My garage has acrylic paint on the walls and ceiling. Can I use this effectively as a topcoat? Or if not, is there an alternate product?

This will not work as a top coat, Master Flame has to be applied prior. Unfortunately we do not have an effective product for you. Thank you!

How do you use it on palm tree leafs. Do you have to let them dry out first, and how often do you reapply?

Let the palm leaves dry out, then spray them on both sides. Let dry for 24 hours. Thank you!

Does this meet flame retardant technical bulletin 133? That's what our town requires for fabric in our school.

It meets the requirements for schools in Virginia Beach, VA according to the Fire Marshall who re-inspected our school after we treated all curtains and bulletin Boards that were fabric covered.

Can I apply this product directly to eps foam ( expanded polystyrene ) ? and then applied water base paint?

Depends upon what you're trying to do with the EPS. It might adhere, but it probably won't keep the EPS foam from bursting into flames when it gets hot enough to outgas. I have seen requirements to cover structural plastics with Type X gypsum to provide an acceptable level of smoke and flame containment. One EPS product I reviewed had flame spread of 20 and smoke of 100-300, which might actually meet "Class A interior wall and ceiling finish" requirements (UL 723), but only to limited height (e.g., 48 inches), unless also tested under NFPA 253 for flashover. You would need to find a product that is intended for your purpose (e.g., as interior finish), rather than trying to coat a dangerous product with fire retardant.

Does it work

Did a test on an old piece of wood. It seems to really work. Remember it is a fire retardant not fire proof

Excellent product

Thank you for this excellent product. It is very light and easy to apply, and the wood absorbed it completely without leaving any residue. The material was tested using the ignitability test according to BS EN ISO 11925-2:2020, and it performed very well.

Couldn’t be easier to apply

Couldn’t be easier to apply, covers a lot of area thoroughly. Haven’t tested its fire resistance however. Appreciate that the chemicals don’t seem particularly dangerous to work with.

This product was tested and found effective by my local fire department.

Used this as a seal coat on wall framing , sheetrock and wood trim. I made treated and untreated samples of the framing wood, sheetrock and painted wallpaper on sheetrock. They were tested by the local fire department. The untreated samples burned easily, but the treated pieces were difficult to burn.

Tested!

Flame tested and this product is great. Sprayed with HVLP gun on seat material and wool product. Will not burn even with constant fire by blowtorch.
