GOST R 55818-2018 PDF

Full title and description

ГОСТ Р 55818-2018 — «Составы декоративные штукатурные на полимерной основе для фасадных теплоизоляционных композиционных систем с наружными штукатурными слоями. Технические условия». English title: "Polymer base decorative coats for facade's thermo-insulating composite systems with external plaster lays. Specifications". The standard establishes technical requirements, methods of sampling and testing, marking and packaging for factory-produced polymer-based decorative plasters intended for use as external finishes in facade thermal‑insulating composite systems (ETICS/EIFS style systems with external plaster layers).

Abstract

This national Russian standard specifies composition, quality and safety requirements, acceptance and periodic testing regimes, packaging and marking, and test methods for polymer‑based decorative plaster compositions used as outer plaster layers in facade thermal‑insulation composite systems. It includes requirements for physical and hygienic properties (density, pH, non‑volatile content, drying time, adhesion, frost resistance), limits on natural radionuclide activity, combustibility classification and factory documentation.

Scope

The standard applies to factory‑produced decorative plaster compositions based on aqueous polymer dispersions, fillers, pigments and modifying additives, prepared ready for application as outer plaster layers in facade thermal‑insulating composite systems. It sets requirements for raw materials and finished product characteristics, hygienic and radiological safety limits, acceptance and periodic test procedures, marking, packaging and storage conditions. It is intended for use where the outer plaster layer is exposed to atmospheric and climatic effects.

Key topics and requirements

• Definition and classification of factory decorative plaster compositions for facade thermal insulation composite systems.
• Material and composition requirements for polymer dispersions, fillers and additives to ensure specified performance.
• Physical and performance properties: density, pH, mobility/viscosity, non‑volatile matter, drying time to degree 3, resistance to sagging on vertical surfaces, adhesion (bond strength to concrete/substrate), frost resistance, colour and appearance.
• Safety and environmental limits: sanitary‑hygienic requirements, limits on effective specific activity of natural radionuclides (per ГОСТ 30108), and restrictions on emissions of hazardous substances.
• Combustibility classification and requirement to determine combustibility group per ГОСТ 30244 when initiating production or after formulation changes.
• Acceptance and periodic testing procedures for incoming batches (sampling rules, tests to be performed for both factory pastes and hardened samples) and criteria for party acceptance.
• Packaging, marking and documentation: hermetic chemically resistant containers, net mass limits (commonly up to 30 kg), required factory quality documentation and information for export/import operations.
• Specified test methods and references to related test standards (e.g., GOST 19007 for drying time, GOST 31939 for non‑volatile content, GOST 31356 for test concretes).

Typical use and users

Used by manufacturers of facade finishing systems and decorative plasters, product development and quality assurance laboratories, facade contractors and applicators, architects and facade system designers, certification bodies and construction regulators responsible for conformity assessment of ETICS/EIFS external plaster layers. The standard is referenced when specifying or accepting polymer‑based decorative plasters for external thermal‑insulation composite systems.
