There are some options out there when it comes to cleaning and sealing concrete pavers. One can either hire a professional paving contractor to do the job or do it themselves. Most of the time a DIY project is not only easier, but saves money as well. If one does not have any experience with concrete paver sealing or paving, then the best option is to hire a professional paving contractor. One thing to remember when hiring a contractor is that it pays to shop around.
Cleaning and sealing pavements can be tricky at times, especially if doing it yourself, especially if you’re inexperienced in this line of work. The wrong procedure can lead to potholes in the pavement, cracks, and unsightly damage. This is where hiring a professional paving contractor would be beneficial. The contractor will be able to give the correct advice on how to proceed with any particular project. One thing to keep in mind is to buy enough joint sand, or seal sand, to go along with the pavers being used in the project.
Different Sealing Options
There are many different chemical additives in today’s paints and flooring. It is important to know the difference between the types of chemical additives out there. Depending on the type of material used, some may require a different form of chemical agent for proper sealing.
In general, a bonding agent like petrolatum, mineral oil, or ethyl acetate is needed for normal wetting and setting of concrete pavers. However, they do not have the ability to prevent hydrostatic pressure once puddles start to form underneath the paving. For this reason, these additives are no longer recommended for sealing paving materials. In order to achieve hydrostatic sealing of concrete pavers, one needs a liquid sand stabilizer.
The product most commonly found in the industry is hydroxyapatite, also known as HAP. It is made up of powdered talc and mica, which are suspended in water. The combination of these ingredients creates a gel that can adhere to any surface, including paper, thereby achieving hydrostatic sealing of the paving. As of the latest, no adverse effects from this substance have been reported.
Another common ingredient of HAP is polymeric sand, also known as SPT. The product has the same consistency as SPT. It is often mixed with talc and is sometimes added with some form of binding agent. This is usually done in order to achieve a homogenous appearance of the finished paving.
These two most common products for Pavers sealing and cleaning have their own advantages and disadvantages. For one, there is the SPT, which is the more expensive of the two. As it is a synthetic material, it is more expensive than natural pavers. However, since it mimics the look and feel of natural material, it offers a lot of benefits when it comes to maintenance and repair. It is also resistant to the effects of weather and termites.
Hydroxyapatite is used mostly for repairing cracks in paper because it seals the material, making it impervious to moisture. The material is also resistant to acid and alkali and therefore poses little or no threat in terms of wearing out, cracking, or other forms of damage. Polymeric sand, on the other hand, is meant for pre-paving purposes and is commonly used for irregular surfaces like driveways. However, it is not capable of sealing and finishing concrete and thus is mostly used for areas like sidewalks and walkways.
To seal pavers, you need to apply a mixture of cement, sand and water. Pavers are not good candidates for this kind of preparation because they are already porous. The solution has to contain an acidic ingredient like vinegar to prevent pore seepage. This is done in order to prevent the concrete from drying out. Once the application is done, it will last for a long time because the water content of the mixture is very low.
You can also use a formulation that combines silicone and caulk in order to seal and finish your paper. These two compounds are effective against most kinds of acids and will not leave any hazardous residues. The pH of these materials also ensures that the pavers are not stripped off from its masonry joints. They are best suited for pre-paving and irregular surfaces like driveways, walkways and patios. They also work great for sealing the pavers of driveways and for pre-lighting them.
If you want to seal pavers and keep them looking new for a long time, you should use an alkaline solution. This formulation will ensure that the concrete is sealed and protected. It will also add to the longevity of the material. This alkaline sealer does not add wear to the material and it works well with all types of concrete and pavers.
