Features & Benefits

Why specify Licalastic Scud elastomeric waterproofing coating?

☀️

Can Be Left Exposed — UV Resistant

Unlike cement-based waterproofing membranes, this elastomeric waterproofing coating is UV resistant and can be left fully exposed without additional protection — ideal for terraces, balconies and roofs where a finished coloured surface is required.

👣

Foot Traffic Resistant

Licalastic Scud elastomeric waterproofing coating withstands foot traffic — tested to static indentation load category P4 — making it suitable for walkable terraces, balconies and accessible roof areas without requiring a separate wear course.

🏅

Dual Certification

Certified to both UNI EN 14891 (waterproof coating for subsequent tile laying) and UNI EN 1504-2 (concrete protection coating, PI/MC/IR principles) — this elastomeric waterproofing coating covers both waterproofing and concrete protection requirements.

🎨

Available in 4 Colours

Available in white, red, grey and green — this elastomeric waterproofing coating provides a finished decorative surface as well as waterproofing protection, eliminating the need for a separate decorative finish coat on exposed applications.

⚡

Ready to Use — No Mixing

Supplied ready to use in 5kg and 20kg buckets — no water, no powder, no mixing equipment needed on site. Manual stirring only before use. Significantly faster to deploy than powder-based waterproofing products.

🌍

Solvent Free, Odourless, Non-Toxic

Water-based formulation — odourless, non-flammable and non-toxic with no solvents. Suitable for use in enclosed spaces including bathrooms, showers, sauna rooms and basements with adequate ventilation.

Product Description

Licalastic Scud — Ready-to-Use Elastomeric Waterproofing Coating

Licalastic Scud is Licata's mono-component liquid elastomeric waterproofing coating — supplied ready to use in aqueous dispersion, based on modified acrylic copolymers with synthetic fibres and inert fillers. Once cured, it creates a durable, impermeable elastic barrier resistant to atmospheric agents, UV rays, stagnant water and foot traffic — including in marine and industrial environments.

This elastomeric waterproofing coating is certified to UNI EN 14891, making it suitable as a waterproof substrate for subsequent tile laying using Licata adhesives. It also meets UNI EN 1504-2 requirements for concrete protection — preventing CO2 penetration and protecting concrete from carbonation (CO2 permeability Sd >50m).

Licalastic Scud elastomeric waterproofing coating can also be used to restore old bituminous waterproofing — apply after a preparatory coat of Licalastic Svart diluted at 10% on new bituminous membranes, or repair and reprime old existing sheeting before overcoating. On large surfaces or where movement is expected, embed Lica Armor 1000 or Texture 2000 reinforcement fabric between the first and second coats.

Preparation

Preparing for elastomeric waterproofing coating

1
Clean and prepare: Remove all flaking parts. Surface must be free of dust, detergents, oils, greases, waxes, gypsum, salts and dry. Check internal residual moisture and ensure no free or stagnant water is present.
2
Damp substrates: On surfaces with damp or negative pressure moisture, apply EpoxyCem TX epoxy cement primer before this elastomeric waterproofing coating.
3
Repair defects: Fill holes, gravel nests and cracks with Licata Repair mortars. Seal slots with LicaFlex 100 polyurethane sealant before applying the elastomeric waterproofing coating.
4
Dusty surfaces: On very dusty or powdery surfaces, apply a priming coat of this elastomeric waterproofing coating diluted 50% with water before full application.
Application

Applying the elastomeric waterproofing coating

1
Ready to use: Licalastic Scud requires no mixing — stir manually before use. Do not use mechanical mixers.
2
Apply by roller, spatula or brush: Use a sponge or short-hair roller, rubber knife or smooth spatula. Use a brush for corners and detail areas.
3
Multiple coats: Apply at least 2–3 coats at intervals of 3–4 hours. Each coat must not exceed 1mm thickness. Apply each coat perpendicular to the previous one.
4
Reinforcement fabric: On large surfaces, movement-prone areas or over old bituminous sheeting, embed Lica Armor 1000 or Texture 2000 reinforcement fabric between the first and second coats — overlap side flaps by at least 5cm.
5
Detail areas: At corners, edges, floor-wall junctions and interfaces between different materials, use LicaBand BTS 100 self-adhesive waterproofing tape in conjunction with this elastomeric waterproofing coating.
Do not apply on iced, thawing or wet substrates. Do not exceed 1mm per coat. Protect the fresh elastomeric waterproofing coating from direct sunlight, strong wind and rain for at least 24 hours. Temperature must be between +5°C and +35°C.
