The product, in perspective.
Crownplast Waterproof Skimcoat is a white cement-based preparation layer for suitable interior and exterior surfaces. It levels uneven areas and pinholes before finishing; request the exact product rather than a similarly named skimcoat.
A cement-based skimcoat to prepare suitable walls for their finishing coats. Do not use a finishing skim to disguise major unevenness or unrepaired defects. Preparation and the subsequent paint system should be planned together.
Where it works.
The documented surface or use for Crownplast Waterproof Skimcoat is suitable interior and exterior surfaces. 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 cement-based skimcoat to prepare suitable walls for their finishing coats.
- Available quotation packs and component requirements are checked for your selected product, rather than inferred from another grade.
Before you start.
Remove loose dust, chalk, contamination and flaking material. Repair major defects first; the sheet distinguishes normal skim preparation from a surface that requires replastering.
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.
Mix with the clean-water proportion and maturation sequence documented for the product, then apply within its working time.
Do not use a finishing skim to disguise major unevenness or unrepaired defects. Preparation and the subsequent paint system should be planned together.
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.
Is skimcoat the same as the final paint?
No. It prepares the wall surface. Choose the subsequent primer and finishing coats for the prepared substrate and the project conditions.
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.
