Painting latex into a mold should be no trouble at all ..I do It all the time ..In fact it is well advised to always paint a "beauty" coat in first to avoid surface bubbles. Be sure to apply a very thin coat of talc or baby powder to your mold first ..this assists in absorption and will also prevent the latex from sticking to is self. Take your gallon jug or 5 gallon bucket of latex and thoroughly shake it up. Pour latex into a plastic party cup. I will usually tint the latex at this time using proline universal tints..not only will it give you a jump start on the base color of your casting, it will assist you in knowing your cure rate as the tinted latex will dry darker. As for the brush..use cheap 1 to 2 inch chip brushes ...dab it it the cup wipe the excess on the rim ..then dab it into the mold ..if you are using a stone mold, the first coat will take the most latex ...just make sure to cover all the area. A secret to saving your brush during the rest of the layers is to keep the brush end down in the cup of latex ..as long as the bristles are submerged in the latex, air isnt hitting it causing it to dry on the brush. The brush will be toast when you are done ..but hey ..it was a cheap chip brush ..you can grab a box of them for like 8 bucks at harbor frieght
