Sikalastic® HLM 5000 R

(former MSeal HLM 5000 R, Davco K10 Polyurethane)

LIQUID, COLD-APPLIED WATERPROOFING MEMBRANE SYSTEM

Sikalastic® HLM 5000 R is a single component, moisture curing, polyurethane based waterproofing membrane that cures by reaction with atmospheric moisture to form a tough membrane.
Sikalastic® HLM 5000 R protects structures from water penetration while remaining flexible to handle the nominal expansion and contraction of substrates.

  • Waterproof - Protects structure from water penetration
  • Elastomeric - Permits nominal expansion and contraction of the structure
  • Low Temperature Flexibility – Wide service temperature, suitable for all climates
  • Single Component – No complex mixing & easy to use
  • Cold Applied & Seamless – Eliminates lapping, seaming and precutting
  • Available in Two grades – Easy application on vertical and horizontal surfaces

Application steps

SUBSTRATE PREPARATION

All concrete deck surfaces should be lightly steel troweled to a flat, uniform surface. A light broom finish is acceptable. New concrete must be properly water cured at least 14 days. Membrane curing compounds must be mechanically removed.


Remove dust, dirt and other contaminants just before or during application. Surfaces must be dry at the time of application. Air-void pockmarks or honeycombs must be opened up to allow Sikalastic® HLM 5000 R to fill the cavities completely.

 

APPLICATION

A test application is always recommended before proceeding with entire application.
Select the grade of Sikalastic® HLM 5000 R that best meets individual job requirements
For horizontal applications, empty contents of pail and spread immediately to ensure workability. Best results are obtained by marking off 11 m² areas and evenly spreading the contents of 25 Kg unit with a rubber-edged notched squeegee.
For vertical applications, apply by trowel / roller at the rate of 0.4m²/Kg.
Verify the applied thickness with a wet film gauge as the work progresses.
The integrity of the cured membrane on a horizontal surface is verified by damming the entire area and flooding with water to a depth of 50mm and allowing the water to stand for 24 – 48 hours. Visually inspect the bottom surface to check for any water penetration. If repairs are necessary, the area should be drained and allowed to dry before reapplying Sikalastic® HLM 5000 R. After application, the area should be tested for membrane integrity

CURING TREATMENT

Appreciable properties develop within 24–48 hours at 24°C and 50% relative humidity. Protect Sikalastic® HLM 5000 R from traffic during curing.
 

DRAINAGE AND PROTECTION
For protection during backfill and where hydrostatic pressure is anticipated, use a suitable geotextile to divert the water.
For protection during backfill only, install protection board as soon as possible following cure of Sikalastic® HLM 5000 R.
