Sikagard® 552 W Aquaprimer is best used in areas where moisture and humidity is a concern and works as part of a system that protects the substrate and ensures a long term protective solution. Ideal as a priming coat for concrete and dense mineral substrates like fibre cement, aerated concrete, gypsum and thin rendering such as Sika® MonoTop®-620 etc.
Sikagard®-552 W Aquaprimer can also be used as a primer on firmly adhering existing water based coatings or under cement resurfacing mortar to improve
the adhesion in case of concrete surface treated with hydrophobic impregnation. Sikagard®-552 W Aquaprimer is part of a system: Suitable for protection against ingress (Principle 1, method 1.3 of EN 1504-9), Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9), Suitable for increasing the resistivity (Principle 8,
method 8.3 of EN 1504-9).
The substrate must be dense and free from loose and friable particles. Tensile strength of the substrate must be more than 1 N/mm2. Exposed concrete without existing coating. Suitable preparation methods are steam cleaning, high pressure water jetting or blastcleaning. New concrete must be at least 28 days old.
Thin layer rendering: If required, a levelling pore sealer/smoothing coat (e.g. Sika® MonoTop®-620, Sikagard®-545 W Elastofill, etc.) shall be applied – refer to the respective product data sheet. For cement based products, allow a curing time of at least 4 days before priming. Exposed concrete with existing coating
Existing coatings must be tested to confirm their adhesion to the substrate - adhesion test average: > 1.0 N/mm2 with no single value below 0.7 N/mm2 for subsequent top rigid coating; > 0.8 N/mm2 with no single value below 0.5 N/mm2 for subsequent top elastic coating respectively.
Sikagard® 552 W Aquaprimer has been designed for application to concrete, and dense mineral substrates such as, fibre cement, aerated concrete, gypsum and smooth coatings like Sika Monotop 610.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
