High-efficiency, low-maintenance spray rendering machines designed to handle challenging local environments.
As the Democratic Republic of São Tomé and Príncipe accelerates its urban housing expansion and tourism infrastructure projects, the demand for fast, structurally sound, and cost-effective construction technologies is rising. Traditional manual wall plastering is no longer sufficient to meet strict project timelines, especially with the region's intense tropical climate and high relative humidity. Under these environmental pressures, manual cement plastering often suffers from uneven curing, high labor expenditure, and inconsistent finish quality.
Utilizing mechanized automatic cement spray rendering machines helps solve these localized construction pain points. By standardizing the mortar ratio and projecting the plaster pneumatically at high pressure, these machines ensure excellent adhesion to concrete blocks, brick walls, and structural columns. This minimizes raw material wastage—a crucial economic benefit since many high-grade raw cement materials must be imported into the islands.
Protects structures from high-salinity air. Mechanical plastering creates a high-density mortar shell that repels moisture and prevents salt spray corrosion on internal rebars.
Speeds up multi-family residential projects in São Tomé city. Reduces dependence on highly skilled plasterers and shortens wall-finishing schedules by up to 75%.
Ideal for government offices, schools, and hospitals demanding consistent mechanical strength. Ensures wall surfaces meet ISO standards for plaster adhesion.
Engineered for durability and high output, our systems integrate advanced fluid dynamics with robust mechanical structures.
Henan SSG Machinery Co., Ltd. uses high-grade wear-resistant screw pumps (rotors and stators) and pneumatic conveying valves in every plastering machine we build. The components are engineered to withstand the abrasive qualities of local island sands, which often contain diverse granular dynamics. Traditional plastering pumps suffer from premature component failure due to silica abrasive wear; our hardened alloy rotors offer double the service life of standard plastering pumps.
Additionally, our machines feature smart voltage protective units. The electrical grid in São Tomé and Príncipe can experience voltage fluctuations that risk burning out heavy-duty electric motors. SSG plastering sprayers include built-in overcurrent, under-voltage, and thermal overload protection to ensure reliable, continuous operation on site.
Our dual-mix configurations allow operators to switch seamlessly between heavy cement-based mortars for exterior rendering and light gypsum-based dry mixes for interior dry-wall partitions. By managing both density profiles, a single SSG spray machine serves as a complete wall finishing center, reducing capital expenditure for West African developers.
At Henan SSG Machinery Co., Ltd., quality is built into every step. We monitor production from raw steel to the finished plastering machine.

Yes. Because local sand can have irregular grain shapes and varying levels of silica, our plastering machines use hardened high-chromium alloy screw pumps. We recommend using pre-screened sand with a maximum particle size under 3mm and mixing it to the correct proportion to extend rotor and stator life.
We offer both single-phase 220V/50Hz and three-phase 380V/50Hz configurations to match standard construction site power setups in São Tomé. Dual-voltage switchable motors can also be configured upon request.
We regularly ship heavy construction equipment to global markets. We manage the process from our facility in Zhengzhou, through mainland ports, to Port of São Tomé. We supply export documents, including Bill of Lading, Certificate of Origin, and packing lists, to ensure straightforward local clearance.
Depending on the abrasive qualities of your sand and mortar mixture, a standard stator-rotor pair handles between 5,000 to 10,000 square meters of wall area. We provide spare wear parts with each equipment order to minimize project downtime.
Yes, our systems are highly versatile. The feed rate and pressure can be adjusted to handle either dense cement-sand mortars for outdoor walls or lighter gypsum mixtures for internal drywall finishing.
We offer comprehensive technical support, including video startup guides, structural diagrams, and live virtual technician assistance. For large-scale projects, on-site technician deployment can be arranged.
