This specification outlines general guides for the materials selection, preparation, application, and installation for the tiling systems within internal and external covered wet areas (e.g. bathrooms, laundries, balconies).
Ensure substrate is clean, dry, and free from dust, oil, and contaminants. Surface must be structurally sound. Priming is optional depending on condition of the substrate.
Waterproofing - under screed
Use WP MS-PU Polyurethane Sealant as a bond breaker in the corners, FC Sheet joints, structural joints etc. Apply minimum 2 coats of WP-1 PINK waterproofing membrane.
Engineered Screed
Use SCR-100 Engineered Screed to create required falls to the drains.
Ensure that the screed mixture is applied to wet slurry coat as per installation instructions. For slurry coat, mix ADH-55 high polymer tile adhesive to slurry consistency.
Waterproofing - over screed
If waterproofing over screed is required by the relevant standards, guidelines or project specifications, repeat step 2 over screed.
If faster drying time is required, use EP-2 Epoxy Membrane instead of WP-1 PINK.
Tile Installation
ADH-33, ADH-44, ADH-55 or ADH-66 are suitable for wet areas tiling. Check Specification Document or product pages to select the best option for your job.
Grout & Silicone
Choose from a wide range of colours of Spectrum Futura Lightweight Grout suitable for joints from 1mm to 30mm wide.
Select a colour of Spectrum Futura S-25 silicone to match the grout for all movement and perimeter joints.
