The product, in perspective.
This water-based masonry preparation coat seals suitable dry plaster before a compatible water-based finish. Specify whether the work is inside or outside and identify the finishing paint.
A water-based emulsion undercoat for suitably dry interior or exterior masonry. The undercoat prepares the finish stage; it does not replace repairing a weak base or addressing moisture problems.
Where it works.
The documented surface or use for Crown Premium Emulsion Undercoat is dry interior or exterior masonry. 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 water-based emulsion undercoat for suitably dry interior or exterior masonry.
- Available quotation packs and component requirements are checked for your selected product, rather than inferred from another grade.
Before you start.
Remove loose particles and confirm the masonry is sufficiently dry. Clean and prepare sound existing emulsion before following the undercoat route.
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 prescribed emulsion undercoat and compatible water-based finishing coats, with the water dilution documented in the sheet.
The undercoat prepares the finish stage; it does not replace repairing a weak base or addressing moisture problems.
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.
What should I choose for the finishing coat?
Use a compatible water-based emulsion topcoat for the prepared substrate and the intended interior or exterior 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.
