Pratley's original epoxy putty was ground breaking as the first epoxy putty when invented in the early 1960's, and was chosen to travel to the Moon on Apollo 11.

Pratley Quickset White Glue: Pratley is also an industry leader in small size DIY epoxies. Pratley labels them as glue, but they are in fact super high quality 2 part epoxies  For small repairs like joining one small to average sized fractured gravestone the Pratley Quickset White Glue 40 ml is an excellent choice. Two tooth paste style resealable tubes come in each package.

Pratley Quickset Clear Glue: There is also a clear to part epoxy that is less thick then the white glue, however is thinker then a liquid. It is excellent for small repairs to stone, pottery or glass and is very stable and will not discolor. It can be pigmented.

Please note: Disposable gloves are highly advised when working with and mixing any epoxies for personal safety.

Pratley Putty is sold in individual packets, boxes of 20 packets, or industrial sized boxes of ten units with less packaging and larger unit size.

All putties are sold in units with 2 parts. Basic mixing  directions for all putties. Cut off equal amounts with plastic knife or razor and mix in your hand, gloves advised. Once color blends together it is ready to apply.

Akemi - Akepox Epoxies: 

A great epoxy product line for outdoor applications, Akepox provides various  options in viscosity, commonly called thickness, delivery methods and size options. Most epoxies are designed to be structural and not be seen as they will tend to yellow from sunlight. The 5000's Akepox epoxy are UV stable and will remain 99% clear and can also be pigmented, which works best with the Akemi pigments sold as a set.

By far the most cost effective packaging to the consumer is found in the 2 piece sets of medium sized metal containers. They are sold by weight with the larger of the 2 canisters being twice the weight of the smaller container, in each 2 piece set.

The majority of the Akemi- Akepox Epoxies that Atlas Preservation sells are considered to be knife grade epoxy. This means they have the consistency that allows them to generally be applied with a knife or spatula hand tool. (ASTM C 717-07a)

 Atlas Preservation also stocks liquid and penetrating epoxies that will be discussed later in this product selection guide.

All epoxies are effected by temperature in two major ways, thickness and curing time. The higher the temperature the thinner the epoxy becomes. The higher the temperature the faster it will harden, referred to as curing time. The higher the air circulation rate the faster the curing time in many situations.

The temperature must be above freezing for curing to take place. As long as the epoxy does not freeze it will eventually cure, but in 40 degree f weather is will take a long time,  up to 12- 24 hours. In warm weather above 85f it will be very fast, sometimes within 20 minutes.

In lower temperatures above freezing the epoxies will become very stiff and hard to mix. I advice storing them indoors and when traveling I bring my epoxy box into the motel overnight. High temperature can also be a problem. If in direct sun and above about 90f all epoxies will become much thinner.

Flowing Epoxy

Akemi Akepox 5000: This is a clear liquid two-part epoxy which is flowing and good for adding pigment for coloring. This is also a UV stable epoxy which will not discolor in direct sunlight.
