Paver Stone Installation – Pros and Cons of Sealing

You will most commonly seen paver stones in the lining of patios, walkways, as well as driveways of houses. The material used to make these stones can range from stones and bricks to plain concrete. In addition to varying sizes available in the market, these different materials also have varying degrees of durability and longevity. In order to ensure each lasts as long as possible, it is good to use a sealant which will preserve colour as well as materials. Sealants however should be redone once every two or three years. Additionally, make sure that the sealant you use is right for the material that is your paver stone. Listed below are a few pros and cons:


  1. Weather protection- using sealants after installing paver stones is a huge advantage against weather conditions weather it is rain, snow, or heat. If paving stones are not sealed, water can seep through and corrode their foundation. This in turn will lead to cracks in the stones. A sealant on the other hand will prevent water seepage and prevent erosion and cracks in paving stones.
  2. Longevity and durability- this point clearly ties in with the previous one. When the sealant protects paving stones from damaging weather conditions and subsequent wear and tear, the longevity and durability is increased. Sealants also prevent grass and weeds from growing between the cracks of the paving stones.
  3. Appearance- sealants help protect the aesthetic appeal of the pavement by blocking UV rays and preventing the colours of the pavement from fading


  1. Cost- there are several varieties of sealants available in the market. Bear in mind that a cheaper sealant can affect the quality and functionality as it will be thinner. This does not mean you have to buy an extremely expensive sealant. Opt instead for a sealant that will last long and provide you with high protection. For example, if you have to use a sealant on concrete driveways or pathways, the more expensive one is definitely the better option as it has higher longevity.
  2. Safety measures- once you have installed the paver stones, you will have to move on to the sealant. However, before handling this sealant, it is necessary for you to wear protective covering like gloves as well as other things like shoe covers as well as masks. If the sealant comes in contact with your skin, you could have a tough time getting rid of it. Now when it comes to the environment, there are certain detrimental effects as well. For example, the sealant can make surfaces slippery and so it would be a good idea to seal paver stones when it is not raining or snowing. Additionally, the chemical composition of the sealant could contain urethane or acrylic bases and this is extremely dangerous in the case that there is a fire. To avoid any accidents, make sure that when you are applying a sealant, the area is well-ventilated.
  3. Reapplication- when you use a sealant, there is a high possibility that you will have to constantly re-apply it, incurring more costs.
