Preferred concrete slab seal for oil spills

Preferred concrete slab seal for oil spills

Preferred concrete slab seal for oil spills

(OP)
Hi everyone,

What's your preferred way of sealing a concrete slab on grade subject to occasional oil spills (truck vendor)?
Most of the time polished concrete + hardener works for me as it gives a smooth finish, but so far oils spills have not been a concern (they clean them with an oil stain remover)

Is there some way to avoid noticeable spills without an epoxy or similar coating without maintenance?

Kind regards.

RE: Preferred concrete slab seal for oil spills

Trouble is with coating concrete, most of the good, reasonably priced, coatings, like epoxy, are darn slippery when exposed to oil or water. If you don't mind that, you're fine. You can roughen up epoxy by casting grit into it, but now it will be harder to clean.

RE: Preferred concrete slab seal for oil spills

You might have a look at Concrete Sealer Prosoco SLX 100. It is a silane sealer that also resists oil. You can also check with companies that produce Cure/Seal/Hardeners, they can be used on existing concrete as well. These are less expensive, provide dusting resistance and may have moderate oil resistance. Clear coatings will darken the concrete quite a bit, making lighting more important. High Molecular Weight Methacrylate (Bridge Sealer) is probably the lowest viscosity "barrier" coating. It tends to darken the concrete & have a slightly purple hue (Cobalt napthanate) & a yellow sheen. Good 100% solids epoxy healer-sealers are Sikadur®-55 SLV & Chemco Systems 186 Epoxy Healer Sealer. Finally in the pigmented category, a water based epoxy will give you a thin pigmented top coat with surprisingly good chemical resistance. Since there are a limited number of suppliers of WB epoxy raw materials, nearly all are going to be good because the sealer/coating manufacturers won't be straying from the recommended formulation. PS. Just about any primer can do equal duty as a sealer.

Good summary epoxybot... you may have included some siloxanes... a heavier molecular weight material... but, most tend to be real slick when wet or coated with spillage, and, mostly environmentally 'unfriendly'.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
