Hi is this paint suitable for a limestone fire surround, if so would I need to prime or sugar soap and how many coats would indeed and would it need a finishing coat .would it be better with a brush or a roller .

While limestone is not listed as a substrate, it can be applied to similar porous substrates such as brick and plaster. We would recommend to test on a small area for compatibility and adhesion prior to full application. Two coats should be applied, the first coat should be left 12 hours prior to the second coat being applied. This product should not be applied by roller.

Can this paint be used on a metal surround of a gas fire?

This product is not suitable for this type of application. It can be applied to concrete, lime, lime cement, cement plaster, sandlime brick and brick surfaces as well as mineral board surfaces.

Can you use this produce on a firewall at the back of a stove and can you deliver to Ireland ?

Assuming the firewall is made of brick, concrete or lime/lime cement, it is bare, clean, dry, sound and prepared in accordance with the technical data sheet, you could consider this product. Dependent on the colour you select, the heat resistance will vary, Ready Mixed White will offer heat resistance up to 300℃, and tinted colour options up to 180℃. Unfortunately, we are currently only able to deliver to Mainland UK, our full delivery terms can be found here; https://www.rawlinspaints.com/content/delivery-terms-pricing .

Can this paint be used on a marble surround of a gas fire?

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.

Hi, can I use this paint in an open fireplace? It will be in direct contact with the flames? Many thanks

Unfortunately no, we do not have a product to recommend for direct flame contact.

is this suitable for a resin fireplace?

Unfortunately no, this is for application to concrete, cement, brick or other mineral board surfaces.

Is this suitable aint to use on the walls that have been roughly rendered in a fireplace that will have a woodburner installed.

Assuming the rendered walls, are clean ,dry, sound and prepared as detailed in the technical data sheet this can be used on areas not exposed to temperatures over 300°C if white or 180°C if a colour is used.

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?

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.

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.

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.

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

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.

Hi, i need a paint that is fire and heat resistant for my small marble hearth in a grey...Which one would you recommend? Thank you
