Get Smooth, Even Walls With Rhombus Wall Skimming Filler

If you’re like many homeowners who come to us for help, you don’t like how your wall looks because it has an uneven finish. The good news is that you can fix that using skimming filler, which gives your walls a smooth, even appearance. 

Rhombus Wall Skimming Filler by Rhombus Concrete is a high-quality white cement-based filler formulated to cover imperfections on concrete walls and plastered surfaces. In this post, we look at the advantages of Rhombus Wall Skimming Filler and its easy application process.

Benefits of Rhombus Wall Skimming Filler

  • Smooth & Glossy Finish: Rhombus Wall Skimming Filler produces a beautiful, professional-looking result by covering undulations and imperfections on concrete and plastered surfaces.
  • Resists Flaking: This filler adheres firmly to the surface and resists flaking thanks to its excellent adhesion properties. As a result, the filler remains intact and prevents any ugly peeling or flaking of the painted surface over time.
  • Longer Paint Life: The superior adhesion of the Rhombus Wall Skimming Filler provides a solid base for the paint. It enhances the paint’s ability to withstand daily wear and tear, maintaining its vibrant appearance for a long time.
  • No Curing Required After Application: Unlike some other fillers, Rhombus Wall Skimming Filler does not require a curing period after application. You can start painting immediately after applying the filler. 
  • Water Resistance: Rhombus Wall Skimming Filler has excellent water resistance, a crucial feature in moisture-prone areas. This filler helps prevent moisture penetration and damage to the walls, such as peeling or mold growth.
  • Eco-Friendly: Rhombus Concrete formulates its Wall Skimming Filler with environmentally friendly components to reduce its environmental impact without compromising its performance.

Applying Rhombus Wall Skimming Filler

Clean the walls thoroughly before applying Rhombus Wall Skimming Filler to ensure maximum adhesion. For the best results, ensure you fill any cracks and repair any significant damage to the wall before applying the filler. 

The application process is easy. Measure 25kg of the Wall Skimming Filler and add 35% – 40% clean water by weight. Thoroughly mix the ingredients manually or using a suitable electric mixer to combine them into a paste. Apply the paste evenly on the surface using a skim coat trowel, starting from the bottom and working your way up. 

We recommend applying a maximum of two coats (layers) of Crystal Filler. The maximum thickness of the first and second coats (layers) should be 1-1.5 mm and 0.7-1.0 mm, respectively.

Why Rhombus Concrete is Now Using Manufactured Sand in the Production of Ready-Mix Concrete

Since its establishment, Rhombus Concrete has led the construction industry in innovation, production efficiency, quality control, cost-effectiveness and sustainability.

We have also been about moving the sector from traditional to modern methods.

It is along these lines that we have introduced the use of manufactured sand; replacing natural sand and river sand that people have been using since the beginning of time.


What Is Manufactured Sand?

Manufactured sand (M-Sand) is artificial sand produced from crushing hard stones into small sand-sized angular-shaped particles, washed and finely graded to be used as construction aggregate and for the production of ready-mix concrete.


How It Is Manufactured?

Rocks or quarry stones are blasted and subjected to a series of crushing cycles to reduce the particles to the size of naturally occurring sand.

The produced sand is then sieved and washed to remove fine particles and impurities and tested for various quality aspects before it is deemed fit for use.


Importance of Manufactured Sand

In this day and age; the construction industry needs to adopt the use of manufactured sand for the following reasons:


  1. Global Scarcity of Natural Sand

Increased sand mining and continuous depletion of natural aggregate sources have led to the scarcity of natural sand, making it unsustainable to continue relying on it.

  1. Cost Effective

The scarcity of natural sand and river sand has led to a dramatic rise in prices of the same. In addition, most sand pits producing the required quality of sand are often located in remote locations, leading to high costs in transportation. When these costs are passed on to consumers, construction becomes expensive.

  1. Growing Demand for Fine-Aggregates in Construction

Nearly 65-80% of the volume of concrete and screed mixes is made up of sand/aggregates. This demand must be met by sustainable solutions.

  1. Presence of Silt and Clay in Natural Sand

Natural sand is inherently high in silt and clay, which can be damaging for screed and concrete.

  1. Reduction of Wastage of Low-Value By-Products in the Quarry

The low-value aggregates formed as a by-product of rock crushing can be utilized efficiently to create a high-value product. This is important for the circular economy.


Advantages of Manufactured Sand

  1. Manufactured Sand Is More Cost Effective

Manufactured sand is derived from more readily-available materials and can be produced in areas closer to construction sites – bringing down the cost of production and transportation.

  1. Compliance with International Standards

Manufactured sand can be used as aggregates in screed and concrete mixes, as per EN13139 standards. It can be used as a replacement or as a blended mixture with natural sand.

  1. Less Disruptive to the Environment

The land used for quarrying rock can be reclaimed for commercial/residential purposes or used for wetland restoration. This can help in reducing the sand mining from river beds.

  1. Lesser Impurities

Manufactured sand is free of silt and clay particles, and has denser particle packing than natural sand. It also offers higher flexural strength, better abrasion resistance, higher unit weight and lower permeability.

  1. Desired Properties

In manufactured sand, you get desired properties like shape, smooth texture and consistency and required gradation of fines. The cubical shape and proper gradation give good flexibility, durability, higher strength and long life to the concrete.

  1. Higher Compressive and Flexural Strength

Manufactured sand is graded with precision and consistency thus it has a higher fineness modulus compared to natural sand and crusher dust. Additionally, the physical and chemical properties in M-Sand are balanced and can withstand any harsh climatic conditions.

  1. Overcoming Defects.

With manufactured sand; you can overcome the defects in concrete like segregation, honeycombing, corrosion of reinforcement steel, voids, capillary, bleeding etc.


All these factors considered – we usher all of you to the brave new world of manufactured sand. Join us in making construction safer, sustainable and affordable.




Rhombus Concrete Launches a Concrete Recycling Plant

We are proud to announce that, once again, our company has taken an innovation lead in the new and emerging industry that is Ready-Mix Concrete by launching the first Concrete Recycling Plant in Kenya.

In construction, there is a lot of waste and possibilities of environmental pollution. Cement emits dust and a lot of water gets wasted. Additionally, during concreting, and especially traditional mixing, some water with cement and other aggregates will escape to the ground causing environmental hazards.
