Roff T07 Extrofix Grey Tile Adhesive | High-Flexibility S1 Polymer-Modified Bedding for Exterior Walls & Facades (30 Kg Bag)

Provide a permanent, shock-absorbing anchor for demanding outdoor surfaces with the Roff T07 Extrofix Grey Tile Adhesive. Expertly engineered by Pidilite for high-exposure environments, this ultra-premium, highly polymer-modified cementitious compound is designed to withstand structural stress, vibrations, and severe weather fluctuations.

Exterior walls, high-rise building facades, open terraces, and balconies undergo constant movement due to heavy wind pressures, seasonal temperature shifts, and structural settling. Traditional rigid mortars fail under this stress, causing tiles to crack or fall off. This heavy-duty 30 Kg commercial pack solves outdoor engineering vulnerabilities completely by utilizing a highly deformable S1-class flexibility framework that absorbs structural shifting while maintaining an intense, unyielding grip.

Key Features & Benefits

• Class S1 High-Deformability Matrix: Formulated to bend and flex slightly without breaking, safely absorbing heavy building vibrations, wind loads, and thermal expanding stresses.

• Engineered for Exterior Facades: Delivers maximum industrial strength, making it the premier choice for installing heavy vitrified tiles, large porcelain slabs, and thick natural stones on high vertical outdoor walls.

• Extreme Weather & Water Resistance: Specially modified to repel monsoon rains, intense summer heat, and frost cycles, preventing water ingress from degrading the underlying structural bed.

• Advanced Anti-Slip & Non-Sag Formula: Features an improved initial grab structure that instantly grabs heavy tile backings, stopping vertical sliding or sagging during wall placement.

• Prolonged Open Time Utility: Offers a generous 30-minute open working window, allowing structural masonry crews ample time to shift, align, and perfect spacer joints on complex outdoor layouts.

• Fully Conforms to IS 15477 Type III: Certified to meet strict IS 15477:2019 (Type III T) and international ISO 13007 C2TES1 criteria, ensuring maximum safety clearance for architectural high-rise facades.

Mixing & Application Guidelines

• Water Ratio Mix: Gradually add roughly 1 part water to 3.8 parts powder by weight into a clean mixing container. Blend thoroughly using a slow-speed mechanical stirrer until a uniform, lump-free paste forms.

• Slaking Phase: Let the wet mix stand and react for 5 minutes, then stir briefly for 60 seconds. Do not add extra water after this step has passed.

• Application Method: Spread the adhesive layer onto the concrete or plastered surface using a professional notched trowel to guarantee complete bed coverage. For exterior vertical applications, back-buttering the tile backing is highly recommended.
