Although concrete is a solid matter, it is a porous material which means it absorbs liquids just like a sponge. Different liquid substances may seep into concrete from water to vehicle oil, greases and grime. Once the concrete has absorbed these liquids, it would be very hard to remove them. Sealing your concrete prevents liquid substances to penetrate it is pores, in the long run prolonging the life of the concrete surface. How do concrete sealers work as a protective barrier? A concrete sealer changes the calibers of the concrete’s surface so that when water comes into contact with it, the water atoms form tiny blobs on the surface rather of penetrating it. Then, the water droplets just roll away from the surface. Sealing gives concrete the same shelter versus oils and grease so even these normally hard-to-remove stains become easy to clean. It likewise protects versus de-icing salts so sealing is particularly crucial on exterior concrete surfaces that go through freeze-thaw cycles. It likewise does away with the problem of mildew penetrating the cement, which may leave black stains on the surface over time. How does it affect the concrete’s appearance? Sealers commonly impart sheen to concrete surfaces drawing out the rich colours of ornamental concrete. Any ornamental concrete finish will look much better when sealed. Exposed aggregate concrete will unquestionably gain from sealing because it enhances the beauty of the ornamental aggregates (i.e. pebbles and little stones) in the concrete. A tinted sealer may be applied to a plain gray slab or ornamental concrete to add colour. Regular application of a quality concrete sealer will make your concrete more immune to fading and wear. How oftentimes ought to concrete sealing be done? There is no precise rule to this because various constituents are involved, mainly the type and quality of the product you used, the emplacement of the area and the conditions the concrete is exposed to. A sealer, depending on the precise product, may last from 1 to 3 years. Basically, you ought to seal your concrete as soon as you detect the coating is starting to wear away. You ought to also reseal coloured concrete as soon as you see the need for it because delaying the work may result to a slight fading of colour. You ought to consider traffic and weather factors. Naturally, concrete surfaces that get a lot of vehicle traffic and is exposed to sunlight will wear rapidly and without delay than, say, a covered concrete area with moderate foot traffic. This is why concrete driveways are ordinarily sealed more ofttimes than patios or sidewalks. Recommendations: Seal concrete driveways once a year, ideally for the duration of fall to prepare it for winter conditions. It is idealisti to re-apply clear seal on coloured concrete that get heavy traffic or is exposed to harsh winter conditions each 1 to 2 years. Seal other exterior concrete surfaces (plain or coloured) that do not get vehicle traffic each 2 to 3 years. For interior concrete floors, it’s okay to seal them once but utilize wax coating periodically. With periodic concrete sealing, the next coatings only need quick and thin applications. So, will have to you seal concrete? While the gains of sealing are apparent here, galore humans still do not seal their concrete. Some say it’s not necessary if you live in a place that has a mild climate or don’t get much rain. But the truth is sealing improves the overall aspect and life of all types of concrete disregarding of the location. So, if you want to protect your investment, there’s no question to it – you ought to seal your concrete. |
