Sikalastic® HLM 5000 R

(former MSeal HLM 5000 R)

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.

For extremely porous block: Prime with a coat of Sikalastic® HLM 5000 R diluted up to 5% with xylene.
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 MSikalastic® 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 10 m² areas and evenly spreading the contents of 22.5 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.
