Exterior Paint Prices: Comparing 20-25 kg Products

Exterior paint prices should be compared per m², not per bucket. Compare 20-25 kg textured coatings, elastic coatings and waterproofing products in one table.

Exterior Paint Prices: Comparing 20-25 kg Products

Everyone researching exterior paint prices falls into the same trap: putting the label prices of two different 20 or 25 kg buckets side by side and choosing the cheaper one. Yet some large-pack exterior products are smooth paints, some are textured coatings and some are waterproofing materials; at the same weight they cover very different areas. In this article we compare Silkcoat's 20-25 kg exterior products by function, binder and area of use, and explain how to convert bucket price into real cost.

Key Takeaways

  • What needs to be compared on a facade is not the bucket price but the cost per square metre, including primer and number of coats.
  • 20-25 kg packs are mostly textured coatings, elastic textured coatings or waterproofing materials; smooth topcoat paints come in 15 L buckets.
  • Textured coatings give texture in a single coat and reduce filling/repair labour; smooth paints require a smooth surface and are applied in two coats.
  • Consumption figures vary with the absorbency of the surface; for exact figures check the product's technical data sheet and measure on a small test area.

Why Bucket Price Is Misleading

The cost of an exterior product has three components: material, labour and surface preparation. Even the material item alone is not equal to the bucket price; the product's consumption per square metre, the number of coats required and the dilution ratio are the real determinants. A textured coating covers less area per kilogram, but it is applied in a single coat and, because it hides minor surface defects, reduces filling labour. A smooth topcoat paint covers more area per litre but requires two coats and a properly prepared surface.

The mistake we see most often in practice is comparing a textured coating and a smooth paint by weight alone. If a comparison is to be made, it should be between products in the same class, and the total system cost (primer + topcoat + labour) should be calculated.

Silkcoat's Exterior Products in 20-25 kg Packs

The table below groups the exterior products on the site that are offered in 20 kg or 25 kg packs by their function. Because prices vary by region, dealer and season, no figures are given here; for current prices and consumption values, refer to the relevant product page and technical data sheet.

The most important thing the table shows is this: of the eight 25 kg products, only a few are direct alternatives to one another. Silkoterasit and Ruloser can be compared within the same class; Stone and Subend are bought for different jobs, and putting their bucket prices side by side is meaningless.

Why Are Smooth Topcoat Paints Not on This List?

Silkcoat's smooth exterior paints, Silicone, Acrylic, Elasticoat and Hydroclean, are offered in 15 L packs and sold by the litre. A “20 kg” search will not lead you to these products when comparing prices, but if you want a smooth, texture-free facade, this is the right product group. For these products the cost is calculated over two coats, and the cost of primer must always be added.

In short, someone searching for “20 kg exterior paint” actually has one of two different needs: either they want a textured coating, or they hope to save money by buying a large pack. In the first case the textured coatings above are the right choice; in the second, the 15 L smooth paints.

Five Steps to Calculating Cost per Square Metre

  1. Measure the surface area: Multiply the height of the facade by its width and subtract window and door openings. Do not forget balcony undersides and parapets; these are the areas most often left out of measurements.
  2. Take the product's consumption from the technical data sheet: Each product's consumption range per square metre is given in the technical data sheets. Use the upper limit on absorbent, rough surfaces and the lower limit on smooth surfaces.
  3. Add the number of coats: Allow two coats for smooth paints and usually a single coat for textured coatings. If the colour change is large (dark to light), a third coat may be needed with smooth paint.
  4. Account for the primer: Add the consumption of Silikon Astar in a silicone system or Akrilik Astar in an acrylic system. Skipping the primer looks like a saving in the short term but leads to premature wear of the topcoat in the long term.
  5. Add labour and scaffolding: Material is only one part of the total cost. Putting a more durable product on the same scaffolding and labour is often more economical than the cheapest bucket.

Features That Raise the Price and Pay for Themselves

The main factors that create price differences between products in the same class are:

  • Silicone additive: Increases water repellency and delays dirt pick-up and algae growth on the facade. In rainy regions the difference shows in the first winter.
  • Elasticity: Bridges hairline cracks. On south-facing facades with large temperature swings, it reduces paint flaking caused by cracks.
  • Fibre reinforcement: Strengthens the film in textured coatings and prevents the texture from crumbling over time.
  • Binder quality: A pure acrylic binder provides higher adhesion and colour retention than an acrylic copolymer; this is the main reason for the price difference in smooth topcoat paints.

Which of these features you need depends on the orientation, climate and current condition of your facade. Choosing the same product for a north-facing facade exposed to constant wind and rain and for a sheltered inner courtyard means either unnecessary expense or inadequate protection. The exterior facades application area page covers these criteria in detail in terms of climate and dirt resistance.

Sample Comparison: Two Scenarios for the Same Facade

Since figures vary by region, rather than giving amounts here, let us show the logic of the calculation through two scenarios. Assume the facade has old plaster, hairline cracks in places and faces a rain-exposed direction.

  • Scenario A: Textured coating. Crack repair, Akrilik Astar and a single coat of Ruloser Silikonlu. Because the texture hides minor defects in the plaster, filling labour is reduced. Although material consumption looks high per kilogram, total labour and preparation costs fall.
  • Scenario B: Smooth paint. Crack repair, levelling with exterior filler, Silikon Astar and two coats of Silicone. Less material is consumed per litre, but preparation labour increases in order to achieve a smooth surface.

The totals of the two scenarios often come out close to each other; what determines the difference is the current condition of the facade and the desired appearance. On a facade with plaster defects, A is more economical; on a facade with sound plaster where a modern look is wanted, B is. Looking only at the bucket price without doing this calculation can lead you to think the more expensive of the two scenarios is the cheaper one.

We covered the durability and protection side of choosing exterior paint separately in the article on long-lasting facades through the right exterior paint choice; reading the price comparison together with those criteria leads to a sounder decision.

Common Mistakes

  • Comparing a textured coating and a smooth paint by weight alone.
  • Looking only at the topcoat price without accounting for the primer.
  • Estimating consumption instead of taking it from the technical data sheet, and running out of product mid-job.
  • Using buckets from different batches on the same facade without mixing them and ending up with shade differences; on large surfaces, combine the buckets and mix until homogeneous.
  • Using waterproofing material (Subend) instead of a topcoat paint; Subend is a protective layer and must be covered with a suitable topcoat.

Conclusion: The Right Comparison Leads to the Right Decision

A 20 kg or 25 kg pack is not a product category in itself; it covers different jobs such as textured coating, elastic textured coating and waterproofing. A sound price comparison is only possible by first identifying the need (texture, smooth surface or waterproofing) and then comparing products in the same class on cost per square metre.

The concrete next step: work out the square metres of your facade, choose two products that suit your needs from the exterior paints and primers and calculate the total cost using the consumption values in the technical data sheets.

Frequently Asked Questions

It differs greatly by product class: textured coatings cover less area per kilogram because they are textured, while smooth paints cover more. The exact value should be taken from the consumption range in the product's technical data sheet; on absorbent, rough surfaces use the upper limit.

Binder quality (pure acrylic or acrylic copolymer) and silicone, fibre and elasticity additives determine the price. In addition, because different classes such as textured coating, elastic textured coating and waterproofing material are sold at the same weight, bucket prices cannot be compared directly.

Measure the facade area, multiply the consumption value from the technical data sheet by the number of coats, add primer consumption and then add labour and scaffolding costs. Looking only at the topcoat bucket price understates the real cost.

On surfaces with plaster defects, a textured coating can be more economical overall because it gives texture in a single coat and reduces filling labour. On smooth surfaces, smooth paint is applied in two coats and covers more area per litre. The decision should be based on the condition of the surface.

On facades exposed to rain and wind, yes: the silicone additive increases water repellency and delays dirt pick-up and algae growth. In a sheltered inner courtyard or a region with little rainfall, a standard acrylic copolymer coating may be sufficient.

Yes. Skipping the primer on absorbent surfaces leads to uneven absorption of the topcoat, a patchy appearance and premature wear. Silikon Astar should be used in a silicone system and Akrilik Astar in a standard acrylic system, and both should be included in the cost calculation.

No. Subend is a protective layer for balconies, parapets and points where water can pool; it is not a topcoat paint. A system-compatible exterior topcoat must be applied over it.

To avoid shade differences on large surfaces, buckets of the same colour should be combined in a large container and mixed until homogeneous before application. Applying bucket by bucket can lead to noticeable shade transitions on the facade.
