There are many steps to laying a concrete overlay. The following article will walk you through the prep period to the cleaning up period. It is important to remember to have the correct materials including Portland cement, fine and coarse sand and pea gravel. Work in sections and be sure to spray the surface with a curing compound (or cover with plastic) when its finished.

The most common problem with concrete drives, sidewalks and patios is surface spalling. The upper wear surface simply flakes off. The attractive surface is now replaced with bumpy aggregate. This can be repaired by adding a concrete overlay. Adhesion is the key to installing a new concrete overlay, as well as the thickness you choose to apply.

The following publications are excellent source materials for facts about how concrete should be mixed, placed, finished and cured. All of these things must be done properly to ensure that your concrete will be durable and long lasting. While the ingredients in concrete are common - sand, gravel and water - many people don't realize that cement is crucial for making durable concrete.

Installing concrete to achieve long lasting, high quality results depends on many things. Some of the most important aspects are often overlooked, like its strength, application thickness, its cracks that form from shrinkage and the use of steel reinforcements. Understanding these components will lead to better results.

Concrete sealants are sold at many places. You can generally find them at building supply stores, hardware stores, etc. Shop around and read the product labels completely to see if the product will suit your needs.

Concrete is a very magnificent material. As you know, you can form it into almost any shape, you can apply many different finishes to it, you can stamp it with patterns, etc. Concrete has its strengths and weaknesses. You must minimize its weaknesses in order to maximize its useful life. There are several inexpensive yet effective ways to do this.

Concrete sealants are products designed to inhibit and/or prohibit liquids from being absorbed by concrete. Concrete, contrary to popular belief, is actually a porous material. It can and does absorb water and other liquids. Some of these liquids can have dissolved materials (salts, acids, etc.) which can severely harm the concrete. Water can enter concrete and freeze. Water which freezes expands by approximately nine percent. This expansion can literally tear concrete apart. It is a good idea to apply a concrete sealant to avoid such problems.
