Polyfilla® wall tile grout is a specially formulated water and stain repellent, ready to use grouting compound for ceramic wall tiles. Recommended for both new ceramic tiling and re-grouting applications. When dry, it forms a hard, long-lasting, waterproof joint between tiles. Polyfilla® wall tile grout is siliconized and does not require a grout sealant. It comes in either a tub for larger grouting jobs and also a squeeze tube that is convenient for smaller repair jobs.
