There are several resins which can be used for casting which include polyurethane resin, polyester resin, and epoxy resin. While the former two have many uses and tend to be cheaper, epoxy resin is the one which offers the greatest degree of durability.
A question which is frequently asked in relation to epoxy finishes is whether or not it is possible to apply a new or additional coating to an existing one. The reason this query often arises is that using an epoxy coating involves a fair degree of preparation and for the epoxy coating to be created, two separate solutions need to be mixed.
There are also considerations in terms of setting and drying time.
If you are considering renewing the floor in your garage, then one of the best ways it can be done is by using an epoxy coating. It has proven to be one of the most durable and hard-wearing flooring finishes available, while at the same time it can help make a garage look for more modern and presentable than boring, grey concrete.
