Technical Datasheet
| Description/ Useage- |
ProRend Prep is suitable for application on ProBoard cement particle board and insulation systems. It is spatula finished ready for subsequent application of ProRend Colourtex primer and finish coats. |
| Colour- | Grey |
| Application- | |
| Site Work- |
Scaffolding must be tied independently to allow uninterrupted application. Any faults in the structure must be rectified. |
| Site Conditions- |
Do not apply when substrate/ air temperature is below 5oC or above 30oC. Protect areas before and after application. |
| Substrates- |
All surfaces must be dry, sound, clean, reasonably smooth and free from loose material, oil and grease. Protect fresh render work against weather influences. |
| Preparation- |
Remove soft and loose old render layers. Clean well-fixed layers with a high pressure spraying pistol. |
| Render Application- |
Mix dry mortar ProRend Prep basecoat with tap water. Wait for 10 minutes and mix again shortly. Apply with a trowel in a layer of 4 mm thickness. Remove the top layer after some drying. Each layer must not be thicker than 20 mm. It is also easy to apply by machine. |
| Coverage- |
~1.1 kg/m2 for each mm thickness |
| Curing/ Drying- |
Curing with clean water may be necessary during rapid drying conditions. |
| Protection- |
Cover parts which do not have to be treated with paper and tape. Remove directly after applying the primer. |
| Cleaning- |
All equipment must be cleaned immediately after use with water. Waste material should not be emptied into any drainage system. |
| Packaging- |
25 kg paper bag 40 bags per pallet. |
| Storage- |
Can be kept for 6 months in dry, cool conditions. |
