Question 1

What is Mapei Plastimul DPM 20L and what does it do?

Accepted Answer

Mapei Plastimul DPM 20L is a moisture-activated, polyurethane damp-proof membrane delivered as a water-based acrylic emulsion. It forms a flexible, fibre-reinforced waterproofing layer that can seal surface cracks, protect substrates such as concrete, masonry and bituminous materials, and is suitable for use under screeds, tiles, and carpets in both interior and exterior applications, including wet areas.

Question 2

What substrates can Plastimul DPM be used on?

Accepted Answer

It can be applied to concrete, masonry, and bituminous substrates, providing a flexible waterproofing membrane that helps seal and protect these surfaces while bridging small surface cracks.

Question 3

How does Plastimul DPM work and what makes it special?

Accepted Answer

Plastimul DPM is a highly elastic, fibre-reinforced membrane formed from a moisture-activated acrylic emulsion. It detects and fills cracks and cures to a resilient waterproof layer, offering crack-bridging capability and breathability for damp environments.

Question 4

What are the recommended applications for Plastimul DPM?

Accepted Answer

It’s recommended for use under screeds and beneath floor coverings like tiles and carpets. It’s suitable for wet areas such as bathrooms and kitchens and can be used in both interior and exterior environments to provide a waterproofing base.

Question 5

How do I apply Plastimul DPM (tools and technique)?

Accepted Answer

Apply Plastimul DPM with a brush, roller, or paint spray to achieve a uniform membrane. Ensure the surface is clean and dry, and apply evenly to build the required film. Tools and membrane cleanup can be done with soap and water.

Question 6

Do I need any surface preparation before applying Plastimul DPM?

Accepted Answer

Yes. Prepare the surface by cleaning it to remove dust, oils, and loose particles. Inspect for cracks and surface imperfections and fill them as needed. The substrate should be sound and dry before application. In many cases priming is not required, but always follow the product data guidance for best results.

Question 7

How long does Plastimul DPM take to cure and when can I tile or finish the floor?

Accepted Answer

Plastimul DPM cures quickly to form a durable waterproofing layer. Cure times depend on temperature, humidity, and film thickness. Follow the product data sheet for the recommended cure times and for when tiling or finishing can begin.

Question 8

Is Plastimul DPM breathable and suitable for damp environments?

Accepted Answer

Yes. The membrane is breathable, allowing moisture vapour to escape while forming a protective waterproof barrier. This makes it well-suited for damp areas where moisture management is important.

Question 9

What safety precautions should I take when using Plastimul DPM?

Accepted Answer

As a water-based acrylic emulsion, use standard PPE such as gloves and eye protection. Ensure good ventilation during application, wash skin with soap and water if contact occurs, and clean tools with soap and water. Store the product in a cool, dry place and keep it away from freezing temperatures.

Question 10

Can Plastimul DPM be used under ceramic tiles and carpets, and are there any limitations?

Accepted Answer

Yes, Plastimul DPM is designed for use under tiles and carpets as a waterproofing base. It is important to ensure the substrate is suitable and compatible with the membrane. Do not use where there is continuous potable water exposure unless specified by the data sheet.

Question 11

How does Plastimul DPM compare to other damp-proof membranes available on Fepy?

Accepted Answer

Plastimul DPM is a moisture-activated, flexible, crack-bridging membrane designed for ease of application and damp areas. For alternatives on Fepy, see products such as Mapei Plastimul DPM 10L (URL1) and Mapelastic (URL2).

Choose based on project size, substrate, and required cure and installation characteristics.

Question 12

Which alternative on Fepy should I consider for different project scales or substrate conditions?

Accepted Answer

If you’re weighing options against Plastimul DPM 20L, you might look at Mapei Plastimul DPM 10L for smaller jobs or Mapelas Mapelastic (or other compatible waterproofing membranes) for different substrate conditions or performance profiles. Check their respective pages on Fepy to compare coverage, cure times, and suitability for your specific substrate and finish.
