I've Purchased Your Emulsion And It Is Not Covering Properly
Tikkurila products are made in Finland for a Nordic market, we do not modify them for the UK. This means some of the application properties of our products are different and this can catch new users out. Poor coverage is a fairly common question when customers use our emulsion products for the first time particularly Optiva 3, 5 and 20 from our durable range.
In most instances (with the exception of very bright primary colours) it is a very simple case of either not applying enough product or overworking the material across the surface. Tikkurila emulsions are highly flexible and have a tremendous ability to pull back naturally, removing the stipple effect from the wall leaving a solid non textured surface. Tikkurila products are not designed to be overworked and flattened using the roller, they are designed to pull back naturally as the product dries.
If the surface being painted is looking a little patchy after a first coat, trust the product and apply a little more paint to the surfaces with your second coat, and work the film less, you will see a stipple but trust the paint will pull the texture out. Once you get used to the product and its drying characteristics painting walls and ceilings should become much easier as less working of the film is required.
Issue: Poor hiding / Grinning
Cause: Low Film Build / Overworking
Solution: Do not overwork the product, trust it will pull back flat
