M416 Lightweight Screed
M416 uses the high strength gypsum, superfine inorganic filler and other additives, is green product, have good liquidity, specialized for the thick layer of ground leveling, heating backfill leveling (except kitchen and bathroom area),can fast automatic leveling the ground and single construction thickness of 50 mm. After 24 hours, a flat and solid base can be reached. It is a high-tech product to replace the traditional cement mortar leveling.
Features:
Primary construction thickness of 50mm;
Low shrinkage, excellent crack resistance;
Good leveling and high construction efficiency;
Lightweight insulation,can be used for heating backfill;
Low alkali formula, environmentally friendly.
Application Places:
Suitable for leveling at the base level of light ground such as home, office and hotel.
Surface Treatment:
The base must be dry, solid, dust-free, pollution-free sundries. To ensure good adhesion, absorbent surface such as concrete, MSYH interface agent was used for fief treatment.
Technical Parameters:
Mobility: ≥130mm
Applied temperature: 10~30℃
Mixing ratio: product (25kg) : water (10-11L)
Available time: ≥ 20min
Compressive strength (absolutely dry) : ≥16 (MPa)
Flexural strength (absolutely dry) : ≥4 (MPa)
Application:
1. After the original base is cleaned, appropriate primer should be selected and applied to the surface. After the primer has been absorbed by the original base and dried and solidified, start applying the backfill.
2. Pour 10-11L of water into the mixing container, then slowly add a pack of backfill. Blend with blender for 3-5 minutes and no clumps. Pour out the mixture, spread evenly and spread evenly with spatula or special toothed scraper until desired thickness, or the transmission capacity of 20-40 KL/min pump slurry to the required thickness.
3. The mixture shall be applied within 20 minutes. The freshly constructed slurry shall avoid direct sunlight and strong wind.
4. Before the initial setting of the product, the air brought in during mixing should be eliminated. It is recommended to conduct defoaming to ensure the smooth surface.
Reference Consumption:
Product consumption is about 13.5-14kg/m²·10mm. The actual amount depends on the construction thickness and actual conditions of the surface.
Notes:
This product is not recommended for long-term wet environment. Avoid outdoor use. Avoid long soaking after the product is fully hardened.
Packaging and storage:
25kg/bag. This product must be stored indoors, pay attention to moisture-proof, waterproof, rainproof and prevent insolating. Pallets should be stacked in no more than 8 layers. Under the condition of good moisture-proof measures Shelf life is 6 months.
