How To Resurface Over Exposed Aggregate Concrete

Video How to restore surface on exposed aggregate concreteAs a building owner, you may be faced with the decision of what to do with your old concrete, and you need some specific resurfacing ideas. For example, you may need to refurbish your concrete yard. Most contractors will tell you it needs to be removed and replaced – but is this really necessary? The problem is that there is no easy way to remove old cement after it has hardened, so you need to get creative if you’re looking for a cheaper, less intensive solution. Can exposed aggregates be resurfaced? Yes, it can, and I will cover 11 different ways to cover exposed aggregate concrete in this blog post!

Option one: Use surface coating

This may be the best option if your concrete has small cracks or holes as it will keep water out of them and prevent major damage from freezing temperatures (although this is not a 100% guarantee). ). It’s also an inexpensive way, although I still recommend one with sealing properties for more effect. Some of the pros and cons of this approach are:

Advantages:

• Easy to apply and affordable
• Cover cracks or small holes in concrete, preventing damage from freezing temperatures if done correctly

Defect:

• Surface coating may not be sufficient for larger repairs.
• The surface is still vulnerable to water seeping through and can eventually cause a breakdown of your floor below! This will also happen much faster than you might think because there are variable sealant properties (depending on what you use) included with this type of option.
• If you have any electrical wiring, plumbing, heat pipes under the concrete, then I recommend avoiding relying on these coatings.

Option Two: Uses a system of coatings and sealants

Use a putty and sealant system to create the look of concrete without removing the whole thing first, then add new aggregate where you need it (usually around doors or other areas). other navigable areas). The rugs are durable enough that they won’t blow away after windy days – but they won’t work in large areas and they must be replaced or repaired when you need more synthetic material. It is more expensive than removing old concrete and installing new aggregate, will take less time to complete (saving you money) and requires less maintenance. concrete – although there are some newer options in this category, so be sure to ask your supplier what grade they recommend for these needs. Another disadvantage of using a carpet system with sealant is that sometimes applying too thickly can leave an uneven surface texture if applied over rough surfaces such as tiles while any imperfections are present. Anything in the background may be exposed because the carpet will not cover it well. .

Option three: Use a covering system

Use a cover system designed with smaller quantities in mind at a time – this means it’s not expensive up front as there are no delivery fees (also good if your area doesn’t allow delivery). general goods). The advantage is that it can be installed in a day or two and the surface is usually very smooth. The problem is that this method will only last for about six months before needing to be re-wrapped – this can still work well if you want something temporary while your property is renovated.

Fourth option: Add a top overlay

Add a top coat – you can use shredded bark, crushed wood chips or other materials to create this look. You need one of these options so that the whole is not only covered but protected from erosion and damage (it will last longer than just sitting out there unprotected), and that’s it. is a great way to add some color and texture. The good thing about this coating is that it will last a very long time, but the downside is that you will need to maintain the coating on your surface for it to look its best.

Option year: Add cutter

Add paving stones or stones on top of the existing aggregate. While most contractors say to scrap and start over, others say that as long as the structural integrity of the existing slab is fine, you can use exposed aggregate as a base. to add to dry paving stone or pavers or mortar. Read more: how to do it. To draw a golf ball on paper, an important factor to remember with this approach is that the initial exposed aggregate may already be at the required height, so make sure you account for a 3 height gain and 1/2 inch or area. This is important to consider for existing stairs and doors, etc. The advantage of this method is that it is the most efficient in terms of budget and time. The downside is that since the aggregate is below ground, there will always be a slight problem with water seeping into the paving seams due to runoff of the underlying concrete surface.

Sixth option: Cover with thin strips of bricks

Cover with thin strips of bricks. This is a great option if you want an exposed aggregate concrete cover, but also like the look of the old style (or don’t have much of a budget). With this approach, keep in mind that it will take time for moisture below and around the brick or block above to seep into the exposed aggregate below, so you need to make sure that the moisture can escape.

Seventh Option: Paint it

Paint: If you’re on a tight budget and don’t need major repairs, paint could be the perfect choice! It will definitely cover the aggregate concrete so your floors look like new. The downside is if there are any spills or stains as they will not come off easily compared to other coatings. However, if you decide to go with this option, make sure not to use rubber paints – for some reason they have never worked well for me in terms of durability (I always end up discarding them). again within a few months) !! ! So I recommend using oil paints instead – just keep in mind that these can contain many chemicals that can be harmful to the environment, so make sure you’re doing your research and choosing your options. has an environmentally friendly rating.

Eighth choice: Use bricks

Brick: Another option for covering aggregated concrete is brick. You can install them above, above or in front of old paint. The downside of any type of tile is definitely the budget as they cost a bit more than others like paint but they are also cheaper than new flooring. out of reach.

Option Nine: Flagstone

Coat them with flagstone or other similarly shaped stones but cover them with grout to give the floor a chic Italian look.

Option 10: Artificial grass

Cover with artificial turf and then top it off with a layer of concrete, large flagstone or other similarly shaped stones to add texture to the turf that looks more natural and will last a long time without need maintenance.

Option Eleven:

Cover with concrete paving, large flagstone or other similarly shaped stones to add texture for a more natural look and will last long with no maintenance.. This is your best bet. you as this is the least expensive and most practical option Finally if you don’t want any of the above at least make sure your overall is clean so everyone can see where they are going – This will help them avoid slipping or falling on rainy days as well!

Frequently asked questions for contact aggregate concrete coating

Read more: How to become a dom Can you re-fill exposed aggregate concrete? Exposed aggregate concrete is a decorative finish in which the top layer of concrete is removed to reveal the colorful aggregate beneath it. So, if you have an existing concrete structure that is solid, you can use exposed aggregate concrete to make the surface look like exposed concrete again. First, mix a 1:1 solution of muriatic acid in water. Spray the solution onto the surface, then scrub away the acid with a stiff-pointed anti-acid brush. More than one application of acid may be required for the right look. To avoid damaging other surfaces, grass and/or vegetation, you may want to consider acid mixing for flow control. These sealants, typically acrylic resins or resins with film forming properties, are ideal for protection against dust, scale build-up, freezing damage, fire, explosion, abrasion and stains. Aggregates will also look richer and more colorful with the sealant. Is contact aggregate concrete more expensive? Since contact aggregate requires more material and labor than standard aggregate, it is more expensive than standard aggregate.

Additional considerations

Patch An Option?

If the problem with your surface is that it has become patchy with some parts of the whole flaking off into patches, one option worth considering is patching a problem area rather than covering it with something new or get rid of it all together. You can patch damaged areas using epoxy mixed with new replacement aggregate to restore an even surface.

Add Pavers or Stones on top of an existing composite

While most contractors say discard and start over, others say that as long as the structural integrity of the existing slab is fine, you can use exposed aggregate as a backing layer. added to dry paving stone or pavers or mortar. With this approach, an important factor to remember is that the initial exposed aggregate may already be at the required height, so make sure you account for a height or area gain of 3 and 1/ 2 inches. This is important to consider for existing stairs and doors, etc.

Bonding new cement base layer on existing aggregate layer

This might work, but it’s not trivial and involves several steps. Existing aggregate must be sufficiently bonded to the existing cement to allow for the steps involved (test by applying pressure washing to the test area at 3500psi to see if the existing aggregate has sufficient keep or not). If the existing surface is hard enough, cleaning and etching is required prior to the application of a new cement coat. Check out this forum post for more details.
