Thinset mortar is a type of concrete composed of Portland cement, fine silica sand and water that is typically used to set interior tiles. The most common application is for bathroom tiling jobs. Though the concrete is applied in thin layers, it is surprisingly strong. Properly mix together the thinset mortar for your project to ensure that it is accomplished in a professional-looking manner.
Pour cold tap water and the thinset mortar mix into the bucket in accordance with the ratio described on the packaging instructions.
Thoroughly stir the mixture with a hand trowel until the mortar and water are fully integrated. The texture should mimic that of peanut butter. If the mixture is too thick, add a small amount of cold tap water and stir it in until it achieves the proper consistency.
Allow the thinset mortar to settle in the bucket for approximately 20 minutes, then stir once with the hand trowel and apply it as desired to complete your project.
