Cement Mortar Spray Machine For Cement Plastering And Waterproof Coating

It is designed for spraying cement plaster, waterproof coatings, putty powders, grouting and general mortar projection work — e.g., plugging leaks in tunnels/dams, crack and structure reinforcement, indoor/outdoor waterproof spraying, garden and craft spraying.

Cement mortar/plaster, waterproof mortars and grouts, putty powder coatings, latex paint (when properly thinned), grout mixes and other pumpable cement-based or low-viscosity coatings — provided particle size and consistency meet the machine limits.

Rated voltage: 220V; rated power: 800–1100 (check product label/manual for unit, typically W); flow: 0–6 L/min; hopper capacity: 15 L; vertical pumping distance: up to 15 m; horizontal distance: up to 15 m; maximum aggregate size: 0–1 mm; net weight: 20 kg; dimensions: 700 × 400 × 850 mm.

Maximum aggregate (sand) size is 0–1 mm. Do not use coarser aggregates to avoid clogging and pump damage.

The specified maximum vertical distance is about 15 m and the horizontal distance is about 15 m. Actual performance depends on material viscosity and mix consistency.

Prepare a smooth, lump-free, pumpable consistency within the machine's limits: use fine sand (≤1 mm), proper cement-to-sand ratio and add water or plasticizer/admixture as needed. Strain the mix through a mesh to remove lumps and test on a small trial to adjust viscosity before full application.

1) Place machine on stable surface and connect to 220V supply. 2) Prepare and strain the mix. 3) Fill hopper (15 L) and secure hoses/nozzle. 4) Set spray/pressure adjustments per manual. 5) Start machine, test spray, adjust mixture or nozzle, then proceed with consistent spraying motion. Always follow the user manual for detailed startup procedures.

Flush the hopper, pump and hose immediately after use with plenty of water (or appropriate cleaner for non-waterborne materials). Disassemble and clean nozzle and seals regularly, inspect hoses and wear parts, and lubricate moving parts as recommended in the manual. Prompt cleaning prevents blockages and prolongs life.

Yes — low-viscosity or properly thinned latex paints can be sprayed, but you must confirm paint compatibility, dilute to pumpable viscosity, and thoroughly clean the machine after use. Do not spray highly solvent-based coatings unless the machine and seals are rated for them.

Yes, it can be used indoors for plastering and coatings, but ensure adequate ventilation, use appropriate PPE (respirator, goggles), and protect nearby surfaces. Take electrical safety precautions when operating in enclosed or wet areas.

Wear PPE (respirator, eye protection, gloves, protective clothing). Ensure equipment is properly grounded and power supply is safe. Do not spray flammable solvents. Release built-up pressure before servicing. Keep hands and body parts away from nozzle under pressure and follow lockout procedures before maintenance.

Clogging: check mix consistency and strain mix; clean nozzle/hose. Low or no pressure: verify power supply, inspect pump seals and hoses for leaks. Uneven spray: adjust mix viscosity and nozzle settings, check for blocked or worn nozzle parts. Persistent faults: consult service manual or supplier.

Nozzles, seals/gaskets, hoses, pump pistons or diaphragms and O-rings are common wear parts. Keep these spares on hand to minimize downtime.

The machine is relatively portable for job-site use — net weight is about 20 kg and dimensions are 700 × 400 × 850 mm. It requires a 220V power source, so portability depends on availability of power or a generator.

Warranty terms and service options vary by supplier. Check the product documentation or contact the seller/manufacturer for warranty length, authorized service centers and spare parts availability. Keep purchase and maintenance records to assist with claims.
