HTS30
HTS30 clear end-grain sealer (waterborne)
Waterborne sealer for the end grain of boards, beams and logs — keeps out moisture, mould and checking. Soaks deep along the fibres, seals the end and leaves a clear, elastic, vapour-permeable film with good adhesion, so moisture leaves the end grain evenly and the ends crack less while the timber dries. Shows the grain, silky-matt look. Interior and exterior.
- end grain of beams, logs, boards, cladding
- glulam and LVL
- edges of plywood, chipboard, hardboard, OSB
- log/timber houses, fences, garden furniture, balconies, small garden structures
- end-grain joints

Process and compatibility
- Substrate preparation
- End clean, free of dust, dirt, resin, snow/ice; fresh or re-cut end. Wood may be green — the vapour-permeable film is meant to let it dry slowly without checking.recommended
- Don'ts
- don't apply in frost or rain or onto a wet/iced end
- don't thin with solvents
- don't sand the cured film on the end
