Now that you’ve made the investment in a stone patio, you will need to take at least minimal care. Arguably the best way to do this is to have it sealed. Sealing was developed protect the patio stones from the elements like snow and sun. It also provides a layer of protection from normal besmirching elements like mud from a garden. The important thing is that you not rely on the sealant to do all the work for you. Even if you have had a sealant applied, you should still regularly hose your stone patio down.
There are two basic variants on paver sealant: glossy and and matte. Each do the job, and your choice will depend upon whether you want a “wet” look or a “dry” look. Besides the look, there is a difference between how often the sealant must be applied: once every 2 years for glossy and once every 3 years for matte.You mileage may vary. One additional note: don’t seal your stone patio for at least a year.
You should not skimp on the price of your sealant. Some of the cheaper ones can have an effect on how the color of the stones appears. Application is not particularly difficult, but there are some things a professional will know that a DIY guy won’t. Sometimes you save more when you call a professional.
