Primer Plus CimentArt
An adhesive primer based on acrylic copolymers designed to improve the adhesion of CimentArt microcement and mineral layers. It is primarily recommended for smooth, low-absorbency, and non-absorbent substrates such as ceramic tiles, porcelain, marble, granite or wood.
- Increases adhesion
- For low-absorbency substrates
- Transparent when dry
- Interior and exterior use
Reliable substrate bonding
Why use Primer Plus
A quality primer reduces the risk of insufficient adhesion of subsequent layers. Primer Plus increases surface cohesion and creates an optimal base for CimentArt microcement systems.
Increased cohesion
Helps unify the surface and supports the stability of subsequent cement and microcement layers.
More durable system
Contributes to increased surface durability, reducing defects and improving protection against substrate alkalinity.
Designed for smooth and low-absorbency surfaces
Suitable substrates for Primer Plus
The Plus version is intended primarily for surfaces with low absorption where a reliable adhesive intermediate layer is required before microcement application.
- ceramic tiles and slabs
- porcelain and vitrified tiles
- marble and granite
- stable wooden substrates
- smooth mineral surfaces
- low-absorbency concrete and cement substrates
- renovation of existing stable surfaces
- interior and exterior projects

First system layer
Position of Primer Plus in the system
Primer Plus is applied to the prepared substrate before the base microcement layer. Its role is to create an adhesive intermediate layer between the original surface and the CimentArt system.

Primer is not a substitute for substrate preparation
View technical data sheetThe surface must be solid, clean, dry, degreased and free from loose parts before application. Smooth substrates generally require appropriate mechanical abrasion.
Simple working process
How to apply Primer Plus
Apply the product evenly and in a suitable amount. Excessively thick layers, puddles or runs can negatively affect drying and the adhesion of subsequent layers.
- 01
Substrate check
Verify surface strength, stability and cohesion. Remove loose parts, dirt, wax and grease.
- 02
Mechanical preparation
Roughen smooth ceramics, stone or other sealed surfaces as necessary and then vacuum thoroughly.
- 03
Even application
Apply Primer Plus by brush, roller or airless spraying avoiding excess, puddles and runs.
- 04
Drying
Allow to dry for about 30 minutes or until the surface is dry to the touch.
- 05
Subsequent layer
After drying, proceed with the base Aqua Base layer or other prescribed layer according to the system composition.
Coverage depending on absorbency
Primer Plus consumption
Actual coverage depends on texture, porosity, absorbency and application method. Coverage on smooth, low-absorbency substrates is lower than on rough or more absorbent surfaces.
Approximate coverage
Approximately 10–14 m² per 1 kg product depending on substrate condition and absorbency.
Highly absorbent surfaces
Approximately 5–7 m² per 1 kg. For very absorbent surfaces, the correct primer type should be assessed.
Low-absorbency surfaces
Approximately 10–15 m² per 1 kg depending on smoothness and application method.
Critical application points
Requirements to observe
The substrate must be solid, stable, clean, dry and free from grease. Primer Plus does not replace crack repair, level levelling or removal of loose layers.
Damaged surfaces should be repaired first. If necessary, a second layer can be applied and problematic substrates strengthened with suitable CimentArt fibreglass mesh.
Apply only the necessary amount. Do not create puddles or excessively thick continuous layers. Wash tools with water after application.
Packaging and storage
How to store Primer Plus correctly
Store in the original hermetically sealed container in a dry place protected from the weather. Declared shelf life is 12 months.
Available pack sizes
Primer Plus is available in 1 kg, 5 kg and 25 kg packs.
Shelf life
Up to 12 months in original sealed packaging when stored correctly.
Tool cleaning
Clean brushes, rollers and other equipment with water immediately after use.

Frequently asked questions
FAQ for Primer Plus
What is Primer Plus used for?
It is used to increase the adhesion of CimentArt microcement and mineral layers to prepared substrates. It is mainly intended for smooth and low-absorbency surfaces.
Is Primer Plus suitable for ceramic tiles?
Yes. Ceramic tiles must be solid, stable, thoroughly degreased and mechanically abraded if necessary. Joints and unevenness must be resolved according to the system composition.
How long does Primer Plus take to dry?
The approximate drying time is about 30 minutes. Apply the next layer only when the surface is dry to the touch. Actual time depends on temperature, humidity and applied thickness.
How is Primer Plus applied?
The product can be applied by brush, paint roller or airless spraying.
What is the consumption of Primer Plus?
Typical coverage is approximately 10–14 m² per 1 kg. On low-absorbency surfaces, coverage can be around 10–15 m²/kg, on highly absorbent substrates about 5–7 m²/kg.
Is it visible after drying?
The product is milky white during application and becomes transparent after complete drying.
Can two layers be applied?
On damaged or problematic surfaces where the substrate has been repaired, a second layer can be applied if necessary. Suitability should be assessed based on surface condition.
Is Primer Plus waterproofing?
No. Primer Plus improves adhesion and contributes to system impermeability but does not replace structural waterproofing or the full protective microcement system.
Is it suitable for exterior use?
Yes, the technical data sheet states it is for both interior and exterior use. The substrate must be properly prepared and subsequent layers must conform to the full outdoor system specification.
How to clean application tools?
Clean tools with water immediately after application before the material dries.
