Monoprufe WP Elastic Elastomeric surface damp proof membrane FEATURES • below ground structures • internal and external application • suitable for use on concrete, brickwork, blocks • highly elastic, elongation at break 180% • excellent adhesion; pull off > 1.0N/mm² • easy to use • water based Monoprufe WP Elastic is a high performance cold applied cementitious waterproofing membrane. Monoprufe WP Elastic is used in swimming pools, tanks and basements to contain or exclude water and can accommodate some structural movement within the substrate. Supplied as a two component material, Monoprufe WP Elastic is a blend of polymers, cements, graded fillers and chemical binders. The two components are simply mixed at site to form a highly workable coating which is roller applied to the prepared substrate. It is to be covered with a screed or render; it is not capable of resisting wear or abrasion.

Site results will differ. When Monoprufe WP Elastic is being covered with a bonded Ronafix [or other Ronacrete modified] screed or Ronafix render it is essential that the substrate is sound and stable and strong enough to restrain the screed or render. The instructions given in the appropriate Ronacrete screed or render specification Continued on following page...

Monoprufe WP Elastic Elastomeric surface damp proof membrane Instructions for Use (continued) must therefore be followed. Typically the tensile strength of the substrate must exceed 1.5N/mm² - refer to BS8204 Part 3:10993 for test method. Achieve a clean, laitance free substrate. When mechanically abrading surfaces, vacuum blasting is preferable. A heavy surface profile should be avoided in order to minimise the risk of the Monoprufe WP Elastic ponding or not covering high points. When overlaying with an unbonded screed, surface preparation requires the substrate to be clean, sound and free of...

Monoprufe WP Elastic Elastomeric surface damp proof membrane Instructions for Use (continued) a glass fibre fleece should be introduced, approximately 150mm either side of the point of possible movement. The fleece should be embedded in a coat of Monoprufe WP Elastic and encapsulated with a further coat. Neither of these coats may be regarded as part of the waterproofing and at least two further coats must be applied. Avoid application in strong direct sunlight or drying winds. Observe material pot life. Do not re-work or add water. The wet film must be protected to ensure it is not walked on...

Monoprufe WP Elastic Elastomeric surface damp proof membrane Site Attendance When on site Ronacrete representatives are able, if asked, to give a general indication of the correct method of installing a Ronacrete product. It is important to bear in mind that Ronacrete Ltd is a manufacturer and not an application contractor and it is therefore the responsibility of the contractor and his employer to ensure he is aware of and implements the correct practices and procedures to ensure the correct installation of the product and that liability for its correct installation lies with the contractor...
