Epoxol ® RM-YR is a fully transparent epoxy resin. Designed for industrial and decorative floors, it is based on colored quartz sand. It contains a blend of pure epoxy resins and selected hardeners. It contains no solvents or fillers. Its low viscosity ensures excellent coverage and efficiency. It also penetrates the substrate and fills microcracks.
Epoxol ® RM-YR's key advantages:
- Excellent adhesion: thanks to carefully selected primers and the characteristics of the product itself, it can be applied to various types of concrete substrates.
- High strength: Epoxol ® RM-YR has high resistance to various types of chemicals and excellent impact resistance.
- Temperature resistance: in dry conditions Epoxol ® RM-YR operates in the temperature range from -30°C to +80°C.
- Full transparency: the lack of solvents and fillers allows the product to remain fully transparent, which translates into excellent visibility of the colors of the aggregate used.
- Low consumption: one kilogram of resin, after mixing it with quartz sand in a ratio of 1:6, can produce a floor thickness of up to 4 mm.
Epoxol ® RM-YR application:
- Creating industrial and decorative floors with colored quartz sand.
Substrate preparation:
1. Requirements:
- The substrate should have a minimum tensile strength of 1.5 MPa and a minimum compressive strength of 25 MPa. The concrete grade should be at least C20/25.
- The surface must be clean, free of water, oils, chemicals and other contaminants.
- If there are any gaps in the floor, they should be filled and leveled. This can be done using: Epoxol® Putty Nedour ® CM polyurethane-cement system Neodur ® FT Putty polyaspartic putty . Alternatively, the floor should be primed with a mixture of Epoxol ® Primer SF-P and fine and medium quartz sand, followed by leveling.
- Permissible substrate moisture – up to 4%.
- If there is a suspicion of higher moisture levels deep in the substrate or a lack of insulation from the moisture contained in the soil, it is necessary to use an appropriate primer.
- In the case of a fresh concrete substrate, it should be cured for at least 28 days.
- The substrate should be absorbent, which means a slightly rough structure that will increase the adhesion of the finished product.
2. Priming
To stabilize the substrate, seal pores, and improve the adhesion of the next layer, it is recommended to use a primer. You can use Epoxol® RM -YR as a primer, then apply subsequent layers, or use an alternative primer, NEOTEX® , appropriate for the substrate type and absorbency.
If the substrate has any irregularities, it is recommended to apply a scratch coat, a leveling layer that will eliminate them. This will significantly improve the visual effect. This solution uses Epoxol® Primer SF-P (or Epoxol® RM-YR) epoxy resin mixed with 0.1-0.3 mm
quartz sand If you plan to apply the system at a thickness greater than 1.5 mm, it is recommended to sparsely sprinkle the surface with quartz sand while the primer is still wet. This step is especially important if the colored aggregate is to be applied 24 hours after the primer application. The recommended quartz sand grain size is 0.1-0.3 mm. Theoretical sand consumption should be 0.3-0.5 kg/m². After drying, any loose particles should be removed with a high-suction vacuum cleaner.
Depending on the substrate type, we recommend using an appropriate primer:
- Epoxol ® Primer – intended for dry concrete, seasoned for 28 days, well isolated from the ground (no capillary action), dilute 10% with Neotex ® 1021 (max. substrate humidity 4%).
- Epoxol® Primer SF-P , a primer for dry, cured concrete. Solvent-free, it minimizes unpleasant odors during application.
- Neopox ® Primer WS – primer for fresh concrete (min. 2 weeks old) or wet concrete due to e.g. frequent rainfall (substrate moisture above 4%).
- Neopox ® Primer AY – a primer for concrete cured for 28 days, when it is poorly isolated from the ground and capillary moisture is rising.
Preparation of Epoxol ® RM-YR
Thoroughly mix both components (A and B) in their containers. Then combine them in the appropriate ratio: 100A to 60B and mix again for 3 minutes with a low-speed mixer. Be sure to thoroughly mix the bottom and sides of the container to evenly distribute the hardener. When mixing the components, both separately and after combining, be careful not to introduce air into the mixture.
Application of Epoxol ® RM-YR when sealing colored quartz sand
If Epoxol ® RM-YR is used to seal colored sand, it can also be used as a primer. This is possible with concrete that is dry, clean, and at least class C20/C25.
For a better final result, we recommend using a scratch coat based on the solvent-free Epoxol ® Primer SF-P resin and fine quartz sand in a 1:1 ratio. Then, while the primer is still wet, apply a layer of colored quartz sand until the surface is completely covered (fully saturated). After drying and initial curing, remove any excess sand not bound by the resin, e.g., by vacuuming. The surface can be sealed again with Epoxol ® RM-YR in one or two coats.
Theoretical consumption of Epoxol® RM -YR as a primer:
a) 0.25-0.30 kg/m2 in one layer when applied with a roller.
b) 0.40-0.50 kg/m2 in one layer when applied with a trowel or squeegee.
Theoretical consumption of Epoxol® RM-YR as a sealing layer: 0.40-0.50 kg/m2 in 1-2 layers.
Application of Epoxol® RM Epoxol® QB Clear C-15r system
After the primer has dried, it is recommended to apply an intermediate layer of Epoxol ® Floor in a color similar to the quartz sand, which will be used at a consumption of 250-300 g/m² in a single layer applied by roller, or Epoxol ® RM-YR at a consumption of 500 g/m² in a single layer applied, e.g., with a squeegee for the transparent version. Then, cover the wet intermediate layer with colored quartz sand, with an estimated consumption of Epoxol ® RM-YR at a consumption of 400-500 g/m² in 1-2 layers
. To do this, mix components A and B in the established ratio (10A: 6B by weight) and mix mechanically for approximately 3 minutes using a low-speed mixer. It's important to thoroughly mix the bottom and sides of the container to ensure the hardener (component B) is evenly distributed. Epoxol ® RM-YR is applied as a sealing layer by pouring the prepared mixture onto the floor and spreading it with a squeegee.
