Isotexprime WB Solvent-free Bituminous Primer

Isotexprime WB is a cold applied bituminous primer. It is a solvent-free primer for priming concrete roofs, walls and floors, cement based screeds, bitumen felts, weathered corrugated iron and steel, etc, prior to the application of bituminous materials. It has been specially formulated for use as a primer prior to the use of bituminous waterproofing, adhesive and protective coatings and wide applications in the construction industry. Main use is as a primer for concrete and cement based substrates, especially porous and dusty surfaces, prior to the application of bitumen based liquid coatings such as ISOTEX range, bitumen based sheet membranes such as the roofing felt ISOFLEX and the bitumen based joint sealants ISOSEAL. It can also be used to prime metal prior to the application of a protection coating against corrosion of pipes, structural steelwork and other metallic equipment.

USES:

  • Primer for rubber or Bituminous membrane
  • Standard primer coat for metals, concrete and masonry surface for application before roof felts, membranes and similar bituminous waterproofing membrane and protective coating
  • Damp proofing coating
  • Excellent adhesion properties.

SURFACE PREPARATION:

Surfaces should be clean and free from dirt, dust, grease or rust.

INSTALLATION:

IsoTEXPRIME WB can be applied with brush, roller or sprayed directly to the surface Second coat, if required, should be applied only after first-coat has dried.

COVERAGE

1. CONCRETE: Approx.4sq.m/Lt (depends upon the surface)
2. METAL SURFACE: Approx 8sq. m/Lt

STORAGE:

One year in air tight closed containers a temperatures 10-60ºC

PACKING:

Available in 20Litre pails and 200 Liter drums

APPLICATION.PROCEDURE

All surfaces should be free from dust, dirt, oil, grease, and loose material as far as possible and must be dry. If the surface is ferrous metal then all rust must be removed, corrugated metal sheet should be allowed to weather sufficiently. IsoTEXPRIME WB should be well scrubbed in by brush, ensuring only a very thin coating is applied or applied thinly by spray. Application rate, depending on the porosity of the substrate, should be in the range0.10 to 0.15 liters per square meter. Certainly the rate should not exceed0.2 liters per square meter. Allow to dry thoroughly before over coating, this will normally take 3 to 6 hours depending on prevailing conditions. In very warm climates this drying time can be reduced to approximately one hour if the application is external.

HEALTH AND SAFETY PRECAUTIONS

IsoTEXPRIME WB is a totally non hazardous friendly material. Still, eye contact should be avoided. Wear suitable protective clothing and gloves .Use ventilated conditions and avoid prolonged inhalation. Skin contamination can be removed using a proprietary hand cleanser. In the case of accidental ingestion or eye contamination seek immediate medical advice. IsoTEXPRIME WB is water based and will not give any inflammable vapors.
