What is cementitious waterproofing ?
Cementitious waterproofing refers to cement-based waterproofing. It is recommended that surfaces be free from dirt or foreign materials. For the waterproofing to work best, manufacturers recommend the surfaces be sand blasted, bush-hammered or acid-etched. This will insure maximum contact with the surfaces and 100% waterproof.
Cementitious waterproofing is applied in two coats. The first coat could include the manufacturer’s materials only. The second coating will include a cement-sand mixture and also have chemical and metallic elements too. If supplementary waterproofing is required, then a third coat may be required. This typically includes sand and cement for that extra protection.
There are three methods of applying this type of water proofing.
- Trowel -This technique derives its name from the tool used, a trowel. Application of the coating is done using the handheld trowel, by simply applying and spreading the coating using the trowel.
- Spraying - This method uses spraying equipment much like the ones used in painting industrial vehicles. It is preferred due to its precise finish and efficiency. It is also faster to use the spraying technique rather than the trowel method.
- Brush - This technique uses a typical brush similar to roll brushes that are used in painting houses. It also has a uniform finish and is faster to use compared to the trowel.
It is good to note that different surfaces will dictate the method of application. All of the methods are effective in delivering a superb cementitious waterproofing.
