The #1 Epoxy Stone Installer in the Northwest for 9 Years

Frequently Asked Questions

How well does it hold up?
EPOXY STONE NORTHWEST uses a premium quality, two part, high-strength epoxy, which is even stronger than the stones themselves. The stone is premixed with epoxy on site. The mixture is then troweled by hand, leaving a smooth seamless surface. Epoxy Stone overlays have been used for over 25 years in Canada and the United States. Freezing water does not displace the stone. With a minimal maintenance you can enjoy and trust the installation for a lifetime.

Is EPOXY STONE maintenance free?
Nothing is totally maintenance free. EPOXY STONE Overlays, however, are as close as it gets. For cleaning of exterior applications, just sweep it or use a pressure washer. The surface is stain resistant, oil drippings can be removed with a citrus degreaser and scrub brush. You can use a pressure wash if it needs it. Compared to concrete it is far easier to keep clean. Mildew will not grow on the surface and moss has a difficult time as well. We recommend a pressure wash at least once a year for a thorough cleaning.
Ultra-violet light causes the surface shine to slowly fade. A simple recoat with epoxy (applied with a paint roller) will restore the shine. We recommend a re-coat of epoxy every three years to keep it looking like new.

For interior floor the overlay is practically maintenance free. It only needs a vacuum cleaner and a wet mop.

Does it crack?
EPOXY STONE hardens to a compressive strength of 4500 PSI. A 20 % elasticity allows for some surface expansion and contraction. If the concrete underneath cracks due to a ground movement or earthquake, the EPOXY STONE surface will crack with it. However we have a distinct advantage over other products, we can repair it easily by reinstalling the same stone mixture at a minimal cost.

Why doesn’t it grow mildew?
The EPOXY STONE forms a porous surface which allows rain or moisture to pass through and drain with the grade. Water doesn’t puddle up, which means the surface dries fast and is resistant to mildew.

Is it environmentally safe?
Yes, The two-part epoxy becomes solid by molecular action only. It does not rely on the evaporation of thinners or moisture to cure. In fact, the epoxy will cure without air, even under water. There is a slight smell during installation and its curing process. After 1 day there are no odors left.

Why is it anti-slip?
To insure good traction we disperse a liberal amount of fine silica sand which adheres to the surface as the epoxy hardens.

What is the Guarantee?
We guarantee every installation of EPOXY STONE Overlays for two years for workmanship and material. We cannot guarantee against cracking as a result of ground movement or settling.

Is it cheaper than breaking out the old concrete?
The cost of Epoxy Stone is equal or less to installing washed aggregate and far cheaper than stamped concrete. Although the installation of Epoxy Stone is an excellent alternative to get rid of your ugly concrete, it is not a cheap “cover-up solution” such as paint or tar. The Epoxy Stone overlay gives a totally different and distinctive look to your house. It enhances dramatically the curb appeal of your home and brings more value to it.

What if there are cracks in the old surface or deteriorated expansion joints?
We pressure wash the old surface with 3200 PSI and fill the cracks with epoxy to seal them. Deteriorated expansion joints are taken out and the space is filled with epoxy. We then coat the whole surface with epoxy before we apply the mixture. This seals it from moisture and gives a good bonding surface to the EPOXY STONE mixture. Over expansion joints we apply a V-grove to prevent cracking.

How long does an installation take?
Most jobs (also driveways) are installed in one day. The next day you can walk on it and after five days drive on it. We cause minimal disruption and do a complete clean-up afterwards.

Can you do verticle surfaces?
Yes. We use a heavier epoxy to hold the stone in place on step faces and foundation walls. This is a more demanding process and costs a little bit more.

What does it cost?
The price is around $7 per square foot, depending on the size and condition of the job. This includes any necessary preparation work, such as crack repair, pressure washing, etc. Verticle applications on steps are priced higher.
