Sanded-vs-Unsanded-Caulk What type of caulk to use for backsplash

Sanded caulk is formed of latex, silicone, or acrylic and contains sand for texture and bulk, whereas unsanded caulk does not contain sand. The difference between sanded latex caulk and unsanded caulk is that unsanded caulk is smoother and more suited for tiny tile joints, whilst sanded caulk is better suited for larger tile joints.

Mould is frequently resistant to standard, unsanded caulk. Sanded caulk, on the other hand, is not and can promote the formation of tile mould, which has a foul odour and offers a health concern.

Sanded caulk is less flexible than unsanded tile caulk due to the presence of an impurity (sand), making it more prone to cracks.

Unsanded caulk is also preferred over sanded caulk in locations where water is present on a regular basis, such as bathrooms and kitchens. This is due to the fact that it does not shrink during the curing stage and, as a result, is unlikely to fracture and re-expose the areas between the tile joints.
