Area of Use:
- Internal Filling cavities, holes, unevenness, grooves, patching work in wall and floor areas.
- Levelling and repairing of stairs and landings.
- MJS Ramp-It can also be used to produce ramps and smoothing of floor surfaces and ramps.
Pre-Installation:
- The substrate must be dry, firm, sound, free from dust and release agents.
- MJS Ramp-It adheres to nearly all substrates and is not sensitive to moisture.
Mixing:
- The MJS Ramp-It powder is added to the required amount of water in a clean mixing container and mixed thoroughly to obtain a lump-free and slump-resistant mortar.
- The mix proportions are: 20kg MJS Ramp-It powder to approx. 5.5 to 6.5 litres of water.
Application:
- MJS Ramp-It can be applied from 0 to 20mm in a single application.
- In smaller, well defined areas, such as holes, it can be applied to almost any depth.
- MJS Ramp-It can be feather-edged to match existing elevations.
- For larger areas and thickness over 10mm, MJS Ramp-It should be filled
with coarser sand 0 – 4mm with the mixing ratio of 1.0 vol. mortar and 0.3 vol. of sand. - With dense and primed substrates MJS Ramp-It should be applied at minimum thickness of 1.5mm.
Repairs:
- Apply the mortar with a trowel to holes, cracks and damaged areas, ensuring that the mortar “wets” the surface by trowelling in firmly, leaving the repair proud.
- After about 20 minutes trim off excess and finish off with a wet trowel, sponge or sponge float to obtain a smooth surface.
- As soon as the repair has hardened, the surface of the floor, stair tread etc., can be levelled, if necessary with MJS Level-It floor levelling cement.
Smoothing and Refacing:
- Apply the mixed mortar with a trowel to the required thickness taking into account the short working time.
- The material may be finished with a wet trowel after 15 – 20 minutes
to provide a finish suitable for direct application of floor coverings. - MJS Ramp-It is workable for approx. 20 minutes at 18 – 20°C.
- Lower temperatures lengthen the working time, higher temperatures shorten it.
- MJS Ramp-It is particularly suited for restoring worn out and damaged
steps and stairs. - After approx. 20 minutes trim off excess mortar and finish off with a wet trowel, sponge or float to obtain a smooth surface.
- After hardening of the compound subsequent floor levelling can be done with MJS Level-It levellers.
Precautions:
- MJS Ramp-It can be walked on after approx. 60 minutes at a temperatures of 18° – 20°C.
- Subsequent levelling work should be done immediately after the area is trafficable.
- Should the area be dry already, priming has to be done with ARDEX P 51 diluted 1:3 with water.
- The finished surface has to be protected against direct sunlight and during cure.
- If in doubt install test areas first.
- Please observe the common rules of practice in AS1884 and AS2455.
- In exterior and permanently wet areas MJS Ramp-It cannot be used.
