Starx 345: Premium Polymer Based Tile Adhesive for Floors & Walls

A Time-Saving, High-Bond Formula for Interior, Exterior & Underwater Use

Last updated: 22 September 2026

Starx 345 Polymer Based Tile Adhesive is a premixed, polymer-enriched blend of cement, silica and special polymers used to fix ceramic tiles, vitrified tiles, stones, pavers and bricks on floors, walls, facades and underwater surfaces. It delivers high bond strength, zero wastage and no shrinkage, staying flexible enough to absorb minor structural movement while resisting extreme weather. One 20kg bag — available in Grey and White — covers approximately 55–60 sq ft when applied with a 1/4" × 1/4" (6mm × 6mm) square-notch trowel at a 3mm bed thickness, with a pot life of up to 45 minutes and a setting time of 24 hours at 30°C ambient. Mixed with water, it offers a long open time and excellent workability, requiring only ordinary labor and standard tools to apply — no additional additives or specialized training needed.

Advantage

This adhesive can be used directly on walls, underwater, and on a wide range of surfaces. It is a single component product — simply mix with water to get maximum bond strength, with no extra additives required. Just make sure the surface is free of loose particles before applying, for the best adhesion.

Application

Suitable for both interior and exterior facades as well as underwater applications. It works well for laying ceramic tiles, vitrified tiles, stones, quarry tiles, pavers and bricks. Before applying it, make sure the surface is clean, free of loose particles, and strong enough to hold the tile.

Suitable Surfaces

This product works on: Concrete, Cement Plaster, Cement Tiles & Stones, Brick Masonry, Exterior Grade Plywood, Gypsum Wall Board, and Ceramic Tile & Stone.

Coverage

One bag covers approximately 55–60 sq ft per 20 kg when applied with a 1/4" × 1/4" (6mm × 6mm) square-notch trowel for a 3mm bed — meaning excellent economy and virtually zero wastage with this formula.
