A tile gap filling mortar comprises a base material and an additive, and the base material comprises, by weight, 370-420 parts of ordinary Portland cement, 520-580 parts of sand and 40-50 parts of heavy calcium powder; and the additive comprises, by weight, 2-3 parts of high-molecular xanthan gum powder, 0.25-0.75 parts of hydroxypropyl methyl cellulose, 5-10 parts of re-dispersible latex powder, 1-2 parts of a water repellent, 1-3 parts of glass water and 1-5 parts of a water reducer. The increase of the additive improves the water retention and the bonding force of the mortar, reduces the shrinkage of the mortar and increases the ageing resistance of the mortar, so the mortar can effectively fill gaps between tiles, and slit cracking is avoided. The addition of the water glass makes the adhesion stress and the acid and alkali resistance of the mortar enhanced. The addition of the water repellent enhances the corrosion resistance of the gap filling mortar to make a permanent waterproof film formed.
