Sometimes, the plasterer’s trowel leaves fine lines or ridges that only become obvious after painting.

if the plaster was not completely dry before painting, or if a mist coat (a diluted first coat of paint) was skipped or poorly applied, paint can absorb unevenly. perhaps paint shrinking due to uneven drying, absorbtion or even due to the contamination from the substrate...

sometimes, pva adhesive (used to seal old walls before plastering) can splash onto the surface or be used excessively. if not properly absorbed or if it dries on the surface, it can prevent paint from sticking, causing streaks, spots, or marks

The problem likely lies with the setup of the concealed cisterns or the connection to the toilet pans.

• low water level your toilet's cistern needs a specific volume of water delivered quickly to create a powerful, effective flush.if the water level is set too low, the flush will be weak. manufacturers typically mark a fill line on the inside of the tank, usually about an inch below the overflow tube.the installer may have set the level too low, or the components may be misaligned;

the float mechanism inside the cistern needs to be adjusted to allow more water to fill the tank after each flush. this is a common fix for weak flushing;

• improper flush valve settings dual-flush cisterns have adjustable flush valves to control the volume for both the full and reduced flush. it's possible the "full flush" setting on the valve itself is not correctly configured to release the full 6 liters.

the flush valve, which is the large component in the center of the cistern, can be adjusted. often, a lever on the valve can be moved to change the water level for the flush.

• flush rod adjustment for concealed cisterns operated by push buttons, the rods that connect the buttons to the internal flush mechanism must be the correct length. if they are not set correctly, pressing the button may not fully activate the flush mechanism, resulting in a weak or partial flush;

the flush rods can typically be screwed in or out to adjust their length. tightening them may be all that is needed to fully engage the flush mechanism and provide a more powerful flush.


• obstructed flush pipe: the pipe connecting the cistern to the toilet pan might be pushed too far into the back of the toilet, which may result in the obstruction of the water flow and a weak flush;

the pipe may need to be pulled back slightly to ensure there is no obstruction to the water flow.

• cistern height: the height of the concealed cistern may require adjustment, perhaps replacing the siphon. a cistern that is mounted too low may not provide enough gravitational force for the water to flush the bowl effectively.

• component compatibility while less likely, an installer might claim that the toilet pan and cistern are incompatible "eco items" that inherently have a poor flush.

You may require a rubber reducer like the one below, or similar.

A mist coat is typically used on highly porous surfaces like fresh plaster. the water thins the paint, allowing it to soak into the plaster and seal it, it also helps to prevent the subsequent, thicker snd undiluted emulsion coats of paint from drying too quickly or being absorbed unevenly, potential flaking or cracking.

a dedicated concrete primer is generally considered more reliable for concrete surfaces, as it is specifically engineered to handle the alkalinity and moisture characteristics of concrete. a primer's main function is to create a strong bond between the substrate and the topcoat.some advanced primers chemically bond to both the concrete and the paint, creating an exceptionally strong and permanent bond.concrete can contain significant moisture, especially when it is fresh. applying paint directly to damp concrete can lead to peeling and flaking. some specialized primers are designed to be applied to new or damp concrete, tolerating relative humidity up to 98%. this allows for painting to begin much sooner than waiting for the concrete to dry completely. these primers often create a water-resistant film that prevents moisture from causing paint failure.

i personally tend to use mapei primer g, sika or cheaper version below.

the everbuild sbr bond is a latex based, water-resistant bonding agent and admixture for use in areas subject to humidity, dampness and continuous water contact. improves water resistance of cement mixtures by forming a reinforcing polymer that increases long-term durability and flexibility of the mix on renderings and floor screeds.

polymer emulsions of this type have been used extensively over the last 20 years by the building industry as an admixture for cement and concrete applications, including repair and renovation, surfacing of floors and bonding generally. it contains anti-foam to control the density of cementitious mixes and is also freeze thaw stable, with improved frost resistance.

it offers greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc.
