Quartz Epoxy For Exteior Non-Slip Surface

Quartz epoxy is an excellent choice for creating a non-slip surface outside. The surface will be resistant to scratching and staining and has enough texture to prevent someone from slipping. You can use this system on ADA Ramps, sidewalks, or patios. Another added benefit of using this system is the color choices available, so you will still be able to achieve a decorative finish. Below is a photo of a concrete patio and stair we applied the quartz epoxy system to.

Considering Concrete Floors On Second Floor?

If you have a typical plywood second story and you are considering having concrete floors installed, there are a few things to consider.

First you want to make sure there are no extreme low spots in the plywood. If there are and if it is a older house you might need to reinforce the floor joist the plywood is sitting on. You probably should consider this with any other ceramic or stone floor also. The weight of concrete floors is about the same if not less then installing ceramic tile and hardi-board. So if second story in your house is qualified to accept ceramic tile on the second story you will be ok with having concrete floors.

The next thing is you should not use self-leveling overlay material to get your concrete floors. This material is brittle and will crack excessively when the plywood moves a little bit. If you need guidlines on how to install concrete floors on a second story follow the link http://mvlconcrete.com/blog/upstairs-concrete-overlay-acid-stained/ . If seen many people try to use self-leveling material and then they have a huge mess to clean up when it fails.

The first concrete floor we did on a second story was about 5 years ago, and so far there has not been any major cracking. There are a few hairline cracks that are not opened up; you mainly see the crack because of the color on the surface. So don’t expect the concrete floors to have minor cracking.

If you have any questions or are looking for someone to install concrete on the second story of your house please feel free to email me at mvlconcrete@yahoo.com or call 210-422-6116.

 

Modern Concrete Floors

This week we had a job that consisted of removing tile and then polishing the concrete underneath the tile to create a modern concrete floor. When we started removing the tile floor we realized the tile was sitting on a mud-base that was 2″ thick. Instead of removing the tile and the mud-base we prepped the tiles to receive a self-leveling cement topping. After we poured the new concrete floor we sealed the floor with a water base sealer.

Can You Resurface Concrete With Paint On The Surface?

A lot of people ask if you can resurface a concrete floor that has paint on it.

When resurfacing concrete you want to make sure majority of the paint is off the floor. Most resurfacing products will bond to paint, but if the paint is not bonded to the concrete well, it will start to flake off along with the resurfacing material on it.  It is always good when planning on resurfacing concrete is to run a floor scrubber with heavy grit sandpaper, this will help remove all of the loose paint from the concrete. If you have access to a floor grinder, this will be the best option for prepping for the resurfacing material.

 

 

Spalled Concrete Repaired & Resurfaced

This concrete entrance way had a very big area delaminating. Before we begin to repair the concrete we have to check to see if there are any hollow spots in the concrete. We check by banging a hammer or running chains over the surface of the concrete. This concrete had a lot of hollow spots that were chiseled out.

You can notice in the picture above the edges are cut 90 degrees, this is because you do not want the repair mortar to be feathered out at the edges.

After the concrete has been resurface you apply a concrete stain to add color to the newly refinished concrete.

 

Concrete Resurfaced Stained & Sealed

This job consisted of removing glued down wood flooring, grinding Saltillo tile, grinding concrete, resurfacing an inclosed exposed aggregate patio, resurfacing the concrete and Saltillo tile to make a continuous floor, staining the concrete grey, and sealing the floor.

Stained Concrete Overlay in San Antonio

Concrete overlays are a great way to cover up concrete that has a lot of cracks or divots; after overlaying the concrete, you can apply a broad range of colored concrete stains.

The work required for this particular job we have finished included; grinding the concrete to create proper surface profile, filling the cracks with a repair epoxy, overlaying the concrete with a white micro-topping, staining the concrete with a grey stain, and then sealing the overlay.

Below are a few photos of the stained concrete overlay job we completed in San Antonio, Tx.

Resurfacing Old Concrete

There isn’t just the option of tearing out and replacing old worn down concrete. You have the option to use a modified-polymer cement to resurface the concrete, just as long as the concrete is structurally suitable.

Typical concrete resurfacing applications are used for restoring concrete that has been eroded, coated with a paint that is peeling off, concrete with a bad surface finish, concrete with shrinkage cracks, and spalled concrete. After the concrete has been resurfaced it can then be either sealed the way it is or the concrete can be stained using an acid stain or dye.

The proper steps for resurfacing concrete to insure a good bond are:

  • Grind concrete to produce a profile
  • Resurface concrete with a rough coat
  • Resurface concrete with a smooth coat or rough coat for a second time
  • After resurfacing cement has dried sand area smooth
  • Acid stain or dye the resurfacing cement
  • Seal resurfacing cement

Concrete resurfacing can be done inside and outside and the product we use is very durable for heavy traffic applications such as retail stores and parking garages. It can be applied with ether a smooth finish, skipped troweled finish, or a sand finish for exterior applications.

Upstairs Concrete Overlay & Acid Stained

You can have stained concrete floors on a second story of a house, even if it has wood subfloors. The process consists of laying building paper, nailing metal lath, filling the metal lath with a repair mortar, apply modified-polymer overlay, acid staining, and sealing.

The modified-polymer overlay will actually bend and give some without cracking; since the cement is mixed with a polymer, which is like a liquid rubber. The weight of the total process is not anymore than laying tile on the second floor. The total thickness is about 1/4 of an inch.

Below are photos of the process taken to complete this job.
