The product, in perspective.
Roofmaster is a waterborne acrylic roof finish with a matt appearance. Identify the roof substrate and existing coating so preparation and compatibility can be checked before sourcing.
A roof finish with substrate-specific preparation and application guidance. Roofmaster and Roof Paint are separate products. Keep the selected name and coating system consistent in the quotation.
Where it works.
The documented surface or use for Crown Roofmaster is suitable roof substrates. 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 roof finish with substrate-specific preparation and application guidance.
- Available quotation packs and component requirements are checked for your selected product, rather than inferred from another grade.
Before you start.
Remove loose coatings and biological contamination where present. New masonry, previously painted masonry and galvanised metal have different primer or preparation routes.
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.
Companion products to specify
The technical sheet references these materials for its preparation, thinning or coating scenarios. Confirm the scenario for your substrate.
Application and project planning.
Follow the Roofmaster coat sequence and water dilution for the identified substrate. Address preparation before planning the colour coat.
Roofmaster and Roof Paint are separate products. Keep the selected name and coating system consistent in the quotation.
Measure the area to be treated and allow for the number of coats required by the coating system. Surface texture, absorption, application method and material losses can change the amount needed. Tell us the area and proposed system when requesting packs; the published coverage is a planning reference, not a guarantee of your project’s consumption.

Good questions, useful answers.
Can I request a roof finish without knowing the old paint?
Yes, but describe its condition and the roof material, and include a photograph if available so the preparation can be checked.
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.
