Liquid Applied Membranes: DRYMAX PU TOPCOAT

DRYMAX PU TOPCOAT

Brushable, elastomeric, water-based aliphatic polyurethane topcoat

Description

DRYMAX PU TOPCOAT is an innovative, brushable, elastomeric, water-based aliphatic polyurethane topcoat. It is used to protect brushable, water-based waterproofing membranes on roofs and common building surfaces. Once dry, it forms a 100% waterproof and seamless membrane that will effectively protect the basic waterproofing layer. It has excellent moisture resistance, high mechanical strength and remains unchanged when exposed to UV radiation.

ADVANTAGES

100% waterproof
Exceptional resistance to UV radiation
Resistance to temperature: -30^oC up to +80^oC
Color stability, without chalking, even after long exposure to UV radiation
Highly elastic - ability to cover small cracks
Excellent compatibility with liquid applied polyurethane, acrylic and hybrid waterproofing membranes (water-based)
Excellent adhesion to porous surfaces even without the use of primer
High friction resistance
High resistance to stagnant water
High resistance to mechanical stress
Good resistance to light pedestrian traffic
Frost resistant
Easy clean surface

APPLICATIONS

DRYMAX PU TOPCOAT is suitable for repairing, refining and revitalizing old and new applications of acrylic, hybrid and polyurethane roofing membranes (water-based), offering a stronger coating with exceptional strength and excellent UV resistance.
It is also suitable for waterproofing terraces, rooftops, pedestrian corridors and other areas.
Recommended for coating polyurethane foam insulation systems.
DRYMAX PU TOPCOAT is recommended for use as a top coat over ISOCRYL PU MAX, ISOCRYL PREMIUM PU HYBRID, ISOCRYL FIBER, FLEX MASTER PU HYBRID and MONOPAL.
It can also be used on many other water-based acrylic, polyurethane or hybrid acrylic–polyurethane waterproofing coatings after conducting a compatibility test.

Instructions for use

Substrate preparation

Careful surface preparation is very important for optimum finish and durability.

Application surfaces must be free from dust, grease, loose residues, and moisture that may affect adhesion.
Do not apply to wet surfaces or when rain is expected.

Application

Stir well before use.
Pour the DRYMAX PU TOPCOAT onto the surface and spread it using a roller or brush until the entire surface is covered.
You can use an airless spray, allowing a considerable saving of manpower.
If needed, apply the second layer at least 3 to 6 hours later and not more than 18 hours.
DRYMAX PU TOPCOAT can be diluted up to 10% with distilled water.
Curing time: 8 – 24 hours depending on temperature and humidity conditions.

ATTENTION

For best results, the temperature during application and curing should be between 5^oC and 35^oC. Low temperatures delay curing while high temperatures speed up curing. High humidity may affect the final finish. Do not apply at low temperatures or when rain or frost is expected in the next 24 hours.

CLEANING

Clean all tools and equipment with water and soap right after application. Cured material can be removed only by mechanical means.
