Unsanded Vs Sanded Grout

Grout for tile joints in home improvement projects.

Introduction

Choosing the right grout affects both appearance and durability of tiled surfaces.

  • Joint width determines whether sanded or unsanded formulas perform best.
  • Moisture resistance and shrinkage rates vary between the two types.
  • Texture and ease of application change depending on sand content.

Compare both options to match your tile layout.

FAQs
