Follow the recommended procedure for filling suitable cracks and minor defects in rendered surfaces. The guide explains how to prepare the application nozzle, apply the material without flattening the surrounding texture and complete a small test repair.
View instructions for applying Mendrend Flexible Penetrating Acrylic to affected render. This colour-matched coating can be used to address staining and colour variation or to blend areas repaired with Mendrend Fissure Infill.
Consult the current health and safety document before handling, applying or storing Mendrend products. Appropriate personal protective equipment and safe working practices should be used throughout the repair.
Always request and test a colour sample before placing the full order. Render colour can vary according to manufacturer, batch, age, weathering and application conditions, even where the original shade is known.
Apply a small sample in an inconspicuous position and allow it to dry fully before assessing the match. A test repair or sample panel is also recommended to confirm that the application method produces an acceptable texture and appearance.
Newly formed cracks should generally be monitored to establish whether movement is continuing. Mendrend is intended for decorative render repairs and must not be used to conceal or correct structural defects. Cracking associated with structural movement should be assessed by a suitably qualified professional before repair work begins.
The appropriate repair method will depend on the width and stability of the crack, the existing render texture and the extent of any staining or colour variation. Contact Rendit for technical advice if the cause of the defect is uncertain or if previous repair attempts have altered the surrounding surface.
