Waterproofing methods
Liquid Waterproofing Membrane
Liquid Waterproofing Membrane
Liquid Waterproofing Membrane
Description: A liquid waterproofing membrane is a flexible, rubberized coating applied to the shower area with a brush or roller.
Advantages:
Easy to apply and can conform to complex shapes.
Seamless application, reducing potential points of failure.
Quick drying and ready for tile installation.
Steps:
Clean and prepare the substrate.
Apply a primer if required.
Apply the liquid membrane evenly, ensuring full coverage.
Allow the membrane to cure as per manufacturer instructions before tiling.
Materials:
Liquid membrane (e.g., Red Gard, Hydro Ban).
Brush or roller.
Sheet Membrane Systems

Liquid Waterproofing Membrane
Description: Sheet membranes are pre-formed sheets of waterproof material that are adhered to the shower substrate.
Advantages:
Consistent thickness and durability. Provides a strong, impermeable barrier. Suitable for both walls and floors.
Steps:
Prepare and clean the surface. Apply a thin-set mortar or adhesive. Embed the sheet membrane into the adhesive, smoothing out air bubbles. Seal seams with compatible adhesive or seam tape. Let the adhesive set before tiling.
Materials:
Sheet membrane (e.g., Schluter Kerdi, NobleSeal TS). Thin-set mortar or appropriate adhesive. Seam tape (if required).
Cementitious Waterproofing

Cementitious Waterproofing
Description: Cementitious waterproofing involves using a cement-based waterproof coating. This method is often used for masonry or concrete surfaces.
Advantages: Durable and long-lasting. Easy to apply and readily available. Can be painted or tiled over once cured.
Steps: Clean and dampen the surface to be treated. Mix the cementitious waterproofing compound according to manufacturer instructions. Apply the first coat with a brush or trowel. Allow the first coat to dry, then apply a second coat. Let the coating cure completely before proceeding with tiling.
Materials: Cementitious waterproofing compound. Brush or trowel.
Foam Board Systems
Polyurethane Membranes
Cementitious Waterproofing
Description: Foam board systems use rigid foam panels with a waterproof coating on both sides, which are installed directly onto the shower walls and floor.
Advantages: Provides insulation in addition to waterproofing. Lightweight and easy to cut to size. Fast installation with pre-formed panels. Steps: Prepare the shower cavity. Cut foam boards to size and fit them to the walls and floor. Attach the boards using thin-set mortar or screws and washers. Seal all seams and joints with waterproof tape or sealant. Allow the adhesive and sealant to set before tiling.
Materials: Foam board panels (e.g., Wedi, Kerdi-Board).Thin-set mortar or appropriate adhesive. Waterproof tape or sealant.
Polyurethane Membranes
Polyurethane Membranes
Polyurethane Membranes
Description: Polyurethane membranes are highly flexible, durable waterproof coatings that form a seamless barrier.
Advantages: Extremely flexible and resistant to movement and cracking. High resistance to chemicals and weathering. Suitable for various substrates, including concrete, wood, and metal.
Steps: Clean and prime the substrate. Apply the polyurethane membrane with a brush, roller, or spray. Ensure full coverage and proper thickness. Allow curing as per manufacturer recommendations before tiling.
Materials: Polyurethane waterproofing membrane. Brush, roller, or sprayer.
