Here is a brief comparison of the two materials: Mortar Concrete A mixture of water, cement, and sand A combination of water, cement, sand PLUS gravel, and other aggregates Higher water to cement ratio Lower water-to-cement ratio Thicker consistency Thinner consistency than mortar Used to construct and repair brick, block, and stone structures Used for structural support of a building, steps, sidewalks, and setting postsĪlthough both concrete and mortar contain cement and sand, adding gravel and other aggregates makes concrete stronger than mortar. Typically used as a bonding agent, mortar does not dry to the same strength as concrete, a common building material.ĭue to its strength and durability, concrete is used for support structures and should not be replaced with mortar, as they are not interchangeable. Mortar does not harden like concrete, as it is not as strong.

If you are not using a scratch coat on the concrete, be sure to keep the surface wet. If the concrete surface you are working with is dry, it will draw all the moisture from the mortar mixture you are applying. That is why it’s advisable to apply a scratch coat first for the two surfaces to bond easily.

It will be hard for the mortar to stick to your concrete if it lacks moisture. Actually, concrete must be wet for the mortar to stick to it. You should apply Thinset in small amounts, as it dries very quickly, and you should never wash it down your drain. It’s a mix of cement, water, fine sand, and an agent for water retention, such as an alkyl derivative of cellulose. Thinset, while also sometimes referred to as a “mortar,” is an adhesive and classified as a mortar specialty product. You can also opt for Thinset instead of regular mortar. If the mortar becomes too dry too quickly, it will compromise the bond. You will want to work quickly as the drier the concrete becomes, the more it will draw moisture from the mortar. The scratch coat will help the concrete stay wet so that you can apply the mortar. Wearing a pair of rubber gloves, you can use your hands to apply the watery mixture. Once you’ve mixed up some of this “scratch coat,” apply a thin layer to the concrete you wish to cover. Apply a “Scratch Coat”Ī scratch coat is simply an extra watery, “soupy” mixture of the mortar with which you wish to cover the concrete. There are two ways to get the mortar to stick to concrete effectively: 1. How Do You Get Mortar to Stick to Concrete? It can clean hard-to-reach surfaces and take care of both liquid and solid stains. Aside from saving time, it’s does the best job out of the bunch. Power Washer – Out of these three tools, the power washer is what I recommend.A few rounds of spraying should help you do away with dirt and stain. Hose – To save time, you can also use a hose to spray down the concrete.You can also use it to even out the surface before putting in the scratch coat.

Chisel – If the concrete surface has stubborn stains, a chisel is effective in removing them.To make this happen, here are a few tools you can use: The idea is to not have any other material in between the mortar and the concrete. Removing any old paint, oils, dirt, rust, or stains is crucial to creating a surface that mortar will bond to. The first and most crucial step is making sure that the concrete surface is clean. Mortar mix does not readily bond to old concrete surfaces, and that’s why it’s necessary to prepare the surface beforehand. Mortar will bond to concrete only if follow the proper procedures.
