Rumido 4 L

Rumido 4 Litre – Terrace Waterproofing Paint & Waterproof Coating

Your terrace is always exposed to rain, sunlight, humidity levels, and temperature changes, which result in water seepage, damp patches, surface deterioration, and ultimately lead to roof leakages. So, choosing the right terrace waterproofing paint will be beneficial for you to keep your surface safe from such issues.

Rumido 4 Litre by 20MCC is a polymer-based waterproof coating specially designed for use on roofs, terraces, internal as well as external walls of buildings. It has a high-bond polymer formulation that forms an impermeable layer over the surface to prevent moisture penetration into substrates.

Also, due to its application of molecular nanotechnology, Rumido waterproofing coating penetrates into pores within cementitious surfaces up to a depth of 2–3 mm, thus reducing the chances of water and moisture movement inside substrates.

Waterproof Coating for Terrace – Protect Your Roof from Water Damage

The right kind of waterproofing coat on the terrace will go a long way in minimising the chances of penetration and keeping the structure underneath safe from all kinds of moisture-related deterioration. As you know, terraces remain directly exposed to rain, especially during monsoons, standing water, direct sunlight, and changes in temperature.

This waterproof coating, called Rumido, provides an effective water-repelling property while offering a protective sheen to your terraces. From concrete to china-chip to mosaic tiles and bricks, this coat can work well over many types of structures already built upon the terraces. Also, its surface stays cool in summer, as mentioned by 20MCC – this paint reduces the surface temperature by an average of 7–10 degrees Celsius if applied onto porous construction materials.

What Is Terrace Waterproofing Paint?

A terrace waterproofing paint is a special kind of protective coating that you apply to your terrace’s roof or surface. This creates a barrier that keeps moisture from seeping through, protecting your home.

Unlike other kinds of paints used for decoration purposes, these types of waterproofing coatings have formulations specifically made to offer such protection. Now, if you want an efficient solution to protect your house from the dampness, then you need this Rumido! It is a super-durable, easy-to-apply polymer-based waterproofing coating that provides complete protection from moisture.

The high-bond polymer forms a water barrier membrane on the surface, while its formula ensures bonding with porous substrates. For achieving ideal results, proper surface preparation along with proper application should be done. Generally, this product needs 2 coats of application followed by proper curing.

Why Choose Rumido for Terrace Waterproofing?

Long-Lasting Waterproof Protection

As per 20MCC, Rumido provides you with up to 7 years' protection against water leakages. It forms a continuous water barrier due to its polymer-based formulation and protects your terrace from moisture migration.

Excellent Surface Adhesion

The need for good surface adhesion between a waterproofing coat and the substrata ensures uniform protection. The Rumido Waterproof Coating has excellent adhesiveness. It bonds well with various types of substrata such as concrete, China chips, Mosaic Tiles, Brick Bat Coba & Painted Surface. Hence, you will find this product appropriate to apply over different kinds of your terrace’s surface already available.

Helps Reduce Terrace Heat

Because Terraces are always exposed to Direct Sunlight all Day long, they tend to get a lot more heated than other parts of your house.

However, with this product, Rumido is able to reflect the Sunlight and even reduce the Surface temperature by Up To 7–10 °C in case Of Porous Construction Materials. So, You Will Always Get Cool Surfaces Compared To Others In Hot Weather.

Protection Against Weather & Moisture

Rain, humidity, sunlight, and temperature variations can gradually affect exposed terrace surfaces. Rumido provides water repellency and forms a protective barrier against moisture.

Its formulation is designed to penetrate porous surfaces and form strong bonds within the substrate, helping limit water and moisture migration.

Suitable for Multiple Terrace Surfaces

One of the key advantages of Rumido is its multi-surface compatibility. It can be used for waterproofing applications on concrete, China chips, mosaic tiles, brick bat coba, and painted surfaces.

This makes it a practical option when an existing terrace has a surface finish that differs from standard RCC or concrete.

How Does Rumido Waterproof Coating Work?

Rumido uses a high-bond polymer formulation supported by molecular nanotechnology. The coating is designed to penetrate porous cementitious surfaces up to 2–3 mm, helping form strong bonds within surface voids. This penetration helps reduce the migration of water and moisture through porous substrates.

Once applied, the coating forms a water barrier membrane over the surface. For proper waterproofing performance, 20MCC recommends applying two coats and allowing appropriate drying and curing time.

How to Apply Terrace Waterproofing Paint?

Correct application is essential for achieving the intended performance of any terrace waterproofing paint. Follow these basic steps when applying Rumido:

1. Step 1: Prepare the Terrace Surface
   Clean the surface thoroughly before application. Remove loose paint, dust, grease, dirt, and loose particles. 20MCC recommends thorough cleaning using methods such as intense wire brushing, a high-speed water jet, or a vacuum cleaner, depending on the surface condition.

2. Step 2: Repair Cracks and Damaged Areas
   Inspect the terrace for visible cracks, damaged sections, weak areas, or other defects. These should be appropriately repaired before applying the waterproof coating. A clean, sound, and properly prepared substrate helps the coating adhere more effectively.

3. Step 3: Apply the First Coat
   Apply the first coat of Rumido using a suitable brush over the prepared surface. Allow the coating to dry for a few hours before proceeding with the next coat.

4. Step 4: Apply the Second Coat
   Once the first coat has dried, apply the second coat to achieve proper hiding and the desired waterproofing properties. Two coats are recommended for a proper waterproofing solution.

5. Step 5: Allow Proper Curing
   Allow the completed coating system to cure properly before exposing it to water or regular use. For fresh construction surfaces, 20MCC recommends allowing the substrate to cure completely and following the applicable curing guidelines as per IS 1661:1972.

How Much Area Does 4 Litre Rumido Cover?

Coverage depends on the porosity and condition of the surface. For Rumido, the stated coverage is:

• 1 coat: 55–65 sq. ft. per litre
• 2 coats: 30–40 sq. ft. per litre

Therefore, a 4 litre pack can provide approximately:

• 220–260 sq. ft. for one coat
• 120–160 sq. ft. for two coats

Actual coverage can vary depending on surface porosity, texture, condition, and application method.

Where Can Rumido Waterproof Coating Be Used?

Concrete & RCC Terraces

Rumido can be used on concrete surfaces and is suitable for terrace and roof waterproofing applications.

China Chip & Mosaic Surfaces

Its multi-surface adhesion allows it to be applied over China chip and mosaic tile surfaces, subject to proper surface preparation.

Brickbat Coba

Brickbat coba terraces can also be treated with Rumido as part of a suitable waterproofing application.

Painted Surfaces

Rumido can be applied over suitable existing painted surfaces after proper cleaning and preparation.

Common Terrace Waterproofing Problems

Terraces can develop several moisture-related problems when water is able to penetrate the surface. Common issues include:

• Water leakage during monsoons
• Damp patches on ceilings and walls
• Moisture migration through porous substrates
• Cracks and deteriorated surface areas
• Water accumulation on poorly maintained surfaces
• Paint deterioration caused by persistent moisture
• Excessive surface heating during summer

Early identification of these problems can help prevent more extensive deterioration.

Why Does Terrace Waterproofing Fail?

Waterproofing can fail for several reasons. The coating itself is only one part of a successful waterproofing system.

Common causes include:

• Inadequate surface cleaning
• Applying waterproofing over loose or weak material
• Not repairing cracks or damaged areas
• Incorrect coating thickness
• Insufficient number of coats
• Not allowing adequate drying or curing
• Applying the coating on an improperly prepared substrate
• Ignoring underlying structural or drainage issues

For best results, follow the manufacturer's application instructions and ensure that the surface is properly prepared before coating.

Rumido vs Other Terrace Waterproofing Solutions

Different terrace waterproofing systems are designed for different surface conditions and project requirements. Conventional waterproofing approaches may involve membranes, cementitious systems, or other specialized treatments.

Rumido offers a simpler coating-based approach for suitable roofs, terraces, and wall surfaces. Its key advantages include multi-surface adhesion, easy brush application, water repellency, and the ability to reduce surface temperature by up to 7–10°C on porous construction materials.
