are applied to the weather-exposed side of the wall after the wall is constructed. In addition to water repellency, surface treatment repellents also improve the stain resistance of the wall, by preventing dirt and soot from penetrating the surface, causing deep stains. In general, surface treatment repellents should allow for vapor transmission to ensure that interior humidity within the wall and structure can escape. Surface treatment repellents will require reapplication after years to ensure continuous water repellency.
Integral water repellents - Integral water repellents are added to the masonry materials before the wall is constructed.
The water repellent admixture is incorporated into the concrete mix at the block plant. For mortar, the water repellent is added to the mix on the Jobsite.
SURFACE TREATMENT REPELLENTS
Cementitious coatings, Paints, Cement-Based Paints, Clear Surface Treatment Repellents, etc.
Clear Surface Treatment Repellents :
Clear surface treatment repellents are used to add water resistance to a wall without altering its appearance. These are of two types -
Penetrant repellents are also called Penetrating Sealants. Penetrating repellents are absorbed into the face of the masonry, lining the pores. They adhere by forming a chemical bond with the masonry. They penetrate and react chemically within the capillaries of the concrete to shield against moisture penetration and deicing chemicals. It provides excellent protection against outdoor exposure conditions since they provide excellent protection against harsh exposure conditions. It provides invisible protection without changing the surface appearance or leaving a sheen.
Silicones, Silicone resin, silanes, and siloxanes all are penetrating water repellents. They are based on NANOTECHNOLOGY. They will never yellow, fade, or peel. They have a lifespan of 5+ years.
Penetrating Repellents can be HYDROPHOBIC – Which repels water & OLEOPHOBIC – Which repels Oil.
Film Forming Sealants -
Film Forming Sealants are also called Topical sealants. It uses resin such as acrylics, forming a continuous surface over the masonry, bridging very small cracks and voids. Because of this, films can also reduce the vapor transmission of a concrete masonry wall. Films tend to add a glossier finish to the wall surface, and may intensify the substrate color. They generally require higher application standards and maintenance. They form a thin protective film on the concrete surface.
INTEGRAL WATER REPELLENTS
Integral water repellents are usually polymeric products incorporated into masonry products before construction. Because integral water repellents are evenly distributed throughout the wall, they do not change the finished appearance. In addition, integral water repellents are effective at reducing efflorescence, since water migration throughout the block is reduced.
'SEALANT' is “any material placed in a joint opening generally to weatherproof a building, so designed to prevent the passage of moisture, air, dust, and heat through all joints and seams in the structure.” Sealant is a substance that is used to block the passage of fluids through the surface or joints or openings in materials, a type of mechanical seal. They seal the top structures of the substrates and are particularly effective in waterproofing processes by keeping moisture out (or in)
When exterior walls get exposed to rainwater or high humidity, water and moisture can travel through and affect your internal walls. This means that your walls may stay damp for a long time before drying. So, your wall becomes a breeding ground for mold and mildew growth causing irreparable damage and water leakage.
When applied following the manufacturer’s recommendations, water repellents effectively control water penetration. Water repellents are generally recommended for use on single wythe concrete masonry walls exposed to the weather. The choice of water repellent will depend on the surface to be protected, the exposure conditions, and aesthetics.
Sealants & Repellents are important to be used at the right time to prevent water dampness & water leakage. Their use in time -
Protects Interiors From Water Damage
Prevents Onset of Health Problems
Promotes Long-Term Comfort
Protects the aesthetics of the building
Panache having its expertise in Energy Saving & protective building enveloping provides both Surface treatment types, Clear penetrating water repellents, and Acrylic sealants. Panache transparent penetrating clear water repellent grade helps to protect the walls from water dampness due to rains and protects the wall aesthetics for a longer time. The Clear penetrating water repellent works on Nanotechnology to have greater efficiency for water repellency. Due to the Nanotechnology base, the efficiency of the product is far much enhanced and accepted with result-oriented history.
The other film-forming sealant grade of water repellent from Panache helps to give complete sealing & water-repelling properties along with oil & pollution protection too. The film-forming sealant typer water repellents are also added to the enhanced waterproofing portfolio of Panache to give versatile applications as per clients' requirements.
All the products of panache are Green Pro & GRIHA certified. The Company is also in process of getting EPD certification. The use of Panache wood coating products in any project results in Health Benefits, reduction in maintenance cost due to long life & enhancement of the aesthetics. Panache believes in providing. It does not sell only products. The Client's ease & money wood coatings by Panache contribute to reducing the recurring maintenance cost.
The low VOC & water-based systems help to reduce the CO2 & GHG emissions. The Life cycle cost of the wood treatment and items is also reduced. The customized finishes provided by Panache add a lot of value and satisfaction to the clients.
While going for IGBC, GRIHA, and LEED certification of buildings Panache products contribute almost more than 2 to 3 points for Low VOC, No smell, No heavy metals, Innovative design of systems, Local material use, Green Pro, GRIHA certified material.
A Cool Roof coatings consists of a binder (usually an organic compound or silicone compound) blended with pigments and other additives to provide two main benefits: protection of roof membranes for longer roof life cycles; and reflectivity of solar radiation, for lower air conditioning costs.
The main components of most Cool Roof coatings are the binder, pigment, water and reflective pigments. Water serves as a liquid carrier, which provides viscosity, allowing the pigment and binder to be spread on the roof as a thin coating. The majority of white coatings in use today are water-based coatings
An energy efficient , white, reflective, elastomeric coating manufactured by Panache can reflect up to 92% of visible light, keeping the roof surface much cooler than with aluminum, black, or non-reflective roofing materials. Lower temperatures mean less energy usage, and translate to money saved. Elastomeric roof coatings protect the roof substrate adding years to your roof, plus saves against costly tear-offs and re-roofing.
