Stellmann Aqualine PU Pro – Concrete Floor Coatings

Description

Stellmann Aqualine PU PRO is a coloured concrete floor coating system for interior and exterior areas. It is a premium quality dual-component PU coating and offers outstanding mechanical and chemical resistance and is UV-resistant. Both components are low odour and VOC-free. The system is water soluble and can be used on floors off mineral substrates such as industrial halls, factories, stairs, cellars, commercial kitchens, passageways, corridors, garages parking lots, etc. It can also be used on concrete walls (interior and exterior). Stellmann Aqualine PU PRO can be applied with a P3, P4 and P5 slip-rating.

Note: Stellmann Non-Slip Particles need to be added to Aqualine PU PRO in order to achieve the required slip rating.

Application Guide

Surface Preparation

New concrete must cure for a minimum of 28 days before applying Stellmann Aqualine PU PRO. Ensure surface is thoroughly dry before application (< 3% building material moisture). The surface must be structurally sound, and the substrate compressive strength should be at least 25MPa. The substrate tensile strength should be at least 1.5N/mm². All non-structural cracks and holes need to be repaired. In general, the surface to be treated needs be clean and free of all traces of loose material, dirt, debris, oil, grease, old coatings, curing compounds, release agents, laitance, dust and other contaminants. All new or old concrete surfaces should be prepared by mechanical grinding, abrasive blasting, etching, or any other suitable preparation/cleaning methods. Always check if all traces of oil and other contaminations have been completely removed before applying Stellmann Aqualine PU PRO. Substrate must be sealed off from rising moisture. Apply sample area in case of doubt.

Application Procedure and equipment

Use PEKA Multitex Rollers. Stellmann Aqualine PU PRO is applied in two stages. The first layer acts as the “prime” layer and the second coat as the finish layer. A third layer is optional for high traffic areas. Add the Stellmann Non-Slip Particles only to the finish coat.

Dilution Rates

Dilute first “prime” coat with 20% of water (mixture of part A and Part B) for new applications. Dilute second finish coat with 0-10% of water. For renovations (previously applied Stellmann Aqualine PU PRO projects) dilute first “primer” layer with 0-10% of water. Dilute the second layer with 0-10% of water.

Mix ratio: 5;1. Part A = 5 and Part B is 1.

Calculation: Multiply the amount of Part A poured in mixing cup/bucket by 0.2. The result is the amount of Part B that needs to be added.

• Stir up Part A for 5 minutes with a mechanical mixer at low speed before use.
• When mixing in smaller portions, use a clean mixing cup and an electrical precision scale to measure the mixing ratios.
• When mixing smaller portions use a 5 to 1 mixing ratio by weight. Mix Part A and B with a clean mechanical mixer for at least 5 minutes.
• Do not use milliliter mixing cups as product density is higher than water. Mixing without electrical precision scale will cause off ratio mixing. Any warranty is void when mixing is not conform instructions.
• See extensive installation manual for a step-by-step guide.

Application

Do not apply a thick layer. A wet film thickness above approx. 150μm can cause “CO2-bubbles” in the coating.

Prime Coat: Mix the coating according to the 5-1 mixing ratio. Dilute the mixture in accordance with the above instructions with water. Apply the first layer to the surface. Only apply the second layer after first layer has dried (within 24 hours after applying the primecoat).

Finish Coat: Mix coating according to the 5-1 mixing ratio. Add Stellmann Non-Slip particles in the mixture (between 2 and 3% by weight) and dilute in accordance with the above instructions.

The finish coat should be applied evenly. Apply in sections in a straight line and always finish in the same direction (away from the applicator). Do not use W or N shaped movements. Do not roll back into areas that are curing to avoid buildup of the non-slip particles. IMPORTANT: Do not add more than 3% of the Stellmann Non-Slip particles to the mixture. Adding more particles will not increase the slip-rating.

• Use mixing bucket/cup and an electronic precision scale.
• Stir Part A thoroughly before use with an electrical mixer. Use a separate and clean mixer to stir the mixture of Part A and B thoroughly before use.
• Only mix as much coating as will be immediately required. Securely fasten the lids of unused product to ensure it will not solidify.
• Practical spreading rates will vary depending on such factors as method and conditions of applications and surface roughness.

Slip Ratings

The Stellmann Non-Slip Particles are added to the mixture of Part A and B as a percentage by weight. Use an electrical precision scale to measure. Mix in particles with an electrical mixer.

• P3 Stellmann Non-Slip Particles: add 3 % by weight
• P4 Stellmann Non-Slip Particles: add 2.5% by weight
• P5 Stellmann Non-Slip Particles: add 2.5% by weight

Example

You mixed 2.4kg of Stellmann Aqualin PU Pro (2kg of Part A and 0.4kg of Part B). You want to achieve a P3 slip-rating. Therefore, you multiply 0.02 x 2400 = 48. Add 48 grams of the Stellmann Non-Slip P3 Particles to the mixture.

Curing

At 20°C and 65% relative humidity and well-ventilated areas:

• • Dust dry: ca. 2 hours
  • Re-coatable: ca. 12 to 24 hours
  • Trafficable: ca. 24 hours
  • Full curing time: ca. 3-7 days, depending on load, humidity, and temperature

Precautions And Limitations

Read Data Sheet, Material Safety Data Sheet, and any precautionary labels on containers. Do not apply in exterior situations when rain threatens. Do not apply when relative humidity is above 80% or is likely to go above 80% shortly after the application has been completed. Practical spreading rates will vary depending on such factors as method and conditions of applications and surface roughness and porosity. Suitable for application over concrete substrates.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
