Question: 

I'd like to paint the old discoloured terracotta tiles in fireplace hearth before a wood burner is installed. Is this paint suitable? Do you do colour swatches? is the M497 grey its hard to tell

Answer from Rawlins’ Technical Team: 

Unfortunately no, this is not suitable for application to terracotta tiles.

Assuming the tiles are not exposed to direct flame contact, they are ceramic tiles, they are clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Stonelux Primer & Undercoat followed by Stonelux Fireplace Paint.

Stonelux Colour Sample Pots and Stonelux Colour Chart are available.

Answer from Rawlins’ Technical Team:

questions Sarah Herchak on 2022-10-23 12:31:55
Question: 

I have already started using this paint on a resin fireplace surround. Why isn’t it suitable? What paint would you recommend for this please?

Answer from Rawlins’ Technical Team: 

Unfortunately resin is not a compatible substrate for this product.

This product can withstand temperatures of upto 300°C but it does not isolate the substrate it is applied to from those temperatures.

Assuming the resin fireplace is clean, dry, sound and prepared as detailed in the technical data sheet you could consider Stonelux Primer & Undercoat followed by Stonelux Fireplace Paint.

Surfaces painted with Stonelux Fireplace Paint must be a minimum of 100mm (10cm) away from any heat source.

This paint can withstand upto 300°C.

questions Steve on 2022-07-26 20:05:28
Question: 

I am refurbishing a 90 year old fireplace opening and chimney breast. The opening will house a typical stove with >100mm clearance. My current plan is to clean the brick and paint with a suitable fireplace paint, There are a few areas when the bricks (hard clay) are heavily contaminated with soot. With considerable effort, the baked-on soot can be removed from the brick surface. However, even when very thoroughly cleaned, it is clear smoke contaminants have soaked into the brick. I am unsure whether this contamination could cause staining of a painted finish over time or adhesion issues during application. I assume my situation is not unique. Is there relevant guidance for either TIKKURILA MUURI or STONELUX paints?

Answer from Rawlins’ Technical Team: 

Soot can be very difficult to clean in Tikkkurila's experience and whilst an alkaline cleaning agent such as Tikkurila Maalipesu Cleaning Agent may help it will all depend on how contaminated the surfaces are and what type of fuels/combination of fuels have been burnt over the last 90 years or so.

You have correctly pointed out that any remaining soot could cause issues for the paint system and possibly discolouration/bleed through, but until the work is done it will be difficult to know what effect, if any the remaining contamination will have.

I guess the only advice is to clean the surfaces as best as possible and then paint a small trial area, leave for a sensible period to establish if there is any noticeable problem with adhesion, discolouration, or bleeding.

The alternative is to just clean and leave the surface un-treated/natural.

questions Antony Davies on 2022-06-14 13:05:06
Question: 

HI, is this product suitable for painting direct onto fireboard that is what makes up the bay that my log burner is set into? Thank you.

Answer from Rawlins’ Technical Team: 

This is suitable for use on concrete, lime, lime cement, cement plaster, sandlime brick and brick surfaces as well as mineral board surfaces.

The product can be thinned upto 10% with clean water if necessary.

After the primer coat has set for at least 12 hours, finishing coat should be applied.

questions Louise  on 2022-04-27 20:22:02
Question: 

Hi, is this suitable for the wooden part of the fire surround rather than the walls? Thanks

Answer from Rawlins’ Technical Team: 

Unfortunately no this is not suitable for application to wood.

Assuming the wood is bare, clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Stonelux Primer & Undercoat followed by Stonelux Fireplace paint.

This is available in a range of colours in various stone finishes.

Surfaces painted with Stonelux Fireplace Paint must be a minimum of 100mm (10cm) away from any heat source.
