Isotex prime SB

Solvent based Bituminous Primer.

Iso TEXPRIME SB is cold applied solvent based on bituminous liquid coating. for priming concrete roofs, walls and floor, cement based screeds, bitumen felts, weathered corrugated iron and steel, etc prior to the application of bituminous materials. Iso TEXPRIME SB has been specially formulated for use as primer prior to the use of bituminous waterproofing, adhesive and protective coatings and wide application 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 the 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.

Advantages/Features

Surface Preparation

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

Installation

Iso TEXPRIME SB can be applied with brush, roller or sprayed directly to the surface, second coat if required, should be applied only after the first coat has dried up.

Coverage

1. Concrete : Approx.4sq.m/Ltr (depends upon the surface)
2. Metal Surface : Approx 8sq. m/Ltr

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. Iso TEXPRIME SB 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 exceed 0.2 liters per square meter. Allow to dry thoroughly before over coating, this will normally take 3 to 4 hours depending on prevailing conditions. In very warm climates this drying time can be reduced to approximately 1 hour if the application is external.

Precautions

Iso TEXPRIME SB contains low toxicity but it is a chemical compound and thus prolonged skin, ingestion, eye contact should be avoided. Wear suitable protective clothing gloves. Uses only in ventilated conditions and avoid prolonged inhalation of the solvent vapor. Do not expose to naked flame or other sources of ignition. Skin contamination can be removed using a proprietary hand cleanser. In the case of accidental ingestion or eye contamination seek immediate medical advice.

Health And Safety

Iso TEXPRIME SB is solvent based and will give off inflammable vapors, which may have a narcotic effect if inhaled or absorbed through skin. Use protective coating gloves .No smoking
