Concrete Skim Coating: Essential Considerations
When embarking on a concrete skim coating project, it’s crucial to keep these key factors in mind to ensure a flawless finish and long-lasting results.
Concrete Condition and Type
Not all concretes are created equal! Before grabbing your mixing trowel, assess the condition of your concrete. Is it old and cracked? Fresh and blemish-free? Different concretes may require specific types of skim coats and preparation.

Experienced hands can wield the trowel with precision, creating a smooth, level surface that looks like a pro did it.
