The product, in perspective.
Rain Protek is a coating family for roof and external-wall waterproofing work. Describe the roof or wall material, previous coating and exposure so that the appropriate specification can be confirmed.
A fibre-reinforced acrylic waterproof coating for exposed roofs and walls. Surface defects, drainage and junctions need attention as part of the system. Do not plan it as a thin decorative colour coat.
Where it works.
The documented surface or use for Crown Rain Protek is suitable roofs, concrete and exterior walls. Identify the actual material and its condition before selecting the preparation and finishing system. An existing coating, a newly prepared base and a repaired area can need different treatment.
- A fibre-reinforced acrylic waterproof coating for exposed roofs and walls.
- Available quotation packs and component requirements are checked for your selected product, rather than inferred from another grade.
Before you start.
Check that the roof or wall is sound and prepare the surface, joints and repaired areas according to the waterproofing system. Include the current treatment and water-exposure conditions in your enquiry.
For a useful specification check, share whether the surface is bare or previously treated, the name of the existing coating if known, and any visible damage or moisture exposure. Preparation products should be selected for that condition before the finishing material is applied.
Application and project planning.
Apply the specified waterproofing build and details from the Rain Protek sheet. Coating quantity is connected to the required membrane thickness.
Surface defects, drainage and junctions need attention as part of the system. Do not plan it as a thin decorative colour coat.
Quantity planning starts with the installation: surface area or joint dimensions, the specified system build, and the number of application stages. Include corners, junctions, penetrations or other details relevant to the job. The sales team can check the material list against the project requirements; application must follow the manufacturer’s current instructions.

Good questions, useful answers.
What should I include for a roof enquiry?
Share the roof substrate, approximate area, current coating or waterproofing treatment, visible defects, joints and the type of water exposure.
What should I include in my quotation?
Give the exact product name, requested pack size, quantity and relevant colour reference. Add the surface, application and destination so the product and delivery requirements can be checked together.
How do I choose the right pack and quantity?
Use the available pack choices and the quantity required by your coating or installation plan. Tell us the area, number of coats or relevant joint dimensions if you need help assembling a material list.
Can I confirm a colour from the product picture?
The image represents product packaging, not an exact shade match. Use a manufacturer colour reference for a coloured product, or specify that colour is not applicable for the material you need.
Keep the specification close.
Use the full manufacturer technical information when planning preparation and application. Include the exact product and system details when contacting KariVex about a quotation.
