Concrete is vulnerable to a lot of environmental factors due to it’s porous nature. And as with porous surfaces, molds, stains, moisture, along with other environmental hazards can seep in, wrecking havoc on your concrete surfaces.
Water can enter concrete from the top side or in the ground: in two ways. Water entering from the top is called positive wetness. Soil moisture is called negative moisture. It comes from your natural moisture of the substrate over which the concrete is set. Concrete surfaces behave like sponges when exposed to water drawing up the water until it’s saturated. If there’s no further water available then until it reaches equilibrium state.
What does water do to concrete?
Many processes that may lead to noticeable damage are caused by water. The rebar which is embedded in the concrete to give it strength will begin to rust. The concrete is then weakens and may begin to flake away as the corroding steel expands. Water also activates salts and as water seeps into the concrete the alkali salts reacts with the concrete around it.
Water additionally causes mildew, mould and algae to grow. Mold has been recognized to influence health conditions. Algae cause the concrete to become slick while mildew frequently give off a bad odor and causes stains and discolored.
Up to 60% of houses have basements that suffer from this sort of damage. This may critically impact the resale value of your home and also make your home a health hazard to its residents.
Protecting Concrete from Dampness
You need to use a sealer to safeguard your concrete walls or floors. Sealers protect concrete from deterioration caused moulds, stains, oil, damp and by alkaline salts. Additionally, it provides a layer of protection that allows for easier sweeping and cleaning. And can seal minute cracks before they become big cracks and protects concrete joints from debris and moisture that will push apart the slabs over time.
You’ll most likely need just one application of sealant to keep your surfaces protected.
To start with, you should assemble the equipment that is needed. As you are going to work with possible irritants first of all, protective garments must be worn by you. Assemble a water bucket and a brush. Additionally, you will need some rubber gloves, safety glasses and small-particle filter to guard you against chemical brokers. Additionally you will need a paint roller and some paintbrushes. Ensure there’s proper ventilation in the place you are to work together with the sealer.
Follow the following steps:
1. Your area should be free of dirt, grime, grease, and oil. The scrub brush will help remove stubborn stains. Utilize an industrial cleaner to simply help remove the filth. Stubborn spots might need some before they may be removed, soak in a detergent answer. Rinse thoroughly with clear water. A second application could possibly be needed.
2. Remember you had just dealt with a potentially hazardous substance. As you work on your place, always keep safety at heart. Also, get rid of the brushes you employed for the job and the roller. Concrete sealers might require which you use these tools just once.
3.Applying Sealer. Ensure you examine the sealer on a little patch of flooring before painting the floor. This will definitely show if the floor is clean or if there continue to be imperfections which should be repaired. Irregular density in the concrete may possibly lead to a blotchy appearance which may be unwelcome. Put on the sealer utilizing a paint roller with the extension handle. Begin in a back corner and work your way out of the place you are taking care of. Work the sealer into the surface. Spread it in a way that all the pools are eliminated and apply a uniform coat that was relatively thin.
You will probably only need one coating to protect your concrete floors for years to come – it is well worth the small effort.
