Cement resurfacing is extremely important and might be tricky sometimes, especially if you live in a hot, dry area like Los Angeles. Resurfacing cement wrong could lead to a variety of problems with your floor. These problems include deterioration, peeling or chipping away, and fading of the colors. Therefore, in this blog post, we’ll tell you our tips and tricks on how we resurface your cement perfectly.
1) Surface Preparation
Surface preparation is the first, and most important, phase in the process of resurfacing concrete. When preparing your surface, your concrete needs to be properly cleaned. We always make sure to strip off any type of coating that is covering your floor (paint, tiles, old stamps or overlays). We then ensure there is no dirt, dust, oil, or any other type of contaminating particles before resurfacing your floor. If this step is skipped then any decorative coatings you add to your floors in the future won’t bond to the concrete to their fullest potential.
2) Sealing Process
Sealing is the surface-to-surface joining technique of materials using a substance known as sealant. Epoxy concrete sealers are one of the most durable sealers perfect for garages, high traffic retail environments, and lofts. The substance transfers the forces from one adherent to the other. The substance used for sealing is known as a sealant or sealer.
Sealing is the last phase of the concrete resurfacing process. The sealer is in charge of doing two things. It makes your new floor shine, and serves as a shield to your concrete. Sealing is extremely important when resurfacing cement floors. It is important because it protects from UV rays, foot and vehicle traffic, and from day to day dirt and grime. Solvent-based sealers usually provide greater protection; when we are resurfacing a cement floor that is exposed to tons of sunlight we use at least two coats of sealer. This way your cement floor is better protected from the dry, hot Los Angeles climate.
How We Apply The Sealer
Another important tip we use when sealing and resurfacing cement is to spray the sealer instead of rolling it. Many people prefer rolling the sealer with a foam roller when applying the final protective coating. However, when it’s too hot out, rolling may lift the sealer only after the second or third time it goes over a certain area causing imperfections. This can ruin all of the hard work we’ve put prior to sealing by leaving ugly spots throughout the surface. A better method of applying the sealer if you live in a hot, dry area like Los Angeles is with a pump sprayer, instead. Applying it with a pump sprayer will unfortunately increase your cost (since you can only spray sealer once with every pump sprayer because it gets clogged up), but it will definitely save you a ton of stress and frustration. An evenly sprayed coat of sealer is normally heavier than a rolled one too, which gives better protection and fewer future problems. Depending on the amount of traffic and sunlight exposure your cement floor receives, it may need to be re-sealed every 5-8 years.
3)Applying The Overlay
Since we live in a hot, dry area we apply the overlay during the coolest times of a day. When it comes to decorative concrete, we never start working right after sunrise. We wait until the morning dew has dried up, which normally happens between 8AM and 9AM. Unless there’s a heatwave, which means we are going to get a milder temperature until about 11AM. Still, starting work at 11AM gives us enough working time to coat most projects less than 2,000 sq. ft. After this window, the second best bet is to start a little before the sun sets. If by any chance you want to work on resurfacing your cement alone and want to apply the overlay at night make sure you have bright lights where you are working. Another important tip we follow is mixing the overlay with cool water. When we mix our bucket of overlay, we never leave it exposed to direct sunlight. It’s better to carry it every time you need to pour some down than to rush while applying it.
