When embarking on a flooring project, ensuring a dry and stable subfloor is critical for a long-lasting finish. One common question we hear at Floormart is, "Is liquid DPM any good?" The answer depends on the project requirements, but liquid damp-proof membranes (DPMs) have become a go-to solution for professionals and DIYers alike due to their versatility and effectiveness. In this guide, we’ll explore the benefits of liquid DPMs and why they’re a reliable choice for moisture control in flooring installations.

What Is Liquid DPM?

Liquid DPM, or damp-proof membrane, is a liquid-applied coating that forms a waterproof barrier on subfloors like concrete or screed. It’s designed to prevent moisture from rising through the floor, which can damage floor coverings like tiles, vinyl, or wood. Unlike traditional sheet membranes, liquid DPMs are easy to apply, often with a roller or brush, and can be tailored to different thicknesses depending on the level of moisture protection needed.

Benefits of Liquid DPM

Effective Moisture Control - Liquid DPMs excel at suppressing residual moisture and combating rising damp. They’re particularly useful for cementitious screeds with up to 98% relative humidity or calcium sulphate screeds with up to 90% humidity. This makes them ideal for environments prone to dampness, such as basements or commercial spaces.

Fast Application and Curing - Many liquid DPMs cure quickly, often within a few hours, allowing flooring projects to progress without long delays. This is a game-changer for time-sensitive renovations in retail units or warehouses.

Versatility Across Projects - Whether you’re working on heated screeds or high-traffic industrial floors, liquid DPMs offer adjustable thickness for customized protection. They also resist water, grease, oil, and dilute acids, ensuring durability in demanding settings.

Seamless and Flexible - Unlike sheet membranes, liquid DPMs create a seamless barrier, reducing the risk of leaks or weak points. Their flexibility makes them suitable for a variety of subfloors and flooring types.

Is Liquid DPM Right for Your Project?

Liquid DPMs are an excellent choice for projects requiring robust moisture protection and quick turnaround times. For instance, products like the Kelmore One Coat DPM Fast Waterproof Membrane offer rapid curing in about 4½ hours and can handle high humidity levels, making them ideal for commercial and industrial applications. Always ensure proper surface preparation and follow manufacturer guidelines for the best results.

In conclusion, liquid DPMs are a highly effective solution for moisture management in flooring projects. Their ease of use, durability, and fast curing make them a favorite among contractors. For a professional finish that stands the test of time, consider incorporating a high-quality liquid DPM into your next project.
