Getting Started

How difficult is it?

Transforming your existing countertops with a GlassCast Countertop Kit is far easier than you might imagine and certainly an entirely realistic project for any keen DIYer.

For a small sized kitchen with around 4m of worktop (2sqm area), the whole process is likely to take around 3hrs, much of which is prep. Certainly it’s far quicker, and far cheaper than replacing the work surfaces themselves!

The GlassCast countertop tutorial covers the whole process from start-to-finish and has been made to be as honest and realistic as possible. If you have any questions or hesitations after watching the video, please get in touch with our friendly team and we’d be only too happy to advise you.

What else will I need?

In addition to the resin and pigments included in the kit, the other things you will need to complete your countertop transformation are a hair-dryer, some form of barrier tape and a few ancillaries like mixing buckets and abrasive paper.

To make life easy, a complete set of all tools and ancillaries needed (excluding hair dryer!) is available in our accessories section and just pick up what you don’t already have.

Scratches and Heat Resistance

Although a GlassCast resin countertop look just like a natural stone countertop, it is still a resin surface and will need to be treated properly in order to keep it looking its best.

Scratch Resistance of Epoxy Countertops

In general, epoxy resin is a very hard-wearing material and will stand up very well to normal daily use. Even still, you should use common sense and always use a chopping board avoid cutting or chopping directly on the surface or dragging sharp or abrasive things around on it.

If you do find that your worktops have accumulated some scratches over time, the great news is that they can be quickly restored by flatting with a fine abrasive paper and then polished back to their original gloss with a polishing compound.

Heat Resistance of Epoxy Countertops

Whilst different manufacturers (many from the US) make various claims about the heat resistance of their epoxy resin, we have never found a countertop resin with better heat resistance than GlassCast. That said, it is still possible to lightly mark any resin countertop if hot plates or very hot drinks are placed and left directly on it. The good news is that these marks do tend to ‘bounce back’ after time, often leaving no mark at all or can easily be polished out if needs be.

Just like a laminate or wooden worktop, very hot objects - such as a pan taken directly from the oven or off the hob - should never by placed directly onto the resin surface because they will mark it. However, if this were to accidentally happen, the results are usually less obvious than they would be on a wood or laminate worktop and can generally be rectified more easily.
